BANGKOK, 28 Nov 2014 (AFP) - Five-time Asia Tour winner Lahiri couldn't quite match his previous days' form when he stormed off the starting blocks with an impressive seven-under-par 65.
But it was enough to keep him two shots ahead of Australia's Andrew Dolt and Thailand's Jakraphan Premsirigorn in the $500,000 event with a 12-under-par 132 at the Singha Park Khon Kaen Golf Club.
Chowrasia posted 71 to slip to tied-fifth with Australia's Adam Groom on 136 while local hero Thaworn Wiratchant, a comparative veteran at 47-years-old, took fourth place on 135.
Thaworn, who holds an unprecedented 17 titles on the Asian Tour, laughed off any suggestion age might hold him back from notching up a few more victories.
"Who says I'm old? Still young boy," he said, according to a statement put out by organisers. "I'm still enjoying my game every day and that's important. I love my golf and that's what keeps me going which includes trying to get another win again this week."
Lahiri said he felt comfortable at the top but admitted he couldn't rest easy over the coming days.
"I'm happy with the way I'm playing. It wasn't quite as good as it was yesterday but I'm still feeling comfortable on the golf course and the position I'm in," he said.
