'It was a nice finish. I hit a good lob-wedge that skipped into the hole,' said Wiratchant. 'It was a long day. I had to come back to finish my first round this morning and had six holes to play. I got up at 5:00 a.m. and I'm feeling a bit tired now. But it is good to be at the top of the leaderboard and I'll do my best on the weekend.'
Colsaerts got off to a hot start with birdies at the first, fourth and fifth to quickly move to 9-under. The Belgium native closed a stellar front nine with birdies at the seventh and ninth.

'I'm just really pleased with the way I played today,' said Colsaerts. 'Any week is good for me to play well as I will only have 15 tournaments this year with my category. If I can get some good results or win a tournament, I can get back on the main tour. That's my goal, to win something.'
