Playing tournament golf in Japan is always a memorable experience and at the recently staged International Series Japan presented by Moutai, competitors chose to honour this in the best way possible – by giving back to the community.
A wealth of competitors, including the champion Lucas Herbert from Australia, donated equipment to the Japan High School and Junior High School Golf Association, one of the nation’s leading supporters of grassroots golf.
Golf balls, hats and gloves were all gifted to the association during the week, helping to ensure the country’s up-and-coming golfers have a surplus of quality golf products.
The contributions helped played an important part in an unforgettable week at Caledonian Golf Club, which marked the first time The International Series had visited Japan.
Said Herbert after his win: “I had the pleasure of first coming to play in Japan as an amateur at the start of my career and it’s just a special place. I had some of the best food I have ever had this week, and it’s just been an incredible experience.”

Yuta Sugiura, one of Japan’s rising stars and a two-time winner on the Japan Golf Tour, finished as the leading local player in a tie for second place.
The 23-year-old is an inspiration to the country’s next generation of golfers, including the aspiring golfers at the Japan High School.
“We are so grateful to the Asian Tour and The International Series for these wonderful donations to our students,” said Hisahiko Inoue [main picture with Cho Minn Thant, Commissioner & CEO, Asian Tour], Chairman, Japan High School and Junior High School Golf Association.
“These gifts will be a great incentive to our golfers to try and reach the next level and follow in the footsteps of players like Yuta Sugiura. Golf in Japan continues to be very popular and we are trying to play our part in helping it to grow.”
Five players from Japan finished in the top-10 at the International Series Japan presented by Moutai – including Jinichiro Kozuma, who plays on the LIV Golf League – showcasing the strength in depth of the powerful golfing nation.
The completion of the International Series Japan presented by Moutai at the weekend – won so magnificently by Australian Lucas Herbert – meant for the third successive event The International Series boasted a strong presenting partner.
And with the International Series Cambodia presented by Royal Group recently unveiled, The International Series is most definitely in the spotlight in 2025.
All 10 events have now been finalised with five boasting presenting partners. Four of them are groundbreaking inaugural tournaments while another features a brand new title sponsor, highlighting the growing attraction of the brand.
Launched in March 2022 as a LIV Golf-backed series of elevated events on the Asian Tour, the series got underway at the International Series Thailand at Black Mountain Golf Club, Thailand.
Since that inaugural tournament, the series has visited 15 countries including destinations in the Middle East, North Africa and the United Kingdom, firmly establishing The International Series as a global brand, while providing the best playing opportunities to elite golfers as well as the best regional and local talent.
Fast forward to May 2025. The series continues to expand, with four new markets this season, in India, Japan, Cambodia and the Philippines.

The addition of a legacy event, the Singapore Open, further strengthens a robust calendar which also features welcome returns to Macau, Morocco, Indonesia, Hong Kong and Saudi Arabia.
The growing appeal of the brand is evident by the addition of strong commercial partnerships supporting each of the new events.
Giant real estate company DLF was presenting partner of the International Series India; Chinese beverage maker Moutai presented the International Series Japan; Cambodian conglomerate Royal Group will present the International Series Cambodia, and Bingo Plus will present the International Series Philippines.
Earlier this year saw the second edition of the International Series Macau presented by Wynn, further evidence of the brand’s appeal.
Moutai has also been named as title sponsor of the storied Singapore Open, a legacy event in the region which returns to the Asian Tour calendar after a hiatus of three years.
Rahul Singh, Head of The International Series, said: “The International Series is making a real impact on the industry and contributing to an unheralded new era for the sport, transforming the golf landscape for everyone, from global superstars to regional talent and prodigious amateurs.
“Driven by our unique offering, we have made significant commercial strides particularly in 2025, welcoming numerous new partners, cementing the allure of The International Series as one of the most attractive opportunities in men’s professional golf.”
The impact of The International Series is not just commercial. A number of players from the Asian Tour have taken the pathway to the LIV Golf League in the past four years, while the appearance of superstars such as Bryson DeChambeau, Joaquin Niemann and Patrick Reed on the series has further elevated the offering.

LIV Golf CEO Scott O’Neil said: “LIV Golf is committed to creating more player pathways throughout professional golf, and The International Series continues to play a huge role in the sport’s global growth.
“The Series is bringing many of golf’s biggest names to new markets while opening opportunities for the stars of tomorrow to compete with the very best, and we couldn’t be more excited for its future.”
Next stop on the series is the International Series Morocco – being played at Royal Golf Dar Es Salam (Red Course), 3-6 July.
LIV Golf star Lucas Herbert put on a putting masterclass to win the International Series Japan presented by Moutai last week, at Caledonian Golf Club.
The 29-year-old from Australia topped the Putts per Greens in Regulation (GIR) category with 1.531, with Thailand’s Atiruj Winaicharoenchai second on 1.583. Herbert also ranked third in Putts per Round with 26.75, behind only Korean Younghan Song, with 26.25, and Atiruj, on 26.5.
Thanks to his brilliant performance on the greens, Herbert impressively posted under-par scores on 37.5% of the holes, and led both the Most Birdies and Most Eagles categories for the week with 23 birdies and four eagles respectively.
His other stats for the week were also strong: Driving Distance 307.2 yards (10th), Fairways Hit 64.29% (T18), and GIR 68.06 (T35).

