Akron, OH (My Sportsbook) - Tiger Woods did it again.

The world's best fired a final-round, five-under 65 on Sunday to come from behind and win his seventh WGC-Bridgestone Invitational title. He finished at 12-under 268 and won by four at Firestone.

The victory was significant for several reasons.

Woods became the first player in PGA Tour history to win seven times on the same course. He is one away from joining Sam Snead as the only golfers to ever win the same championship eight times.

This was Woods' 70th PGA Tour victory and he is only three behind Jack Nicklaus for second place all time.

"I'm happy with seven here and 70 total," said Woods, who collected his fifth win of the year.

Overnight-leader Padraig Harrington got tripped up by one hole. He struggled to a two-over 72 and fell into a second place tie with Robert Allenby, who posted a 66, at minus-eight.

The pivotal hole became the par-five 16th.

Harrington was one shot ahead of Woods and both hit tee shots that required lay ups. Woods hit his second into the fairway and Harrington played a bad second that was on a hill near a bunker.

Woods hit an eight-iron from 182 yards out right at the flag. The ball spun back inches from going in and the pressure was firmly on Harrington for his third.

From an awkward stance, Harrington's shot sailed into the right rough. As soon as he hit his pitch, one could hear Harrington groan. He hammered his pitch and the ball went directly into the pond.

Harrington took a long, lonely walk back to the other side of the water and hit his sixth shot to the back fringe. He chipped to three feet and holed out for the triple-bogey.

Now three ahead, Woods parred 17 and hit a great approach to five feet at the last. He converted that one for a final birdie, a great punctuation to a historic victory.

Masters champion Angel Cabrera (67) and Hunter Mahan (66) shared fourth at minus-seven.

British Open champion Stewart Cink (68), Steve Stricker (67) and Miguel Angel Jimenez (68) tied for sixth place at six-under 274.

Phil Mickelson, who returned for the first time since a runner-up at the U.S. Open, shot a three-over 73 on Sunday and shared 58th place at seven-over-par 287.
