Scott Hend of Australia shot a final-round 68 to beat Piya Swangarunporn of Thailand by a stroke to win the Thailand Classic at the Black Mountain Golf Course on Sunday.
Hend rolled in five birdies against one bogey for an overall total of 18-under-par 270 to win his second European Tour event.
The Australian, who holed a crucial birdie on the 17th hole to take the lead, says "I'm very proud to win this title."
The win marked the 43-year-old golfer's second Asian Tour title in Thailand after the 2013 Chiang Mai Classic and the eighth on the Asian Tour.
Piya, 32, had his best result on the Asian Tour after he shot a tournament record 63 on Sunday that included seven birdies and an eagle on the 10th to finish one back.
