Amarin Kraivixien made great strides up the leaderboard with a 65 today to vault into a shared lead going into the final round of the Asian Development Tour / All Thailand Partnership in Phuket.

Amarin, who shared the low round of the day with Natipong Srithong at Red Mountain Golf Course, holds the joint lead with compatriot Kammalas Namuangruk (66).

“I was surprised with my round today,” he said after finishing up. “I had a fever last night. Felt better this morning but really wasn’t expecting much. I just wanted to keep myself cool with a cold towel.”

As the THB3 million tournament heads into its final day on the ADT’s first visit to the Phuket course, the narrow fairways and sloping greens required extra attention from players.

“My concentration level today was exceptional, I think that helped a lot,” Amarin explained after his bogey-free round.

“I holed a 30-footer for birdie on the first and that gave me a good momentum into the round. Made a couple of six footers for pars too. Not dropping a shot out there kept me going and I’m really pleased with the way I played today.”

Kammalas, with two dropped shots on the back nine, had to fight to keep pace after holding the early lead during the day.

“I putted really well today,” he explained. “I got excited after starting the round with four straight birdies and just kept it going out there.

“It started raining after I made the turn and I lost a bit of momentum but happy to still cap a good round to grab a share of the lead.”

In third place on 12 under, Waris Manthorn (68) of Thailand holds a two shot advantage over fellow Thai Tawit Polthai (67)in fourth.

Chi Huang (67)of Chinese Taipei shares fifth spot with Thailand’s Itthipat Buranatanyarat (66) and overnight leader Kosuke Hamamoto (72).

In eighth place are Thailand’s Natipong Sirithong (65) and Poosit Supupramai (69), followed by Angelo Que (67) of the Philippines in 10th spot on seven under par.

Panat Bodhidatta (67), Sangchai Kaewcharoen (70) Panuphol Pittayarat (73) and first round leader Warun Ieamgaew (71) are an all-Thai group sharing 11th place.

Thailand’s Kenny Lem, who made the cut on the number after Friday’s round, had the bonus of a hole-in-one on the third hole, jarring his eight iron from 155 yards.

The ADT / All Thailand Partnership tournament, a co-sanctioned event by the Asian Development Tour and the All Thailand Golf Tour, is one of two ADT events scheduled for May, with the THB4 million Singha Laguna Phuket Open being held at Laguna Golf Phuket from May 9-12.

Play continues for the final day at Red Mountain, with the first flight off at 7.10am local time and the leading group of Waris, Kammalas and Amarin teeing off at 8.50am.
