Chan Shih-chang secured his first European Tour title with a final-round 67 at the King's Cup in Thailand.
Chan, from Taiwan, was the overnight leader and extended his advantage to finish two strokes clear on 12 under for the tournament.
He picked up six birdies on the day, three within the first five holes, but added bogeys at seven, nine and 16.
The 30-year-old began on day one by shooting one over but took control with a flawless 63 on Saturday and never looked like loosening that grasp.
Chan's compatriot Lin Wen-tang came in second, shooting 66 including six birdies.
Danthai Boonman gave the Thai fans something to cheer, claiming a share of third place alongside Englishman Mark Foster. Foster was undone by successive bogey fives at the fourth and fifth holes, but picked up three shots on the back nine.