Japan’s Yuta Sugiura was very good at keeping bogeys off his scorecard, making only two for the 72 holes and four less than anyone else who made the cut. He also produced solid stats in the Putts per Round and GIR categories with 27.5 (T9) and 72.22% respectively.
Song not only topped Putts per Round but also led both the Putts per Round and Putts per GIR categories after three rounds, and was sixth in Putts per GIR with 1.617.

Lucas Herbert has moved to the top of The International Series Rankings following his stunning five-shot victory at the International Series Japan presented by Moutai at the weekend.
The Australian, who plays for Ripper GC on LIV Golf, led from the start after a course record-equalling nine-under-par 62 on Thursday at Caledonian Golf Club, and although he was five adrift with three to play on Saturday, he roared to victory thanks to two eagles in his closing three holes which got him a three-way share of the lead going into the final day.
A closing 64 was enough to see off nearest challengers Yuta Sigiura of Japan and Younghan Song of Korea, and the dominant display underlined Herbert’s rich vein of good form this season that has already generated three top-five finishes and three top-20 results in seven LIV Golf League events.
“The strength of the field was very good. I have played in Japan a few times over the years, and the field strength is always good,” said Herbert, who is becoming something of a specialist in the Land of the Rising Sun as his last tournament win was also there, at the ISPS Handa Championship in 2023.
“It’s tricky. It feels like I am playing an away game against these guys on their home turf. Their games are all structured and built to play really well in Japanese courses. So it is tough to beat them at their own game at times.

“That’s why the two wins I have had in Japan have felt quite special, because it feels like winning an away game like in other sports when you are beating these guys on their home venues, against home crowds too.”
Herbert shot up 20 positions to pole on the rankings thanks to the 180 points earned, and he leads the International Series Macau presented by Wynn winner Carlos Ortiz of Mexico and International Series India presented by DLF champion Ollie Schniederjans by 22.95 points, with Bryson DeChambeau and Patrick Reed tied fourth, a further 70 points behind.
American Schniederjans missed both the Macau and Japan dates because of injury, and will be hoping for a return in time for International Series Morocco from 3-6 July.
The winner of The International Series Rankings earns a place on the ensuing season’s LIV Golf League – a lifechanging opportunity on the groundbreaking franchise.

Namseoul Country Club, venue for the GS Caltex Maekyung Open, is always a stern test – especially because of the notoriously difficult greens.
This year was no exception. The conditions were especially tough on Sunday, when strong, gusty winds and firm and fast greens pushed the scoring average up to 73.391, on the par-71 layout.
The par-four 18th hole at Namseoul is always a difficult hole, and even more so with the traditional Sunday pin on the top shelf of the slick two tiered green. After averaging a score of 4.325 in the first three rounds, the hole averaged 4.972 on the final day. One player recorded a sextuple bogey 10, while there were five triples, nine doubles and 35 bogies against only four birdies. Not surprisingly, the 18th ranked as the most difficult hole on the course on Sunday, and was second behind the 16th hole for the week.
However, the champion Doyeob Mun from Korea had no trouble with the 18th on Sunday making a birdie, a feat only three other players matched, and produced a spectacular bogey free eight-under-par 63 in the final round for his first Asian Tour victory. Incredibly, he beat the scoring average on the last day by more than 10 shots, winning by three over the trio of Jazz Janewattananond from Thailand and Koreans Baekjun Kim and Junghwan Lee, after starting the day six shots behind the leaders.
Mun finished joint top in the Fewest Bogies or Worse column with six. He ranked second in Greens in Regulation (GIR) with 76.39%, and he was third in scrambling with 76.47%.

He was also accurate off the tee hitting 73.21% of the fairways and placing T5 in this category. Mun’s other stats for the week were very consistent: Putts per GIR 1.782 (21st), Putts per Round 29.5 (T21), Driving Distance 293 yards (18th).
Seven-time Asian Tour winner Jazz had a good week on and around the greens and he ranked second in Putts per Round with 26.75, T8 in Putts per Green with 1.714 and fifth in Scrambling with 73.33%. He also had a good week off the tee hitting 73.21% of the fairways (T5), but perhaps his GIR percentage of 58.33% (T32) left him with too much to do to secure his eighth Asian Tour title.
Korean Junghwan Lee has now finished T2, T4 and T2 in the last three editions of the GS Caltex Maekyung Open, and he did a great job keeping bogeys off the card last week. He led the Fewest Bogies or Worse category with only six made for the tournament, along with the winner Mun and fellow Korean Sanghee Lee who finished T7. Lee also placed high in the GIR category with 73.61% ranking sixth and fourth in the Scrambling category with 73.68%.
Baekjun Kim, who leads the Korean PGA Tour Genesis Point Rankings, also had a good week on the greens ranking fifth in Putts per GIR with 1.698.

A strong home challenge is expected at the International Series Japan presented by Moutai this week, some of Japan’s finest are in the field at Caledonian Golf Club – including one of the nation’s hottest properties, Taiga Semikawa.
Semikawa, named after the legendary Tiger Woods, created waves back in 2022 by becoming the first amateur in 95 years to win the Japan Open. In that same standout season, he also secured victories at the Panasonic Open and the Japan Create Challenge on his way to top spot in the world amateur rankings. Since then, as a professional, he has gone on to win the Golf Nippon Series JT Cup and the Kansai Open Golf Championship, both in 2023 – impressive returns for a player still in the early stages of his career, and is currently aged 24.
With Japan’s Ryo Ishikawa, and LIV Golf stars including compatriot Jinichiro Kozuma of Iron Heads GC, Lucas Herbert of the all-Australian team Ripper GC and Caleb Surrat of Legion XIII, playing this week, Semikawa believes it is the perfect place to benchmark his form.
He said: “This is my first time playing in The International Series. I think it will be a great opportunity to compete with the Asian Tour and LIV golf players. I feel The International series is a big because the top players from Asian Tour and LIV golf take part, and this is a wonderful opportunity to compete alongside them.”

