Sabbatini and Immelman were 2 up with three holes to play when Austin hit 6-iron into 6 feet on the 16th for a birdie, then holed a 15-foot birdie on the next hole to square the match. With the pressure on, Austin's 5-iron from 193 yards on the 18th just cleared a ridge and settled 5 feet from the hole.
After Sabbatini made his birdie putt from 8 feet, Austin closed out the match.
All but forgotten was another day of superb play from Austin, the 43-year-old former bank teller playing in his first team event. He delivered the key putts in a halve Thursday, and he was spectacular even soaking wet on a chilly afternoon, making eight birdies when his team needed them all.
It was the birdie he was trying to make that brought Austin so much attention.
The tees were moved up on the 14th hole so that it played 293 yards, and Austin pulled his drive just into the hazard. Sabbatini was on the green in one, Toms already was in the water, and Austin figured he had no choice but to try to get somewhere near the green for a shot at birdie.
"I knew deep down I probably couldn't pull the shot off,'' Austin said. "I was doing OK until I stepped on the rock. And once I stepped on the rock, I lost my balance.''
He was falling backward, then turned his body and went for the belly flop.
"I don't think I look any worse than I always do,'' Austin said.
He also has never been more proud of himself for the way he responded.
"I've never putted that good under those circumstances. But let's face it,'' he said. "I've never been in those circumstances before.''
In the first match of the day, Goosen chipped in for par and Angel Cabrera made a 10-foot birdie putt for a 1-up victory over Phil Mickelson and Hunter Mahan, the first match since 2003 in South Africa that the International team won on the 18th hole.
Canadian Mike Weir had another strong match a day after teaming with Singh against Austin and Mickelson, joining Ernie Els in a 3-and-1 victory over Zach Johnson and Charles Howell III. Geoff Ogilvy and Nick O'Hern also earned a point for the International team, beating Stewart Cink and Lucas Glover 1 up. In the lone U.S. victory, Stricker and Verplank beat Adam Scott and K.J. Choi 2 and 1.
