Tiger Woods eyes world number one spot at Arnold Palmer event
Tiger Woods will not be satisfied if he returns to the world number one spot with a victory at this week's Arnold Palmer Invitational in Florida.
The American, 37, who is the defending champion and has won the event seven times, will replace Northern Ireland's Rory McIlroy who is not playing.
The 14-time major winner, who has spent a record 623 weeks as world number one, was last top in October 2010.
"I don't want to be as good as I once was, I want to become better," he said.
And he goes into this week's Bay Hill tournament - which starts on Thursday - as favourite to win a third event of 2013 as he continues his build-up to the first major of the season, the Masters at Augusta in April.
"Just got to win this week, not too complicated," said Woods.
"Things are still becoming more efficient. You know, these two wins I've had this year have been built [on] some nice leads, which means I've played really well and things are starting to come around and become more efficient day in and day out."
Golf legend Palmer, who won seven majors between 1958 and 1970, believes Woods is back to his best.
The 83-year-old American told the Golf Channel: "He looks probably as strong and as good from a golf perspective as I've ever seen him.
"I think his swing and his posture and his attitude is far better than it's been in some time, and it takes me back to when I first played with him at Augusta when he was a rookie."
Woods begins his opening round alongside South Africa's Open champion Ernie Els and England's Justin Rose, with the trio teeing off on the 10th at 12:05 GMT on Thursday.
Northern Ireland's Graeme McDowell, runner up to Woods at Bay Hill in 2012, also tees off on the 10th, with England's Ian Poulter and American Keegan Bradley, in the group behind Woods.