Semikawa has not tasted success since 2023 but the golfing prodigy is hoping a change in mindset could help this week in what is the first ever International Series event to be played in Japan..
Summing up his form, he said: “I feel that, compared to then, my mental game is lacking. In 2023 I had a sense that I could win but recently, I haven’t been feeling that way. I need to be confident in my ability to make short putts.”
The old adage ‘beware the wounded golfer’ is one to keep in mind this week, with Semikawa on the road to recovery following a fractured rib.
He is hopeful it won’t impact his game as he prepares for a 7:40am start on the 10th tee on Thursday.
“I had a fracture, but I made my comeback last week,” he revealed. “Although there was still some pain, I managed to push through and finish all four days, which was a big achievement.
“I believe I can make use of that experience and approach this week in better condition than last time.”
Regarding the challenge posed by Caledonian Golf Course, he said: “I have played on this course before during training camps and the Japan Student Championship. I think driving distance is going to be a important, but keeping the ball in the fairway is also very important.”
The ADT Players Championship presented by The R&A will return to the Asian Development Tour (ADT) schedule this season, after its highly successful debut last year – and it will be staged at Luisita Golf & Country Club in the Philippines.
The tournament, won last year by Thailand’s Nopparat Panichphol after a close finish in Cambodia, will be staged from 16-19 October, with a minimum purse of US$100,000.
It is the eighth stop of the season on the ADT, although more tournaments are due to be unveiled, and it will mark the first time the circuit has visited the archipelago in nearly a decade.
The ADT Players Championship presented by The R&A was launched in order to help both the ADT and The R&A achieve their objectives of nurturing raw talent in the region and discovering the stars of tomorrow.
Said Ken Kudo, General Manager, Asian Development Tour: “The first edition of the ADT Players Championship presented by The R&A provided us with a wonderful opportunity to work with the game’s governing body and it was an unqualified success.
“Like The R&A, the Asian Development Tour works at both developmental and elite level, with the ADT Players Championship presented by The R&A a model tournament that helps provide a pathway from one to the other.
“We thank them for their support and guidance plus we also extend our gratitude to Luisita Golf & Country Club and the National Golf Association of the Philippines for their commitment to making this event a success.”
Luisita Golf & Country Club.
The winner of the event will receive an invite to play in the International Series Philippines, being played the following week, at St. Elena Golf Club, 23-26 October.
The 144-player field will be made up of 80 from the ADT, up to 36 from The R&A, and 20 from the Philippine Golf Tour. There will be six amateurs and two invites from the club – which is located in Tarlac City, Central Luzon.
Phil Anderton, Chief Development Officer at The R&A, said: “Establishing clear development pathways for aspiring golfers to reach their full potential in the sport sits at the heart of what we do at The R&A and reflects our support of the Asian Development Tour. We are pleased to see this event being staged in the Philippines, where golf continues to grow in popularity. Thanks to the efforts of the National Golf Association of the Philippines, they are increasingly becoming an important market in the region.”
The ADT last went to the Philippines in 2016, when Filipino Jay Bayron claimed the Aboitiz Invitational.
Bones Floro, Secretary General, National Golf Association of the Philippines: “We are thrilled to welcome the Asian Development Tour back to the Philippines, offering a world-class stage for rising talent and reaffirming our country’s place on the global golfing map.”
Filipino Aldric Chan, who claimed the Lexus Challenge in Vietnam on the ADT in March: “Having an Asian Development Tour event in the Philippines is one of the best things that can happen to help grow the sport locally. And with the support of The R&A it helps us see the potential that the sport has within our community. A lot of great talent is here in the Philippines that will truly benefit from this tournament.”
Nopparat was victorious last year after a gripping end to the tournament. Playing in the second to last group, a fine round saw him finish with a seven- under-par 65 to take the clubhouse lead on 20-under at Angkor Golf Resort – an Asian Tour Destinations venue. Holding a two-shot lead over the rest of the field only Ahmad Baig was in a position to spoil the party. The Pakistani needed a par on the last to force a play-off, but a bogey dashed his hopes.
The next event on the ADT is the Singha Laguna Phuket Open at Laguna Golf Phuket, 22-25 May. Thailand’s Pavit Tangkamolprasert in the defending champion; his win last year taking his tally of titles on the ADT to eight – the most by any on the popular circuit.
The International Series makes its debut in Japan this week – at the International Series Japan presented by Moutai – and two of the Asian Tour’s serial winners, fresh from impressive performances at the weekend, are eager to capitalise on returning to a country they have enjoyed success.
Thailand’s Jazz Janewattananond was named Japan Tour Rookie of the Year in 2019 and the seven-time Asian Tour champion is looking to recreate some of that form here this week, at Caledonian Golf Club, Chiba.
He’s certainly trending in the right direction. The 29-year-old was tied for the lead going into the final round of the 44th GS Caltex Maekyung Open in Korea on Sunday and in with a great shout of making it tournament victory number eight.
On a challenging final day, Jazz had to settle for a tie for second, while home hope Doyeob Mun roared to a sensational three-shot victory with a flawless eight-under round – including six back-nine birdies – on the testing course at Namseoul Country Club.
The T2 is still a positive for the 2022 International Series Morocco champion, who feels there is still a lot more to come this season. He said: “The swing is trending, but just not there yet – it’s not automatic yet. I still have some shots where I don’t feel comfortable, but I know what to work on.
Scott Vincent. Picture courtesy of the Korean Golf Association.
“I haven’t been to Japan in so long. I used to play a full schedule there in 2019, and it is something special. Every golf course is perfectly manicured. You know you’re going to get a good level of golf, and a challenging golf course.
“So I’m looking forward to that, and catching up with some old friends I haven’t seen in a while,” added Jazz, who won the SMBC Singapore Open by two shots from Paul Casey and Yoshinori Fujimoto in 2019 when the event was co-sanctioned by the Asian Tour and the Japan Golf Tour.
Scott Vincent, the 2022 International Series Rankings champion, has also shown great form in the Land of the Rising Sun: he won the Landic Challenge 7 on the Challenge Tour there in 2019, and claimed three victories on the main tour over a 10-month period between 2021 and 2022.
The Zimbabwean finished one shot ahead of Ryo Ishikawa to win the Sansan KBC Augusta in August 2021 before securing a three-shot victory over Tomoharu Otsuki at the ANA Open the following month.
Vincent then secured a play-off win at the Gateway to The Open Mizuno Open in May 2022, part of a remarkable run that culminated in victory at the inaugural International Series England a week later.
That result propelled Vincent to the top of the end-of-year rankings, and a coveted place on the LIV Golf League.
Vincent pictured winning the Landic Challenge 7 on the Challenge Tour in Japan in 2019.
The 32-year-old spent two successful years competing against the world’s best, for the Iron Heads GC team, before narrowly losing his status at the end of last season.
He looked to be getting back to his best on Asian Tour duty in Korea last week, sitting fifth behind Jazz and co-leader Baekjun Kim going into the final round. But a disappointing three bogeys and double on the closing four holes derailed Vincent, and left him T12 overall.
A disappointing finish perhaps, but still something to work on in a country that has brought rich rewards in the past.
Vincent also secured a T9 at the Maezawa Cup in Japan last month, to go with top-10 finishes at International Series India presented by DLF and the season-opening Philippine Open on the Asian Tour.
He said: “Overall I feel like it is moving in the right direction. I’ve been obviously working on it (my game), and sometimes it works out great, sometimes not. But I like where it’s heading, and the feels that I’m creating.
“I am obviously just trying to play the best I can and do the things that I think are going to help. Sometimes that works, sometimes it doesn’t. Right now it feels good – I will just keep trying to work on the things that I’m working on.”
Korean Doyeob Mun, like a bolt from the blue, won the GS Caltex Maekyung Open after a sensational back nine birdie-fest saw him shoot a sizzling bogey-free eight-under-par 63.
Mun, six behind the leaders at the start of the day and playing nine groups ahead of the final pairing, stormed through with six birdies on the second half – including four-in-row from the 11th – to win by three shots from Thailand’s Jazz Janewattananond, plus Koreans Baekjun Kim and Junghwan Lee.
Mun posted his 10-under par total two hours before the final players finished, anxiously waiting to see if he would be caught.
Jazz missed makeable birdie putts on 14 and 15 and later bogeyed the last while Canadian Yonggu Shin birdied 13 and 14 to move one back but then dropped a shot on the 17th, before a catastrophic 10 on 18. He ended in a tie for 12th.

