Amy Yang secured a two-shot victory at the Honda LPGA Thailand after a fascinating final-round contest with Stacy Lewis, while Beatriz Recari set a course record.
Lewis led Yang by just one stroke heading into Sunday's play, but it was the latter who earned the second LPGA Tour title of her career thanks to a three-under par 69 at the Siam Country Club in Chonburi.
Recari also provided a late charge with a stunning nine-under-par 63 that set a new marker for the course, but she fell three shots short.
South Korean Yang made her move early by carding three birdies in the opening seven holes, before a huge putt at the 10th saw her pick up another shot to move two strokes clear.
It appeared as though the momentum had swung at the 14th, though, as Yang bogeyed and Lewis birdied to tie it up atop the leaderboard at 15 under.
However, Lewis' work was undone at the next hole and she struggled to a double bogey after finding herself in trouble, a birdie for Yang putting her three clear.
A bogey at 16 proved a mere blip for Yang who hung on to take victory with an overall score of 15 under, while a couple of pars to finish for Lewis saw her end level par for the round.
The faltering end meant that Lewis was caught by Yani Tseng and Mirim Lee on 13 under for the tournament in a three-way tie for second.
Recari's round included 11 birdies, a couple of bogies doing little to dampen a brilliant card, and the Spaniard finished in a tie for fifth.
