Tiger Woods capped a perfect Presidents Cup performance by providing the clinching point Sunday in America's 19.5-14.5 triumph over the International team.

Woods's 6 and 5 triumph over South Korean Yang Yong-Eun - the man who beat Woods for the PGA Championship title - gave the Americans an unbeatable lead in the biennial match play golf tournament.

It was the first time Woods had delivered the winning point in either Presidents Cup or Ryder Cup play, but he was too focused on taking down Yang to realize it right away.

"I didn't look at any boards," he said. "I saw we were down in six matches at one point, so I just kept my head down and tried to extend my own lead."

The United States brought a three-point lead into the final day and needed just five points from the 12 singles matches to win.

The Internationals needed eight points, and were never up in more than six matches simultaneously.

The Americans won for the sixth time in eight editions of the event, which pits a US team against an Internationals squad drawn from everywhere in the world except Europe.

The only Internationals victory was at Royal Melbourne in 1998 and the teams tied at Fancourt in South Africa in 2003.

It was fitting that Woods had the distinction of sealing the win.

He completed a perfect 5-0 week to join compatriot Mark O'Meara (1996) and Japan's Shigeki Maruyama (1998) as the only players to go five-of-five in the Presidents Cup.

British Open champion Stewart Cink got the ball rolling for the Americans with a 4 and 3 victory over Australian Adam Scott, a controversial wild card pick by Internationals captain Greg Norman.

Hunter Mahan beat Colombian Camilo Villegas 2 and 1, Anthony Kim defeated Australian Robert Allenby 5 and 3 and Sean O'Hair beat South African Ernie Els 6 and 4 before Woods polished off Yang.

Grudge match

Woods teamed for his first four victories with Steve Stricker. He was on his own against Yang, but downplayed the grudge-match aspect.

The South Korean became the first Asian man to win a major title with his victory in the PGA Championship in August, when he ended Woods's 14-for-14 streak in winning majors when leading after 54 holes.

"He got me there, and I figured I could get him here," said Woods, who had five birdies in 13 holes. "It certainly was not exactly the same atmosphere, but then it still was an important point."

Yang's only birdie of the day came at the first, when he took a 1-up lead over Woods. That didn't last long, as Yang struggled all day to find the fairway and lost two holes - three and six - with bogeys to go 2-down.

America's early push made for a distinct lack of drama at Harding Park Golf Course.

Villegas jumped to a 2-up lead over Mahan in the first match out, but the American was 1-up by the turn.

In what might have been a show of International determination, Villegas made Mahan hole a two-footer to halve 13 - but he proved unable to shake the American.

Phil Mickelson was pleased the Americans got the job done early - even if it made his 2 and 1 win over Retief Goosen moot.

"What was really cool was how our early matches went," said Mickelson, who was unbeaten this week with four wins and a halve.

"The guys in the first five, six spots, those were important spots for both teams," Mickelson said. "If the International side could have won those points, they could have got right back in the match, but our guys showed a lot of heart and class and ended up winning this event early."

American Justin Leonard had squared his match against Canadian Mike Weir by winning 18 and the two were poised for possible extra holes when Woods beat Yang and made it unnecessary.

"Nice of Tiger to make that putt so we didn't have to trek over to eight and keep going," said Leonard, referring to the Presidents Cup rule that single matches continue rather than end halved if the overall winner has yet to be determined.

South African Tim Clark shone in a losing cause with his 4 and 3 victory over Zach Johnson. Clark made eight birdies in his 15 holes.

Japanese teenager Ryo Ishikawa also notched a victory, the 18-year-old downing 49-year-old Kenny Perry 2 and 1.

Argentinian Masters champion Angel Cabrera and Aussie Geoff Ogilvy also notched victories, Cabrera beating Jim Furyk 4 and 3 and Ogilvy downing Stricker 2 and 1.

Fiji's Vijay Singh closed out the week by conceding a six-foot birdie putt to Lucas Glover at 18 to halve their match. The gesture gave US Open champion Glover his only half-point of the competition.

"Well, we had already lost on the 13th hole," Singh said. "So it was kind of almost demoralizing."
