Hua Hin, December 4 : Chapchai Nirat showed his class in testing conditions to storm to a six-stroke victory in the 2016 Thongchai Jaidee Foundation event in Hua Hin.

Staying four shots behind overnight leader Peradol Panyathanasedh by four shots at the start of final round, Chapchai put a brilliant seven-under 65 with eight birdies against a lone bogey to win at the par-72 Black Mountain Golf Club. The Phisanuloke native finished at a 12-under 276 total, six shots ahead of runner-up Sorachut Hansapiban (70).

Peradol, 27, who was seeking his first win in six years, had a nightmarish final day in Hua Hin as he dropped to third on five-under 283 after trading three birdies with five bogeys and a double bogey.

The 33-year-old Chapchai said he had not targeted the title because he was well behind the leader after three rounds. However, being a big hitter gave him a massive advantage in windy conditions on the final day.

"Because of the windy conditions, I tried not to make mistakes and give myself more chances here. I succeeded because I am a big hitter," said Chapchai, who plays regularly on the Japan tour.

"In fact, my target here was only a top-five finish."

Chapchai took home 700,000 baht for his win. 

Defending champion Kiradech Aphibarnrat (71) shared fourth spot with Pannakorn Uthaipas (73) on 284 at the four-million-baht tournament, co-sanctioned by both All Thailand Golf Tour and Asian Development Tour. 

Micah Lauren Shin of the US posted a 68 for a three-under 285 to tie for sixth with amateur Atiruj Winaicharoenchai (70).

Settee Prakongvech had seven birdies and two bogeys for a 67 to share eighth with Chanachok Dejpiratanongkol (68), Raththee Sirithanakunsak (72), Janne Kaske (72) and Kasidit Lepkurte (76) on two-under 286.

Nick Sherwood of the US shot a 69 with four birdies and one bogey for an even-par 288, the same as Gavin Green of Malaysia (71) and Pattaraphol Khanthacha (71). Johan Edfors of Sweden, who won the Black Mountain Masters here in 2009, finished 17th on 289 following a 69.
