The United States have claimed a one-point victory in the Presidents Cup after holding off a strong challenge from the International team to win 15.5-14.5.
Australians Adam Scott, Steven Bowditch and Marc Leishman won their singles matches on Sunday, having all struggled in the four-balls and foursomes in the preceding three days.
The fourth Australian, world No.2 Jason Day, had a disappointing event and lost his singles match 3 and 2 to British Open champion Zach Johnson.
New Zealand's Danny Lee lost his singles match to Dustin Johnson 2 and 1.
Leishman's surprise 1-up victory against world No.1 Jordan Spieth on Sunday looked like it might be pivotal.
But Sangmoon Bae was unable to hold off Bill Haas in the final match, with the American claiming a 2-up triumph after the Korean botched a chip shot on the final hole in front of his adoring home fans.
The US have now won nine of 11 Presidents Cup clashes.
