Tearful Watson holds off Mickelson

The American Bubba Watson held off late charges by Phil Mickelson and Venezuela's Jhonattan Vegas to clinch his second PGA Tour title with an emotional one-shot victory at the Farmers Insurance Open late on Sunday.

Left-hander Watson coolly birdied the par-five last as he closed with a sparkling five-under-par 67 at Torrey Pines. The long-hitting 32-year-old got up and down from a greenside bunker at the 18th, sinking a curling 12-footer before celebrating.

The three-times champion Mickelson had a chance to force a play-off by holing a wedge shot from 72 yards but his ball ended up four feet from the pin.

"It means a lot," said a tearful Watson, whose father Gerry died late last year after a lengthy battle with lung cancer.
