Memphis, TN - Dustin Johnson birdied two of his final three holes on Sunday to shoot a four-under 66 and come from behind to win the St. Jude Classic.
Johnson finished at nine-under 271 and won by a stroke at the TPC Southwind.
The victory was Johnson's sixth on the PGA Tour and first since The Barclays last year. Johnson missed two months earlier this season because of a back injury, but now, he will head to Olympic Club next week as a favorite for the U.S. Open.
John Merrick, one of three third-round co-leaders, carded a two-under 68 and finished second at minus-eight.
It was an incredibly tight finish on Sunday as several players were doomed by water at the closing hole.
After birdies at 16 and 17, Johnson had a one-shot lead, but four golfers were within one.
Rory McIlroy, who will defend his title at Olympic Club next week, trailed by one, but found water off the tee at 18 and made double-bogey.
Chad Campbell also got wet at the last, bogeyed the hole and finished two back.
Same thing happened to Nick O'Hern, the second of the trio in first after round three.
After all of the penalty drops, Campbell (68), O'Hern (69), Ryan Palmer (66) and U.S. Ryder Cup captain, and the final third-round leader, Davis Love III (69) tied for third at seven-under 273.
McIlroy built a two-shot lead with four birdies through his first 11 holes, but bogeys at 12 and 14 dropped him into a tie for first.
When Johnson made his birdies, and McIlroy his bogeys, McIlroy finished with a one-under 69 and shared seventh with Ken Duke (65), Seung-Yul Noh (66) and Robert Allenby (69). The group finished at minus-six.
