Tiger Woods clinched The Presidents Cup for the US team with the winning point over the Internationals in the singles of the teams match play event at Royal Melbourne on Sunday.
The former world number one thrashed Australian Aaron Baddeley four and three to push the defending champion Americans beyond the 17.5 points needed to claim their seventh Presidents Cup against the non-European Internationals.
Woods also provided the clinching point when the Americans posted a 19.5-14.5 triumph over the International team at the previous event in San Francisco in 2009.
The Americans split Sunday's 12 singles with the Internationals 6-6, finishing overall 19-15 winners.
The powerful American team went into the final day's singles leading by four points and although Greg Norman's International team made a charge to get within two points they were too strong in the final matches.
It was a dominant performance by the Americans, who won both the foursomes, split one of the four-balls and narrowly lost the other fourball.
Apart from Woods, America's other singles winners were Hunter Mahan, Nick Watney, Jim Furyk, David Toms and Steve Stricker.
The Internationals faced a tall order heading into the final day as no team trailing into the singles matches had gone on to win The Presidents Cup, although in 2003 the United States trailed 12.5 to 9.5 and fought back to tie the competition in South Africa.
South Korean Kim Kyung-Tae, who holed a pressure putt at the last hole to beat Woods and Dustin Johnson in Saturday's four-ball, carried on his form with a resilient one-up win over Webb Simpson in the day's opening singles.
Victories followed from teammates Charl Schwartzel of South Africa, Japan's Ryo Ishikawa and Australian Greg Ogilvy as the Internationals began strongly.
But Mahan and Watney restored control with comfortable victories before Furyk, Toms and Woods got the Americans across the finish line with Stricker winning the day's final singles match two and one over South Korea's Y.E. Yang.
Adam Scott had a two and one win over Phil Mickelson and Retief Goosen edged out Matt Kuchar one-up for the Internationals' other wins.
It was an accomplished performance from the Americans who came to grief when they last played The Presidents Cup at the tough Royal Melbourne layout, losing 20.5 to 11.5.
The classic sandbelt course tested all the golfers to the limit in Friday's hot blustery conditions and played a little easier on the weekend in cooler weather.
