Scott Hend has two stroke lead after the third round of the True Thailand Classic on Saturday.
The Australian – who was tied at the top of the leaderboard at the hallway stage – carded a two under 70 at Black Mountain Golf Club to leave him on 14 under par for the tournament, two shots ahead of first round leader Peter Uihlein.
Two birdies, including a wonderful chip in on the 15th, in the last four holes saw Hend move two clear of the field.
"It was a good grind," the 42-year-old told europeantour.com after the round.
"Out of ten, I felt like two out of ten, felt really tired, no energy. I knew it was going to be a tough day, very windy, so I’m very pleased.
"When you're actually here, you've got to try to enjoy it and embrace it. It's not very often you get a chance to lead a tournament on a Saturday night, let alone on a Sunday."
Turning his thoughts towards the final round on Sunday, Hend was rather philosophical.
"It's just another round of golf for me tomorrow," he added.
"It's a long season. We practise for a result, we practise to try and get a win, we try to get ourselves in this position to have a win. If you're not in this position, you get upset with yourself."
Further down the leaderboard and three shots off the pace were Thomas Pieters and Pelle Edberg on 11 under.
