San Francisco, CA (My Sportsbook) - Tiger Woods hit two spectacular shots on his last two holes to lead Steve Stricker to victory and the United States to a three-point lead after three sessions of the Presidents Cup.

The U.S. is ahead 10-7 after Saturday morning's five foursomes matches and Woods anchored a late rally for the Americans.

He and Stricker were 2-down to Mike Weir and Tim Clark with six holes to play, but a birdie at 13 cut the deficit to 1-down.

After three straight halves, Woods drove into a greenside bunker at the short par-four 17th. Weir laid up off the tee, then Clark wedged his approach to five feet.

Stricker hit the lip with his bunker shot and left Woods with 22 feet. Knowing that if Woods missed and Weir made his putt, the match would be over, Woods stepped up and poured in the birdie putt on its last rotation. Weir pushed his short effort and the match was all-square with the par-five 18th at Harding Park to go.

Stricker found the short grass off the tee and Clark did as well. Weir pulled his second into the rough right of the putting surface.

Woods hit a perfect four-iron he knew was perfect. Immediately after impact, Woods twirled his club and gestured with his hands that the shot would be close.

It was.

Woods' ball bounced inside 10 feet from the stick eliciting a roar from the gallery.

Clark hammered his chip 25 feet past the stick and Weir missed the birdie putt, then took off his hat to concede the hole and the match to Stricker and Woods.

"It was fun to watch," joked Stricker. "I had a front-row seat."

For Woods, it was a brilliant performance at the most opportune time, starting at 17.

"I had no choice," said Woods. "We miss, they make, it's over. It just crawled in."

The Americans started great with wins from Phil Mickelson and Sean O'Hair over Camilo Villegas and Retief Goosen, 5 & 3, then Justin Leonard and Jim Furyk beat Ernie Els and Adam Scott, 4 & 2. After that victory, the Internationals appeared to be in control.

They were ahead in all three remaining matches, but only managed 1 1/2 points from them.

British Open champion Stewart Cink and Hunter Mahan birdied the last to pull out a halve against Vijay Singh and Robert Allenby. Then Woods turned the momentum of things with his comeback win.

In the anchor match, Ryo Ishikawa and Y.E. Yang handled Kenny Perry and Zach Johnson, 3 & 2.

While Woods played the role of hero, playing just as well this week has been Mickelson.

He and O'Hair lost the third hole, but won four and five. By the time the match made the turn, the U.S. was 2-up thanks to a chip-in birdie from O'Hair.

The Americans won 11, halved 12 after a long putt from O'Hair and moved 4-up when Mickelson sank a 15-footer to win 13. The match was over on the 15th green and O'Hair finally got a win, while Mickelson has yet to lose this week.

"I feel so much better on the greens," said Mickelson. "We're excited to have gotten this point. We're excited to be the first group out and lead."

Leonard and Furyk were all-square with Els and Scott at the turn, but a birdie at 10 gave the U.S. a 1-up cushion. They got to 2-up at 13 and wins at 15 and 16 closed out the match.

In the third match Saturday, Cink and Mahan jumped out early, but the Internationals claimed the lead before the turn. Singh and Allenby were 2-up with four to play, but lost 15 to par.

At the 18th, Singh hit a poor drive that didn't allow Allenby to go at it in two. Mahan got on in two and Singh hit his team's third to 12 feet. Cink ran his eagle putt to win the hole and halve the match two feet past, then Allenby missed his birdie putt.

Mahan kicked in the short birdie putt to steal the halve.

Ishikawa and Yang, who have become Norman's most dependable team with a win on Friday, were 1-up through five and never looked back. Their lead got as big as 3-up and when Ishikawa rolled in a short birdie putt at 16, the 18-year-old and PGA Champion earned a second victory.

There are five four-ball matches Saturday afternoon, then 12 singles matches on Sunday.
