Woods, who earlier carded a third-round 72 with three bogeys in the last four holes, responded with five birdies in the final round to end on 16 under.

Britain's Luke Donald carded a fourth-round 73 and ended on 13 under with Tom Lehman and Charles Howell III.

European Ryder Cup skipper Bernhard Langer was tied fifth on 11 under while Vijay Singh was 24th on five under.

The 29-year-old Woods, seeking to regain the world number one ranking from Singh, only overtook joint-overnight leader Lehman on the penultimate hole after Lehman fired an approach shot into a bunker.

Woods sealed his victory with a birdie at the last to secure his first PGA Tour strokeplay title since the American Express Championship in October 2003.

Woods prevailed in the Target World Challenge, which he hosts, in December and won in Japan in November.

"It feels great," said Woods, who played 31 holes in total on Sunday after the third round was delayed because of fog.

"The start I got off to wasn't very good, but I hung in there.

"I just felt I needed to hang around. This course is so difficult, anything can happen but I kind of ground it out.

I don't get many chances to play in the final group with Tiger Woods and for 30 holes I held my own Tom Lehman

"It's hard to believe it's been that long to win on our tour, but it feels great."

But while Woods celebrated his slump coming to an end, Lehman was left to ponder his continuing drought.

The 2006 Ryder Cup captain has not secured a tour win in five years.

"I'm disappointed," Lehman said. "I really felt it was a great chance for me.

"I don't get many chances to play in the final group with Tiger Woods and for 30 holes I held my own. I had felt confident."

European Ryder Cup star Donald had headed the field with nine holes to play.

And he pledged to learn from his experience after blowing his advantage after a double-bogey six at the par-four 14th.

"I expected to play better - I had played spotless golf for three-and-a-half rounds," he reflected.
