For Sean O'Hair, the race is on to qualify for the Masters.

By his best calculations, to qualify for the elite field at Augusta National in six weeks, O'Hair needs to win a tournament at one of the next three weeks of the PGA Tour's Florida Swing.

Having slipped to 82d in the world golf rankings, only top-five finishes or a victory at the upcoming Honda Classic, Tampa Bay Championship or the Arnold Palmer Invitational (formerly Bay Hill) would be enough to catapult O'Hair into the top 50 in the rankings, earning him a ticket to Augusta. (Paul Goydos jumped from 133d to 39th when he won the Sony Open).

"I need to win," O'Hair, 24, said Friday from his home in West Chester, where he was recovering from a mild bout of food poisoning (bad pizza).

O'Hair, rookie of the year and winner of the John Deere Classic in 2005, is more upbeat about his chances than you might expect after he made only one cut (Nissan Open) in four tournaments during the just-ended West Coast Swing.

"I think the prettiest place in the world is Monterey. But golf-wise I am never comfortable in California," said O'Hair. "I never played well there in juniors, the mini-tours or on the PGA Tour. I think it has something to do with the grass."

For golfers who grow up on the East Coast grasses (Bermuda and bent), the poa annua grass so common on greens on the West Coast can be maddeningly tricky.

"They make you think you're a bad putter when you're not," said Steve Lucas, O'Hair's caddie and father-in-law.

Still, it's enough to get inside your head, which is why O'Hair plans to spend time at the Honda with Bob Rotella, sports shrink to the Tour stars.

"It's definitely mental," O'Hair said of his putting woes. "Rotella thinks I've got to forget about making the putt or missing the putt and just get over the ball and react to the target."

What's so frustrating, said O'Hair, is that the rest of his game has never been better, even with the post-winter rust on his swing. "I haven't hit the ball as well or as consistently in my career," he said. "It's just on the greens."
