Udorn Duangdecha has catapulted himself into the outright lead at the Thailand Open with a remarkable 12-under-par 60 in his second round on Friday with a host of Australians in the hunt at the halfway stage of the tournament.
Matthew Griffin is the best of the Aussies in second place at 11-under, closely followed by Liang Wenchong at 10-under at the OneAsia tour event.
The highest-ranked Chinese player in the world, Wenchong hit a record-low round at the USPGA Championship at Whistling Straits earlier this month, but it was Duangdecha's turn to make headlines at the Burapha Golf Club.
The Thai national sunk seven birdies to go out in a stunningly low 29 before backing it up with five more birdies on the way in, finishing in the lead without dropping a single shot.
"Everything went to plan today. In the first round I tried too hard. I told myself to relax and it all came together. I was not nervous at all. I knew what I had to do," he said.
Giffin and Wenchong kept in touch with the hotshot local with second rounds of seven-under and five-under respectively.
Griffin, ranked the No.3 amateur in the world before turning professional in 2008, did not drop a shot as he bids for his first big breakthrough win.
"I played really well and kept the ball in place nicely," he said.
"I have been putting myself into good positions in tournaments for a while but have not been able to finish off the job. I am trying to learn to relax more and that’s my plan for the weekend."
"It will take good attacking golf and low scores to win this."
Terry Pilkadaris is in a group of three players tied for fourth at nine-under, but the Australian may be distracted going into Saturday's round after being told he had been suspended by the rival Asian Tour for non-payment of fines.
Compatriot Brad Kennedy is also at nine-under, one shot clear of another three Aussies Andre Stolz, Stephen Allan and Michael Wright in seventh place.
Neven Basic is not without a chance at six-under with Mitchell Brown, David Bransdon and Kiwi Gareth Paddison a further shot back.
