Thongchai Jaidee is optimistic of claiming the BMW Masters title on Sunday if he maintains the high standard he has set so far this week as he prepares to take a one-shot lead into the final round.
Jaidee carded a six-under 66 on Saturday - his best round of the week - to move to the top of the leaderboard at 15-under at the Lake Malaren Golf Club.
Lucas Bjerregaard held a three-shot lead at the halfway mark, but a third round of 70 ensured he dropped back to joint-second along with An Byeong-hun and Sergio Garcia.
Jaidee, eyeing his second European Tour win of the season, made five birdies on the front nine and another two on the stretch before his only blemish came with a bogey at 18.
The 46-year-old Thai is determined to get the job done on Sunday and potentially rise to as high as third in the Race to Dubai standings.
"If I play well like this and keep performing like this, I have a good chance. But golf, you never know what you're feeling tomorrow." he said.
"Tomorrow is a very big day. My iron play, I think that's the key, and putting. Tomorrow I'm going to play my own game.
"I played well, we hit a lot of greens. I think today we putted well.
"I think my game plan this week is good. I've hit irons well, I'm working on putting and that's what gave me very good confidence for today. Six under is a very good score."
South Korean An put the disappointment of going round in 71 on Friday behind him by carding a bogey-free 66, while Garcia birdied four of the last six holes to put himself firmly in contention.
Bjerregaard had started with back-to-back rounds of 66, but had to settle for a two-under 70, while a fine round of 64 from Kristoffer Broberg moved him to 13-under.
Fellow Swede Henrik Stenson, American Patrick Reed and Englishman Ian Poulter are among five players tied for sixth, three shots off the lead.
