Adam Scott's hot streak has continued, with a one-shot win in the World Golf Championships in Miami, a week after winning the Honda Classic.

Scott fell six shots behind after two double bogeys in his opening five holes of the final round, before staging a stunning comeback to beat second placed Bubba Watson by one shot.

Scott shot six birdies in nine holes to record a final round three-under-69, to finish 12-under for the tournament.

The 35-year-old moves up three places from No.9 to No.6 in the world and is in great form heading into next month's US Masters.

"I've used my experience to my advantage the last couple of weeks," said Scott.

"I've realised these are tough courses. Although you never want quads and doubles you're never out of it. It was such a challenge out there today.

"I really can't believe I've won back-to-back weeks, but to win a world golf championship is huge again and I've just got to keep pushing hard for the next couple of weeks."
