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.

"It was a great battle all day," said Woods.

Woods wasted very little time in trimming his three-stroke deficit entering the round. He knocked his second shot to 24 feet at the par-five second and rolled in the eagle effort. That got him within one of Harrington, but that changed quickly.

At the par-four fourth, Woods played his approach to 13 feet and converted the birdie putt. Harrington hit a spectacular shot from the rough to 20 feet, but wasn't able to make the birdie.

Four holes in and the two were already tied.

Even the tie didn't last very long.

Woods made a long birdie putt at the par-three fifth. That put him at 11-under par and gave him a one-shot cushion over Harrington, who kept plodding along with pars.

Five holes in and Woods was in the lead.

Both players parred the sixth, seventh and eighth holes and Woods appeared to be in trouble at nine. He drove into the right rough, but hit a sensational approach to seven feet. Woods drained that putt for birdie and it appeared to be a seventh title.

Nine holes in and Woods had a two-shot lead.

But Harrington showed the mettle that made him a two-time major champion last year. He rolled in an eight-foot birdie putt at the 11th and Woods did well to make par after a terrible drive in the left rough. Harrington cut the deficit to one and took some momentum.

Woods missed the green at the par-three 12th, but saved par. He once again missed the short grass from the fairway at 13 and his chip came up well short. Woods had 14 feet for par, but his putt died to the right and two were tied atop the leaderboard at minus-11.

Woods drove into the left bunker at 14 and his second went right of the greenside trap. He duffed his third into the trap, took almost no time at all and nearly holed his bunker shot. Woods settled for a bogey, while Harrington ran home a gutsy 15-footer for par to move one clear of Woods.

Then the 16th happened to Harrington and it was later revealed the duo was put on the clock for slow play.

For Woods, it was yet another spectacular win.

"We were locked horns pretty good," said Woods. "I made a couple mistakes there and Paddy was just being consistent. He did all the things he needed to do. Unfortunately, 16 happened."

Woods has won two weeks in a row after last week's title at the Buick Open. He has all the momentum heading into Hazeltine next week for the PGA Championship when he'll try to avoid going major-less for the first time since 2004.

"We'll start getting ready tomorrow," said Woods.

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.
