Ryan Moore retained the Malaysia Classic with a three-shot win at the co-sanctioned PGA and Asian Tour event.
The American, 31, made eight birdies in a final-day 67 to finish 17-under-par.
Gary Woodland, who finished second to Moore last year, was again runner-up at the Kuala Lumpur Golf and Country Club, with Kevin Na and Sergio Garcia.
Lee Westwood, seeking a unique double having won the Malaysian Open on the same course on the European Tour in April, was eight adrift in joint 13th.
The 41-year-old Englishman, who had a hole-in-one in round two, had six birdies in a final-day 68.
Moore birdied three of the final four holes with his slow, deliberate swing working well, and is the first player to successfully to defend a title on the PGA Tour since Tiger Woods at the Arnold Palmer Invitational, in 2012 and 2013.
"It was incredible to finish the way I did coming down those last few holes," said Moore, who has now won four PGA tournaments.
"I like to tell myself all the time that 'I am a closer. Let's just do what we can, hit good shots and let's close this thing' and I was able to do that."
He had shared the overnight lead with Na, who birdied three of the first four holes to take a two-stroke advantage.
But Na dropped a shot at the 13th, and after several birdie chances stayed out, he hit his ball into a palm tree at the 17th, which resulted in a double bogey.
Woodland had moved within a shot of the lead after six birdies in his opening 15 holes but saw a birdie chance spin out of the cup at the 16th, then missed another opportunity at the last, followed by the short return putt.
Garcia carded five birdies in a round of 69, but a double bogey seven at the 10th disrupted his challenge for a ninth PGA Tour title, and first since 2012.
