Thailand’s Kosuke Hamamoto held his nerve and secured victory in the ADT All Thailand Partnership Trophy on Sunday, his clubhouse lead of 13 under was enough to win despite finishing with five of the leading groups still out on the course.

Starting the day in 12th place on seven under par, Kosuke opened with five birdies in his front nine, and once play restarted after several delays due to rain and lightning storms, he just needed to pick up one more shot on his back nine to keep his nose in front.

In second place, Settee Prakongvech also shot a six-under-par 65 but had to settle for finishing one shot back at 12 under with fellow Thais Witchayapat Sinsrang and Waris Manthorn. Waris, who led the first two rounds at the Phoenix Gold Golf and Country Club in Pattaya, was in contention during the final day but a bogey on the last hole denied him a chance at a playoff.
