Adam Scott carded four birdies in a five-hole span as part of a torrid comeback that gave him his second consecutive PGA Tour victory.
Scott's rousing finish on the back nine highlighted a 3-under 69 during Sunday's final round as he finished with a one-shot victory over Bubba Watson in the World Golf Championships-Cadillac Championship at Doral, Fla.
Scott completed the tournament at 12-under 276 to outlast Watson, who shot a final-round 68 at Trump National Doral. Rory McIlroy (74 on Sunday) and Danny Willett (69) finished two shots back.
Scott, 35, began the two-week run of victories with a one-shot win over Sergio Garcia at last week's Honda Classic.
"I can't believe I've won back-to-back weeks," Scott said. "To win a World Golf Championship is huge again."
Scott trailed by six shots with 13 holes remaining and began his comeback with birdies on Nos. 6 and 8. Then he cranked it up another notch on the back nine with birdies on four of the first five holes.
Scott's strong play, which earned him $1.62 million, occurred on a day in which presidential candidate Donald Trump paid a visit to the course he owns.
Trump arrived via helicopter and greeted fans while driving around on a golf cart.
The PGA has plans to meet with Trump soon to discuss the future of the event, as General Motors' sponsorship agreement ran out with this year's event.
It was another close call for Watson, who has finished second or third at Doral in four of the past five years.
His attempt to win was sabotaged by a bogey on the par-4 14th hole.
"I gave it a good effort," Watson said. "What I'm working on in my head is working out. Right now, I've got the energy and the mindset to play some decent golf, so very positive, very happy about the week and what took place."
McIlroy entered the final round with a three-shot lead but managed just one birdie -- on No. 16 -- to go with three bogeys.
