Teary Bubba devotes Torrey title to parents

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 win at the Farmers Insurance Open in San Diego.

Left-hander Watson coolly birdied the par-five last to keep his challengers at bay as he closed with a sparkling five-under-par 67 on the tricky South Course at Torrey Pines.

The long-hitting 32-year-old, a stroke off the pace going into the final round, got up and down from a greenside bunker at the 18th, by sinking a curling 12-footer before pumping his right fist in celebration.

Three-time champion Mickelson had a chance to force a playoff by holing a wedge shot from 72 yards out but his ball ended up four feet from the pin to set up a closing birdie.

"It means a lot," said a tearful Watson, whose father Gerry died last year after a lengthy battle with lung cancer. "My dad is not here. Mum, I love you."

Asked if his breakthrough win at last year's Travelers Championship had helped him at Torrey Pines, Watson replied: "No. It's hard every time."
