Adam Scott mounted a brilliant comeback to hold off the challenge of Bubba Watson and win a second World Golf Championships title at the WGC - Cadillac Championship.
The Australian began the day three shots behind overnight leader Rory McIlroy and trailed by six in the early stages at Trump National Doral after two double-bogeys in his first five holes.
Some stunning approach play then produced six birdies in the next nine holes as he hit the front, and the 2011 WGC - Bridgestone Invitational champion held his nerve up the stretch to finish at 12 under and beat Watson by one shot.
Englishman Danny Willett was then at ten under after an excellent closing 69, with the Omega Dubai Desert Classic champion only seeing his chance of victory disappear after finding the water off the tee on the last.
Race to Dubai champion McIlroy also finished on ten under after a 74.
There was drama for Scott on the last when his second shot finished inside the hazard line but not in the water, and he had to get up and down with the ball below his feet and sink a six-foot putt to take the crown.
"I made a couple of horrible errors on the front nine but you can't give up hope and I thought if I can get a couple of birdies before the turn, maybe a great back nine is good enough if things go my way and they did somehow," he said.
The swing came under control, the rhythm came back and I started hitting iron shots close, almost so close you couldn't miss them - Adam Scott
"I have been working hard on my putting and couldn't ask for a better way to test myself, a six-footer to win a World Golf Championship event.
"I can't believe I have won back to back weeks and to win a WGC is huge. Somehow I need to bottle this up and keep it another four or five weeks through the Masters."
The win is Scott's tenth on The European Tour and second internationally in as many weeks after he claimed the Honda Classic on the US PGA Tour last week.
The 35 year old continues an excellent start to The 2016 Race to Dubai for Australians with Marc Leishman, Nathan Holman and Marcus Fraser having all claimed wins so far this season.
American Watson held a share of the lead at the turn with the help of a 60-foot eagle putt on the eighth and hit the front on his own at the 12th, but a closing 68 was not enough to hold off the Scott charge.
Willett turned in 33 to also be part of a four-way tie at the top before bogeying the 11th and, while birdies at the 12th and 16th reignited his challenge, that final wayward tee-shot saw him sign for a 69.
McIlroy had held a four-shot lead after three holes but bogeys on the seventh and ninth dropped the Northern Irishman into a share and he came home in level par 36.
Phil Mickelson, the other man to share the lead as the final group turned, finished at nine under after a 70, with fellow American Jimmy Walker a further shot back after a low round of the day 66.
The Spanish duo of Rafa Cabrera-Bello and Sergio Garcia finished at three under with Austria's Bernd Wiesberger and South African Louis Oosthuizen a further shot back.
