And this on the picturesque and storied Pebble Beach Golf Links in Northern California where his grandfather once worked as a caddie and which he rates as one of his favourite places. Left Handed Ping G20 Irons

Mickelson, 41 and a four time major winner, is now also a four time winner of the AT&T Pebble Beach National Pro-Am after a classic final-round charge saw him shoot a magnificent, bogey-free, 8-under-par 64 and close with a 17-under total of 269 that left Woods, and, to a lesser extent South Korea's Charlie Wi, the overnight leader, spluttering in what little dust there was at verdant Pebble Beach Links.

The finest left-hand golfer of modern times was all smiles and graciousness as he raced clear to beat a stumbling Woods, who had been right up there in second place behind Wi and two shots ahead of Mickelson at the start of the day, by...wait for Left Handed Ping G20 Irons
...all of 11 shots.

For the second weekend in a row, Woods came into the final round looking for all the world like a winner, but after shooting an ugly 75 and missing putts from the 7th that were well within the compass of even the most humble of weekend warriors, he was left looking a sad and dejected figure, having posted five bogeys and just two birdies and having once more failed to win his first full-field event since the 2009 season.

Wi, who was six shots ahead of Mickelson when he teed off alongside him, closed with a level-par 72 to finish alone in second place, two shots behind Mickelson, whose six birdies and an eagle on the par-5 sixth hole also brought to 40 his total number of PGA Tour victories.

Fellow American Ricky Barnes finished third on 13 under and Aaron Baddeley on 12 under.

Kevin Na and Dustin Johnson tied for fifth on 11 under, with Ireland's on-the-up-again Padraig Harrington a shot further back on 10 under along with Ken Duke.
