American golfer Lexi Thompson won the Honda LPGA Thailand title after firing a final round four-under-par 68 to win by six strokes ahead of In Gee Chun of South Korea on Sunday.
Thompson was in hot form the whole four days to end on a combined total of 274.
Chun started Sunday's final round four shots behind and challenged early with birdies on her first three holes to be one shot off Thompson, but she threw it all away with four bogeys and a double bogey at the par four, 17th hole.
Chun finished her final round on a two-under par 70 in second place at 14-under.
Tied for third was American Jessica Korda and defending champion Amy Yang at 13-under.
Japan's Haru Nomura and Chella Choi of South Korea ran out the top-5 at 11-under.
The 21-year-old Thompson holed birdie putts on the sixth and eighth then dropped a shot on the par-four ninth. An eagle on the par five 10th saw her at 19-under and then a further birdie on the 15th put her on 20-under from where she was untouchable.
After her win, Thompson said she had a very good day on the course and felt very solid.
“Yeah, it was a good day out there, very solid,” said Thompson. “I just made sure I had fun out there and stayed positive.
"I missed a putt on the first hole which got me down a little bit, but I tried to stay positive going into the next hole and fire at pins like I did the first day.”
“I think it’s all a matter of me getting comfortable on the golf course and just having fun with my caddie Benji in between shots and just keeping myself relaxed,” said Thompson.
“I know where my game’s at right now. But I also know there are a lot of great players out there, so I have to focus on myself.”
