Woods was never threatened after his second round

The world number one won by a massive eleven shots to underline his dominance of the Orlando course and send an ominous message to the golfing world ahead of April's Masters.

Woods took the lead at the end of his second round and extended it during the next 36 holes.

His final round of 68 took him to 19 under for the tournament, where he has averaged rounds of below 70 during the six times he has played there.

Woods accomplished all this on a day when he suffered from an upset stomach.

He threw up three times during the first five holes and often stopped in his tracks and doubled over, wincing in pain.

When he tapped in for par on the final hole, he had just enough strength left on a rainy afternoon to raise his right arm and salute the crowd.

"I wasn't feeling my best. That being said, I'm very happy with the way I played today," Woods said.

The 27-year-old American blamed his sickness on pasta he ate at home on Saturday night, saying he "started feeling pretty bad" about half an hour after the meal.

Tied for second place were fellow Americans Kirk Triplett, Brad Faxon, Kenny Perry and Stewart Cink.

Woods' much vaunted head-to-head clash with world number two Ernie Els was a massive disappointment, with the South African finishing 19 shots behind the winner.

The two had been paired together for the third round, and while Woods shot an accomplished 66, Els struggled to a 72.

While Woods' peers seem incapable of putting him under pressure, teenager Ty Tryon hinted there may be sterner challenges in years to come with a 69 to give him a tied 10th place finish.

Britain's Nick Faldo finished in the top 30, while Colin Montgomerie, in the middle of a terrible slump in form since he changed his clubs, came 31st.

The last player to win a PGA tournament for four successive years was the legendary Gene Sarazen, who accomplished the feat between 1926 and 1930.

The 11-stroke victory was the largest margin in the 25-year history of the Bay Hill event.
