Woods, without a victory on the PGA Tour since autumn 2009, fell to Nick Watney in the second round 1-up. Woods had a chance to send the match to extra holes, but missed a 6-foot birdie putt on the 18th green of the Ritz Carlton Golf Club course. He will continue his attempt to regain his old form when he takes part in the Honda Classic next week.