Mun’s run for the title was fast and furious. After making those four successive birdies he was one shot behind Jazz, who had just made the turn. The Korean soon joined Jazz in the lead on nine under after another birdie on 16 before making a birdie on the last for sole possession of first. He hit a majestic second shot on the difficult par-four 18th to six feet to set up one of only three birdies there today. And when Jazz dropped a shot on 13 Mun led by two in the clubhouse. He was hitting balls on the range in case of a play-off before events unfolded in his favour.
“I couldn’t be happier to be on top of the leaderboard in a tournament I’ve always wanted to win,” said Mun, whose home club is Namseoul
“When the birdie putt on 18 went in, I thought I could at least make it to play-off. I talked to my caddie about making sure I made that birdie, and I’m happy that I did.
“The last three holes at Namseoul Country Club are particularly tricky. I focused on playing steady and making par rather than being aggressive. I wasn’t aiming for birdies, just putting the ball in the right position.”
It is his first win on the Asian Tour and fourth on the Korean PGA Tour, as this week’s event is sanctioned with the local body. He last triumphed in Korea in 2022.
Jazz Janewattananond. Picture courtesy of the Korean Golf Association.
The 33-year-old has played regularly on the Asian Tour since 2018, having made it through qualifying school in 2018 and this year, when he placed third. Previously, his best finish on tour came at the Shinhan Donghae Open in 2018, when he was joint fourth, and he also finished in the top five at the Singapore Open in 2019 and 2022.
His 63 was two short of the course record and made a mockery of Namseoul’s reputation for being one of the toughest courses on the circuit.
Carved out of mountainous terrain, its undulating topography, and elevated greens, that are slick and sloping, make it a true test plus a physical challenge to walk. Fortunately, sunshine today replaced the grey skies and drizzle, from earlier in the week.
Despite his brilliant come-from-behind win, Malaysia’s Danny Chia still has the record for most shots gained on the last day. He came from seven behind to win the Taiwan Open in 2002 – when a typhoon played havoc with the scores.
Jazz, who shared the lead at the start of the day with Baekjun Kim, was bidding to become the first overseas player to win this event in 21 years but faded on the back nine, playing it in two over.
He said: “Oh, I mean, it was so hard out there today, it was a grind fest. I mean, I tried to grind as much as I could. I didn’t give up at all at any point. But it was just hard, you know, like I didn’t have my best stuff out there, but overall, I think I finished up well.
Scott Vincent. Picture courtesy of the Korean Golf Association.
“Congrats to Doyeob. I don’t know how he shot eight under par today, but if it wasn’t for him, I would be doing a play-off with another player right now. So overall, good.”
Zimbabwe’s Scott Vincent, two behind at the start of the day and like Jazz looking for his first win since 2022, was in contention for much of the day but finished poorly with a double bogey and three bogeys, carding a 75 to tie for 12th.
The Asian Tour crosses the Sea of Japan next week for the International Series Japan presented by Moutai. The inaugural US$2million event is being played at Caledonian Golf Club, 8-11 May.
Contributions played an important part in a memorable week at the International Series Japan presented by Moutai
Playing tournament golf in Japan is always a memorable experience and at the recently staged International Series Japan presented by Moutai, competitors chose to honour this in the best way possible – by giving back to the community.
A wealth of competitors, including the champion Lucas Herbert from Australia, donated equipment to the Japan High School and Junior High School Golf Association, one of the nation’s leading supporters of grassroots golf.
Golf balls, hats and gloves were all gifted to the association during the week, helping to ensure the country’s up-and-coming golfers have a surplus of quality golf products.
The contributions helped played an important part in an unforgettable week at Caledonian Golf Club, which marked the first time The International Series had visited Japan.
Said Herbert after his win: “I had the pleasure of first coming to play in Japan as an amateur at the start of my career and it’s just a special place. I had some of the best food I have ever had this week, and it’s just been an incredible experience.”

