Watney holds nerve to win Buick

Nick Watney birdied the last hole to win the Buick Invitational by one shot at Torrey Pines.

Watney was level with John Rollins as they played the par-five 18th hole and sealed his second PGA Tour victory with a birdie putt from just inside three feet.

Watney set up the birdie with a beautifully judged putt from 63 feet as he finished 11 under par following a four-under 68.

Rollins then missed a 12-footer for birdie and tapped in for a par to finish 10-under. He had started the day with a three-stroke lead, an advantage he still held at the turn, but was eventually overhauled by Watney after posting a two-over-par 74.

Camilo Villegas finished tied for third at nine-under along with Lucas Glover, who closed with a 68.

Ireland's Padraig Harrington shot his best round of the tournament, with a 68, but that was only good enough to see him finish on one-under, ten shots off the winner.
