Dustin Johnson closed with a 3-under 69 on Sunday as he came from behind to win the WGC-Cadillac Championship by one stroke.

Johnson finished at 9-under-par 279. This was his eighth PGA Tour win and second title on the European Tour, both of which were World Golf Championship victories.

The win came in Johnson's fifth start after returning from a 6-month leave of absence from the PGA Tour. He had missed the cut in two of his previous four starts, finished fourth at Pebble Beach and lost in a playoff at the Northern Trust Open.

J.B. Holmes, who led after each of the first three rounds, had three early bogeys before he played the final 12 holes in even-par to close with a 3-over 75. Holmes ended alone in second place at minus-8.

Bubba Watson birdied four of the first seven holes in the final round to grab a 2-shot lead, but three bogeys on the back nine at Trump National Doral left him two back at 7-under-par 281. Watson shot 1-under 71 in the final round.

Adam Scott (71) and Henrik Stenson (72) shared fourth at minus-4. Louis Oosthuizen stumbled to a 1-over 73 and ended alone in sixth place at 3-under 285.

World No. 1 Rory McIlroy found water twice at the 18th before chipping in for double-bogey. He managed an even-par 72 and shared ninth place at 1-under 287 with Kevin Na (71) and Ryan Moore (76).
