PEBBLE BEACH, Calif. — Vaughn Taylor is headed home to the Masters with his first PGA Tour victory in more than a decade, and he can’t believe it.

Neither can Phil Mickelson.

Taylor, who hasn’t had a full PGA Tour card for the last the three years, ran off four straight birdies on the back nine to close with a 7-under 65 and won the AT&T Pebble Beach Pro-Am on Sunday when Mickelson missed a 5-foot putt on the final hole.

“It’s been a long time. I didn’t think it was going to happen,” Taylor said. “I worked so hard. I kept getting knocked down, knocked down. I’m just at a loss for words.”

A week of spectacular weather on the Monterey Peninsula ended with a stunning conclusion for both players.

Taylor is No. 447 in the world and won his first PGA Tour event against the top players. His previous two victories were the Reno-Tahoe Open (2004 and 2005), which is held opposite a World Golf Championship. He just returned from South America and a pair of Web.com Tour events.

And then there was Mickelson, going for his 43rd career PGA Tour victory and his record-tying fifth at Pebble Beach, staked to a two-shot lead with no one near his pedigree within five shots of the lead.

Mickelson, however, struggled from the start and could not keep making enough par putts to hold off Taylor.