Yuta Sugiura, one of Japan’s rising stars and a two-time winner on the Japan Golf Tour, finished as the leading local player in a tie for second place.
The 23-year-old is an inspiration to the country’s next generation of golfers, including the aspiring golfers at the Japan High School.
“We are so grateful to the Asian Tour and The International Series for these wonderful donations to our students,” said Hisahiko Inoue [main picture with Cho Minn Thant, Commissioner & CEO, Asian Tour], Chairman, Japan High School and Junior High School Golf Association.
“These gifts will be a great incentive to our golfers to try and reach the next level and follow in the footsteps of players like Yuta Sugiura. Golf in Japan continues to be very popular and we are trying to play our part in helping it to grow.”
Five players from Japan finished in the top-10 at the International Series Japan presented by Moutai – including Jinichiro Kozuma, who plays on the LIV Golf League – showcasing the strength in depth of the powerful golfing nation.

Giant real estate company DLF was presenting partner of the International Series India; Chinese beverage maker Moutai presented the International Series Japan; Cambodian conglomerate Royal Group will present the International Series Cambodia, and Bingo Plus will present the International Series Philippines.
Earlier this year saw the second edition of the International Series Macau presented by Wynn, further evidence of the brand’s appeal.
Moutai has also been named as title sponsor of the storied Singapore Open, a legacy event in the region which returns to the Asian Tour calendar after a hiatus of three years.

LIV Golf star Lucas Herbert put on a putting masterclass at Caledonian Golf Club last week
LIV Golf star Lucas Herbert put on a putting masterclass to win the International Series Japan presented by Moutai last week, at Caledonian Golf Club.
The 29-year-old from Australia topped the Putts per Greens in Regulation (GIR) category with 1.531, with Thailand’s Atiruj Winaicharoenchai second on 1.583. Herbert also ranked third in Putts per Round with 26.75, behind only Korean Younghan Song, with 26.25, and Atiruj, on 26.5.
Thanks to his brilliant performance on the greens, Herbert impressively posted under-par scores on 37.5% of the holes, and led both the Most Birdies and Most Eagles categories for the week with 23 birdies and four eagles respectively.
His other stats for the week were also strong: Driving Distance 307.2 yards (10th), Fairways Hit 64.29% (T18), and GIR 68.06 (T35).

Japan’s Yuta Sugiura was very good at keeping bogeys off his scorecard, making only two for the 72 holes and four less than anyone else who made the cut. He also produced solid stats in the Putts per Round and GIR categories with 27.5 (T9) and 72.22% respectively.
Song not only topped Putts per Round but also led both the Putts per Round and Putts per GIR categories after three rounds, and was sixth in Putts per GIR with 1.617.

Australian celebrates ‘away win’ against formidable field at International Series Japan presented by Moutai
Lucas Herbert has moved to the top of The International Series Rankings following his stunning five-shot victory at the International Series Japan presented by Moutai at the weekend.
The Australian, who plays for Ripper GC on LIV Golf, led from the start after a course record-equalling nine-under-par 62 on Thursday at Caledonian Golf Club, and although he was five adrift with three to play on Saturday, he roared to victory thanks to two eagles in his closing three holes which got him a three-way share of the lead going into the final day.
A closing 64 was enough to see off nearest challengers Yuta Sigiura of Japan and Younghan Song of Korea, and the dominant display underlined Herbert’s rich vein of good form this season that has already generated three top-five finishes and three top-20 results in seven LIV Golf League events.
“The strength of the field was very good. I have played in Japan a few times over the years, and the field strength is always good,” said Herbert, who is becoming something of a specialist in the Land of the Rising Sun as his last tournament win was also there, at the ISPS Handa Championship in 2023.
“It’s tricky. It feels like I am playing an away game against these guys on their home turf. Their games are all structured and built to play really well in Japanese courses. So it is tough to beat them at their own game at times.

