Justin Thomas secured his first PGA Tour title on Sunday with a one-shot victory over Adam Scott in the CIMB Classic at Kuala Lumpur Golf Club.
The 22-year-old from Kentucky entered the final round tied for top spot with Brendan Steele.
He then surged clear on his own in Malaysia courtesy of a six-under 66 final round which included birdies at the 15th, 16th and 17th holes.
Thomas, who posted a course-record 61 on Friday to take the halfway lead, finished with a four-round total of 26 under par.
Thomas - needing a par on the final hole to ensure victory - made things tricky for himself when he sent a 25-foot birdie putt five feet past the hole.
He kept his cool to close out the triumph and finish one shot ahead of former world number one Scott.
"It's tough to win,” he said.
"Look at guys like Rickie (Fowler). He's done pretty well for himself and it took him a while to win too.
"I understand we're in a sport where your winning percentage isn't in your favour. I've put myself there a bunch.
“I just need to keep doing so, and moments like this can happen."
The success lifted the University of Alabama graduate to number one in the fledgling 2015-16 FedExCup standings, three events into the campaign.
Former Masters champion Scott burst into contention with a flawless final round of 63 which included seven birdies and an eagle, but fell just short.
Steele (68) had to settle for a share of third place alongside fellow American Kevin Na (67).
