Geoff Ogilvy has ended a drought of nearly two years earning a hard-fought one-stroke victory at the $US8 million ($A8.78 million) CA Championship.

Australian Ogilvy, who had nine holes left when play resumed at Doral Resort's Blue Monster on Monday, was not at his best, but pars at every hole on the back nine proved enough to claim the fourth professional victory of his career.

Helped by an unlikely chip-in par at the 13th hole, he carded 71 to finish at 17-under-par 271, his first victory since the 2006 US Open.

Fiji's Vijay Singh, South African Retief Goosen and American Jim Furyk tied for second on 16-under, while Tiger Woods' six-month winning streak ended when he finished fifth, two strokes behind.

Ogilvy is just the third player to win more than one World Golf Championships event, joining Tiger Woods (15) and Darren Clarke (two).

The 30-year-old from Melbourne was not in danger of dropping a shot over the final nine holes, apart from the 13th, but he could not find the birdie he so badly wanted to put some distance between himself and the field.

He came to the dangerous par-four 18th leading by the barest of margins, and showed plenty of poise under pressure, smoking a drive down the middle of the fairway, from where he found the heart of the green with his approach shot.

After Ogilvy stroked his first putt stone dead, Singh had a chance to force a play-off with a chip-in birdie, but it did not fall, leaving a relieved Ogilvy to tap-in for victory.

Woods, whose six official tournament winning streak ended, had a miserable week on the greens, but still finished only two shots back, demonstrating without question that he very much remains the man to beat at next month's Masters.

"I made too many mistakes," he said.

"I had four three-putts this week, two bad lies in bunkers and a photographer on (hole) nine yesterday. All in all, to finish only two back, that's a good sign.

"People don't really understand you need to have something happen in order to win tournaments."
