Gainesville, Va. ? Chris DiMarco came up aces, Tiger Woods and Jim Furyk came through with clutch comebacks, and Retief Goosen and Adam Scott proved as formidable as ever Saturday, all of them turning in solid performances that left the Presidents Cup tied going into a final round of 12 singles matches.

Each team had 11 points, the first time the Presidents Cup has been tied going into Sunday since it began in 1994.

“I think tomorrow is a toss-up,” Phil Mickelson said. “The International team is very strong, 12 of the best players in the game. They are extremely tough and are playing some extremely good golf. I feel the American team is playing exceptional golf, as well. I have faith in my team. But we have a lot of work ahead of us.”

Woods will face Goosen in the third match, while Fred Couples will take on Vijay Singh in the fifth match. Mickelson and DiMarco anchor the U.S. team, facing Angel Cabrera and Stuart Appleby in the final two matches.

The star was DiMarco, who has only three PGA Tour victories in his 10-year career but plays like a major champion in these team events. He made only the second hole-in-one in the Presidents Cup in the morning, holed just about every putt that mattered and joined Mickelson in two victories the Americans needed.

DiMarco and Mickelson were so dominant that neither of their matches Saturday reached the 16th hole.

The Americans had a chance to take the outright lead in the final better-ball match of the afternoon. Couples, who has provided some of the most dramatic images from Robert Trent Jones Golf Club, hit a wedge into eight feet on the 18th hole and was poised to score a 1-up victory. But his putt stayed above the cup as he and Davis Love III had to settle for a halve with Michael Campbell and Cabrera.

No one had to work harder than Woods and Furyk, who birdied the last two holes in alternate shot Saturday morning to earn a halve against Singh and Appleby, then went the distance against them in the afternoon in a better-ball 2-up victory.