“That’s why the two wins I have had in Japan have felt quite special, because it feels like winning an away game like in other sports when you are beating these guys on their home venues, against home crowds too.”
Herbert shot up 20 positions to pole on the rankings thanks to the 180 points earned, and he leads the International Series Macau presented by Wynn winner Carlos Ortiz of Mexico and International Series India presented by DLF champion Ollie Schniederjans by 22.95 points, with Bryson DeChambeau and Patrick Reed tied fourth, a further 70 points behind.
American Schniederjans missed both the Macau and Japan dates because of injury, and will be hoping for a return in time for International Series Morocco from 3-6 July.
The winner of The International Series Rankings earns a place on the ensuing season’s LIV Golf League – a lifechanging opportunity on the groundbreaking franchise.

Doyeob Mun secured victory by finishing in the top-10 in four statistics categories
Namseoul Country Club, venue for the GS Caltex Maekyung Open, is always a stern test – especially because of the notoriously difficult greens.
This year was no exception. The conditions were especially tough on Sunday, when strong, gusty winds and firm and fast greens pushed the scoring average up to 73.391, on the par-71 layout.
The par-four 18th hole at Namseoul is always a difficult hole, and even more so with the traditional Sunday pin on the top shelf of the slick two tiered green. After averaging a score of 4.325 in the first three rounds, the hole averaged 4.972 on the final day. One player recorded a sextuple bogey 10, while there were five triples, nine doubles and 35 bogies against only four birdies. Not surprisingly, the 18th ranked as the most difficult hole on the course on Sunday, and was second behind the 16th hole for the week.
However, the champion Doyeob Mun from Korea had no trouble with the 18th on Sunday making a birdie, a feat only three other players matched, and produced a spectacular bogey free eight-under-par 63 in the final round for his first Asian Tour victory. Incredibly, he beat the scoring average on the last day by more than 10 shots, winning by three over the trio of Jazz Janewattananond from Thailand and Koreans Baekjun Kim and Junghwan Lee, after starting the day six shots behind the leaders.
Mun finished joint top in the Fewest Bogies or Worse column with six. He ranked second in Greens in Regulation (GIR) with 76.39%, and he was third in scrambling with 76.47%.

He was also accurate off the tee hitting 73.21% of the fairways and placing T5 in this category. Mun’s other stats for the week were very consistent: Putts per GIR 1.782 (21st), Putts per Round 29.5 (T21), Driving Distance 293 yards (18th).
Seven-time Asian Tour winner Jazz had a good week on and around the greens and he ranked second in Putts per Round with 26.75, T8 in Putts per Green with 1.714 and fifth in Scrambling with 73.33%. He also had a good week off the tee hitting 73.21% of the fairways (T5), but perhaps his GIR percentage of 58.33% (T32) left him with too much to do to secure his eighth Asian Tour title.
Korean Junghwan Lee has now finished T2, T4 and T2 in the last three editions of the GS Caltex Maekyung Open, and he did a great job keeping bogeys off the card last week. He led the Fewest Bogies or Worse category with only six made for the tournament, along with the winner Mun and fellow Korean Sanghee Lee who finished T7. Lee also placed high in the GIR category with 73.61% ranking sixth and fourth in the Scrambling category with 73.68%.
Baekjun Kim, who leads the Korean PGA Tour Genesis Point Rankings, also had a good week on the greens ranking fifth in Putts per GIR with 1.698.

International Series Japan presented by Moutai starts Thursday at Caledonian Golf Club
A strong home challenge is expected at the International Series Japan presented by Moutai this week, some of Japan’s finest are in the field at Caledonian Golf Club – including one of the nation’s hottest properties, Taiga Semikawa.
Semikawa, named after the legendary Tiger Woods, created waves back in 2022 by becoming the first amateur in 95 years to win the Japan Open. In that same standout season, he also secured victories at the Panasonic Open and the Japan Create Challenge on his way to top spot in the world amateur rankings. Since then, as a professional, he has gone on to win the Golf Nippon Series JT Cup and the Kansai Open Golf Championship, both in 2023 – impressive returns for a player still in the early stages of his career, and is currently aged 24.
With Japan’s Ryo Ishikawa, and LIV Golf stars including compatriot Jinichiro Kozuma of Iron Heads GC, Lucas Herbert of the all-Australian team Ripper GC and Caleb Surrat of Legion XIII, playing this week, Semikawa believes it is the perfect place to benchmark his form.
He said: “This is my first time playing in The International Series. I think it will be a great opportunity to compete with the Asian Tour and LIV golf players. I feel The International series is a big because the top players from Asian Tour and LIV golf take part, and this is a wonderful opportunity to compete alongside them.”

