AKRON, Ohio — Vijay Singh nearly threw away the Bridgestone Invitational by missing three putts inside 8 feet on the back nine at Firestone. He won his first World Golf Championship by making the last one, which was all that mattered.

Singh ended an 0-for-34 drought on the PGA Tour by swirling in a 3½-foot par putt on the final hole today to close with a 2-under 68 for a one-shot victory over Lee Westwood and Stuart Appleby.

As shaky as Singh looked down the stretch, Phil Mickelson was even worse.

Mickelson played bogey-free through the first 14 holes to build a one-shot lead, then threw it away by making three bogeys from the bunker on the final four holes to finish with a 70, two shots behind.

According to tour statistics, Singh was 8-of-18 on putts from 4 to 8 feet during the tournament, and the last thing he wanted was to face another attempt. But he left his 30-foot birdie putt well short of the hole, and was relieved to see gravity pull it into the hole.

"I didn't want to have a 4-footer," he said. "I was kind of sweating it. But I'm glad it went in."

Singh had not won on U.S. soil since the Arnold Palmer Invitational in March 2007, and twice this year he blew 54-hole leads at Pebble Beach and Bay Hill. But he finally got it done, winning for the 32nd time on the PGA Tour.

After falling out of the top 10, the victory is expected to move him up to No. 4 in the world.

Singh finished at 10-under 270 and earned $1.35 million for his first WGC title.

Westwood, who could have moved up to No. 4 in the world with his first U.S. title in 10 years, rallied from a five-shot deficit with 11 holes to play to get within one of the lead. But he missed a 7-foot birdie on the 17th, and his 15-foot birdie putt from the fringe on the 18th to tie for the lead was left all the way.

An equally impressive rally belonged to Appleby, the only player to compete in all 29 of these WGC events since they began in 1999. He was seemingly out of the picture until a 30-foot birdie on the 16th, a 3-foot birdie on the 17th and an 18-foot birdie attempt on the final hole that just stayed right of the cup.

"I had a putt for what I thought would get me into a playoff," Appleby said. "I hit the best putt I could have hit without it going in."
