Tiger Woods put himself in position to win his first PGA Tour event in nearly 2 1/2 years. Playing partner Phil Mickelson then showed him how to close the deal.

Mickelson stormed from six shots back by shooting a blistering 8-under-par 64 Sunday to win the AT&T Pebble Beach National Pro-Am at Pebble Beach, Calif.

Mickelson's spectacular bogey-free round allowed him to overtake third-round leader Charlie Wi and leave a stumbling Woods in his wake.

The popular lefthander finished at 17-under 269 to win the event by two strokes over Wi, who entered Sunday's round with a three-shot cushion.

It was the 40th PGA Tour victory for Mickelson, making him the ninth player in history to reach that milestone, and his fourth win in this event.

“It feels just amazing,” Mickelson said. “To be able to play the way I did the last 18 holes really means a lot.”

Woods, meanwhile, was unable to take advantage of Wi's early struggles. He had consecutive bogeys at Nos. 7-9 en route to a 3-over 75 that left him nine shots behind Mickelson.

“I didn’t hit it as bad as the score indicated, but I putted awful,” Woods said. “I made a ton of mistakes on the greens.”

Mickelson, the only player to shoot better than 67 on Sunday, needed just six holes to wrest the lead from Wi, who double-bogeyed the first hole and added bogeys at No. 5 and 6.

Three birdies in the first five holes gave Mickelson a share of the lead before taking control of the tournament with an eagle at No. 6 to move to 14-under.

Mickelson extended the lead with birdies at Nos. 13 and 14 before capping his magnificent round with a birdie at No. 18.

Wi, who has never won in seven years on tour, recovered from his disastrous start to birdie the final three holes for a 72 that left him alone in second place at 271.

Ricky Barnes closed with a 5-under 67 to nab sole possession of third place at 273. Aaron Baddeley matched Barnes' 67 and finished fourth at 274, one shot ahead of Dustin Johnson (70) and Kevin Na (70).

Woods, who hasn't won a tournament featuring a full field since the Australian Masters in November 2009, appeared poised for a long-awaited breakthrough after a sizzling 67 on Saturday left him four shots behind.

But he followed his birdie at No. 6 with the three straight bogeys that dropped him five shots behind a surging Mickelson.