Semikawa has not tasted success since 2023 but the golfing prodigy is hoping a change in mindset could help this week in what is the first ever International Series event to be played in Japan..
Summing up his form, he said: “I feel that, compared to then, my mental game is lacking. In 2023 I had a sense that I could win but recently, I haven’t been feeling that way. I need to be confident in my ability to make short putts.”
The old adage ‘beware the wounded golfer’ is one to keep in mind this week, with Semikawa on the road to recovery following a fractured rib.
He is hopeful it won’t impact his game as he prepares for a 7:40am start on the 10th tee on Thursday.
“I had a fracture, but I made my comeback last week,” he revealed. “Although there was still some pain, I managed to push through and finish all four days, which was a big achievement.
“I believe I can make use of that experience and approach this week in better condition than last time.”
Regarding the challenge posed by Caledonian Golf Course, he said: “I have played on this course before during training camps and the Japan Student Championship. I think driving distance is going to be a important, but keeping the ball in the fairway is also very important.”
The tournament will be staged at Luisita Golf & Country Club in the Philippines from 16-19 October
The ADT Players Championship presented by The R&A will return to the Asian Development Tour (ADT) schedule this season, after its highly successful debut last year – and it will be staged at Luisita Golf & Country Club in the Philippines.
The tournament, won last year by Thailand’s Nopparat Panichphol after a close finish in Cambodia, will be staged from 16-19 October, with a minimum purse of US$100,000.
It is the eighth stop of the season on the ADT, although more tournaments are due to be unveiled, and it will mark the first time the circuit has visited the archipelago in nearly a decade.
The ADT Players Championship presented by The R&A was launched in order to help both the ADT and The R&A achieve their objectives of nurturing raw talent in the region and discovering the stars of tomorrow.
Said Ken Kudo, General Manager, Asian Development Tour: “The first edition of the ADT Players Championship presented by The R&A provided us with a wonderful opportunity to work with the game’s governing body and it was an unqualified success.
“Like The R&A, the Asian Development Tour works at both developmental and elite level, with the ADT Players Championship presented by The R&A a model tournament that helps provide a pathway from one to the other.
“We thank them for their support and guidance plus we also extend our gratitude to Luisita Golf & Country Club and the National Golf Association of the Philippines for their commitment to making this event a success.”
Luisita Golf & Country Club.
The winner of the event will receive an invite to play in the International Series Philippines, being played the following week, at St. Elena Golf Club, 23-26 October.
The 144-player field will be made up of 80 from the ADT, up to 36 from The R&A, and 20 from the Philippine Golf Tour. There will be six amateurs and two invites from the club – which is located in Tarlac City, Central Luzon.
Phil Anderton, Chief Development Officer at The R&A, said: “Establishing clear development pathways for aspiring golfers to reach their full potential in the sport sits at the heart of what we do at The R&A and reflects our support of the Asian Development Tour. We are pleased to see this event being staged in the Philippines, where golf continues to grow in popularity. Thanks to the efforts of the National Golf Association of the Philippines, they are increasingly becoming an important market in the region.”
The ADT last went to the Philippines in 2016, when Filipino Jay Bayron claimed the Aboitiz Invitational.
Bones Floro, Secretary General, National Golf Association of the Philippines: “We are thrilled to welcome the Asian Development Tour back to the Philippines, offering a world-class stage for rising talent and reaffirming our country’s place on the global golfing map.”
Filipino Aldric Chan, who claimed the Lexus Challenge in Vietnam on the ADT in March: “Having an Asian Development Tour event in the Philippines is one of the best things that can happen to help grow the sport locally. And with the support of The R&A it helps us see the potential that the sport has within our community. A lot of great talent is here in the Philippines that will truly benefit from this tournament.”
Nopparat was victorious last year after a gripping end to the tournament. Playing in the second to last group, a fine round saw him finish with a seven- under-par 65 to take the clubhouse lead on 20-under at Angkor Golf Resort – an Asian Tour Destinations venue. Holding a two-shot lead over the rest of the field only Ahmad Baig was in a position to spoil the party. The Pakistani needed a par on the last to force a play-off, but a bogey dashed his hopes.
The next event on the ADT is the Singha Laguna Phuket Open at Laguna Golf Phuket, 22-25 May. Thailand’s Pavit Tangkamolprasert in the defending champion; his win last year taking his tally of titles on the ADT to eight – the most by any on the popular circuit.
The International Series makes its debut in Japan this week – at the International Series Japan presented by Moutai
The International Series makes its debut in Japan this week – at the International Series Japan presented by Moutai – and two of the Asian Tour’s serial winners, fresh from impressive performances at the weekend, are eager to capitalise on returning to a country they have enjoyed success.
Thailand’s Jazz Janewattananond was named Japan Tour Rookie of the Year in 2019 and the seven-time Asian Tour champion is looking to recreate some of that form here this week, at Caledonian Golf Club, Chiba.
He’s certainly trending in the right direction. The 29-year-old was tied for the lead going into the final round of the 44th GS Caltex Maekyung Open in Korea on Sunday and in with a great shout of making it tournament victory number eight.
On a challenging final day, Jazz had to settle for a tie for second, while home hope Doyeob Mun roared to a sensational three-shot victory with a flawless eight-under round – including six back-nine birdies – on the testing course at Namseoul Country Club.
The T2 is still a positive for the 2022 International Series Morocco champion, who feels there is still a lot more to come this season. He said: “The swing is trending, but just not there yet – it’s not automatic yet. I still have some shots where I don’t feel comfortable, but I know what to work on.

