Tiger Woods admitted that he was flattered by the four-shot winning margin at the Bay Hill Invitational tournament in Orlando.

The world number one carded a final-round three-under-par 69 to finish four clear of New Zealander Michael Campbell.

Woods finished on 13 under par with a total of 275 to become the first player in USPGA history to win three separate PGA Tour tournaments three years in a row.

Phil Mickelson was a stroke clear with nine holes to play but the left-hander dropped a series of shots to gift the title to Woods.

Mickelson, Rocco Mediate, John Huston and Len Mattiace finished tied for third place on 280.

Woods said: "It was quite a fight out there. I tried to just hang in there and just gave myself a lot of looks at birdies, and tried not to make my bogeys on the back nine.

"You don't want, with the conditions being this difficult, to have to go on that back nine and feel like you have to make a bunch of birdies, because it's just too hard.

"The greens are too firm, and the pins are not that easy to get to."

World number two Mickelson was upbeat despite his collapse. He said: "I played well but I made a bunch of bogeys that really took me out of the position I wanted to be in."

Campbell was happy with his performance - the New Zealander's highest-ever finish on the US Tour - but conceded that Woods was just too good on the day.

"I was playing well. But once again, you know, he just topped it off once again to win three times in a row," said Campbell.
