Thailand’s Nirat had seven birdies and a single bogey in his round, while China’s Liang had eight gains and two dropped shots – the highlight a 25-foot birdie putt at the 17th.
Both players advanced to 12-under-par at Jaypee Greens Golf & Spa Resort to move two clear of Thailand’s Chawalit Plaphol and Scotland’s David Drysdale, as overnight leader Chinnarat Phadungsil had a very different experience on the back nine.
“I have played some of my best golf this week and I managed to hole several long putts,” said Liang, whose victory came at the 2007 Singapore Masters.
“I’ve learnt to be patient and my playing experience from all over the world has taught me well. There are two more rounds to go and, hopefully, I can be atop the leaderboard like today.”
Nirat was pleased to be top of the leaderboard, but also praised the performance of his compatriots Plaphol and Phadungsil.
“We’ve got many good players from Thailand as you can tell from the leaderboard,” he said.
“Chawalit just won his fourth Asian Tour title in Myanmar and we saw what Chinnarat can do yesterday. He didn’t repeat that performance today but I’m sure he’ll bounce back during the weekend. This course also favours us as it’s long and we’ve many long hitters.”