“I haven’t been to Japan in so long. I used to play a full schedule there in 2019, and it is something special. Every golf course is perfectly manicured. You know you’re going to get a good level of golf, and a challenging golf course.
“So I’m looking forward to that, and catching up with some old friends I haven’t seen in a while,” added Jazz, who won the SMBC Singapore Open by two shots from Paul Casey and Yoshinori Fujimoto in 2019 when the event was co-sanctioned by the Asian Tour and the Japan Golf Tour.
Scott Vincent, the 2022 International Series Rankings champion, has also shown great form in the Land of the Rising Sun: he won the Landic Challenge 7 on the Challenge Tour there in 2019, and claimed three victories on the main tour over a 10-month period between 2021 and 2022.
The Zimbabwean finished one shot ahead of Ryo Ishikawa to win the Sansan KBC Augusta in August 2021 before securing a three-shot victory over Tomoharu Otsuki at the ANA Open the following month.
Vincent then secured a play-off win at the Gateway to The Open Mizuno Open in May 2022, part of a remarkable run that culminated in victory at the inaugural International Series England a week later.
That result propelled Vincent to the top of the end-of-year rankings, and a coveted place on the LIV Golf League.
Vincent pictured winning the Landic Challenge 7 on the Challenge Tour in Japan in 2019.
The 32-year-old spent two successful years competing against the world’s best, for the Iron Heads GC team, before narrowly losing his status at the end of last season.
He looked to be getting back to his best on Asian Tour duty in Korea last week, sitting fifth behind Jazz and co-leader Baekjun Kim going into the final round. But a disappointing three bogeys and double on the closing four holes derailed Vincent, and left him T12 overall.
A disappointing finish perhaps, but still something to work on in a country that has brought rich rewards in the past.
Vincent also secured a T9 at the Maezawa Cup in Japan last month, to go with top-10 finishes at International Series India presented by DLF and the season-opening Philippine Open on the Asian Tour.
He said: “Overall I feel like it is moving in the right direction. I’ve been obviously working on it (my game), and sometimes it works out great, sometimes not. But I like where it’s heading, and the feels that I’m creating.
“I am obviously just trying to play the best I can and do the things that I think are going to help. Sometimes that works, sometimes it doesn’t. Right now it feels good – I will just keep trying to work on the things that I’m working on.”
Korean goes on birdie spree on the back nine shooting a sizzling bogey-free eight-under-par 63
Korean Doyeob Mun, like a bolt from the blue, won the GS Caltex Maekyung Open after a sensational back nine birdie-fest saw him shoot a sizzling bogey-free eight-under-par 63.
Mun, six behind the leaders at the start of the day and playing nine groups ahead of the final pairing, stormed through with six birdies on the second half – including four-in-row from the 11th – to win by three shots from Thailand’s Jazz Janewattananond, plus Koreans Baekjun Kim and Junghwan Lee.
Mun posted his 10-under par total two hours before the final players finished, anxiously waiting to see if he would be caught.
Jazz missed makeable birdie putts on 14 and 15 and later bogeyed the last while Canadian Yonggu Shin birdied 13 and 14 to move one back but then dropped a shot on the 17th, before a catastrophic 10 on 18. He ended in a tie for 12th.

Mun’s run for the title was fast and furious. After making those four successive birdies he was one shot behind Jazz, who had just made the turn. The Korean soon joined Jazz in the lead on nine under after another birdie on 16 before making a birdie on the last for sole possession of first. He hit a majestic second shot on the difficult par-four 18th to six feet to set up one of only three birdies there today. And when Jazz dropped a shot on 13 Mun led by two in the clubhouse. He was hitting balls on the range in case of a play-off before events unfolded in his favour.
“I couldn’t be happier to be on top of the leaderboard in a tournament I’ve always wanted to win,” said Mun, whose home club is Namseoul
“When the birdie putt on 18 went in, I thought I could at least make it to play-off. I talked to my caddie about making sure I made that birdie, and I’m happy that I did.
“The last three holes at Namseoul Country Club are particularly tricky. I focused on playing steady and making par rather than being aggressive. I wasn’t aiming for birdies, just putting the ball in the right position.”
It is his first win on the Asian Tour and fourth on the Korean PGA Tour, as this week’s event is sanctioned with the local body. He last triumphed in Korea in 2022.

The 33-year-old has played regularly on the Asian Tour since 2018, having made it through qualifying school in 2018 and this year, when he placed third. Previously, his best finish on tour came at the Shinhan Donghae Open in 2018, when he was joint fourth, and he also finished in the top five at the Singapore Open in 2019 and 2022.
His 63 was two short of the course record and made a mockery of Namseoul’s reputation for being one of the toughest courses on the circuit.
Carved out of mountainous terrain, its undulating topography, and elevated greens, that are slick and sloping, make it a true test plus a physical challenge to walk. Fortunately, sunshine today replaced the grey skies and drizzle, from earlier in the week.
Despite his brilliant come-from-behind win, Malaysia’s Danny Chia still has the record for most shots gained on the last day. He came from seven behind to win the Taiwan Open in 2002 – when a typhoon played havoc with the scores.
Jazz, who shared the lead at the start of the day with Baekjun Kim, was bidding to become the first overseas player to win this event in 21 years but faded on the back nine, playing it in two over.
He said: “Oh, I mean, it was so hard out there today, it was a grind fest. I mean, I tried to grind as much as I could. I didn’t give up at all at any point. But it was just hard, you know, like I didn’t have my best stuff out there, but overall, I think I finished up well.

“Congrats to Doyeob. I don’t know how he shot eight under par today, but if it wasn’t for him, I would be doing a play-off with another player right now. So overall, good.”
Zimbabwe’s Scott Vincent, two behind at the start of the day and like Jazz looking for his first win since 2022, was in contention for much of the day but finished poorly with a double bogey and three bogeys, carding a 75 to tie for 12th.
The Asian Tour crosses the Sea of Japan next week for the International Series Japan presented by Moutai. The inaugural US$2million event is being played at Caledonian Golf Club, 8-11 May.
