India’s Jyoti Randhawa charged ahead in the second round of the Chiangmai Golf Classic on Friday with a seven-under-par 65, claiming a one-shot lead.

The eight-time Asian Tour winner birdied the last two holes for an 11-under-par 133 total, one shot ahead of Thailand’s Thanyakon Khrongpha in the $US750,000 ($A812,000) Asian Tour event.

Australia’s Scott Barr is four shots off the lead at seven under in a tie for third with India’s Rashid Khan.

Randhawa, whose last Asian Tour victory was the 2009 Thailand Open, said it was the best he had played “in a long, long time”.

“I fired on all cylinders today. My driving, second shots and putting were good,” said the 42-year-old in a statement released by organisers.

The 2013 PGA Championship winner Jason Dufner is at six under.

“I struggled with my putter a little bit because of a combination of bad speed. When you can’t judge the speed, you kind of second guess on the greens,” said American Dufner.

The major winner is making his Thai debut and playing for a fourth straight week after recovering from a neck injury.
