Atlanta, GA (My Sportsbook) - Sergio Garcia fired a three-under 67 on Saturday to move atop the leaderboard after the third round of the Tour Championship.

Garcia finished 54 holes at East Lake Golf Club at eight-under 202 and is three ahead of overnight leader Anthony Kim (72) and Phil Mickelson (69).

Garcia was paired with Kim in the final group Saturday in a rematch of the opening singles match last week at the Ryder Cup. On that day, Kim destroyed Garcia, 5 & 4, but on Saturday, Garcia gained some modicum of revenge.

"Obviously, A.K. (Kim) wasn't on his 'A' game," said Garcia.

Camilo Villegas shot a one-under 69 and is alone in fourth place. Ben Curtis (68) and Robert Allenby (67) are knotted in fifth place at two-under 208.

This is the final event of the FedEx Cup Playoffs and is merely a formality to the coronation of Vijay Singh as the winner. As long as Singh can complete his final round on Sunday, he walks off as the FedEx Cup winner and is $10 million wealthier.

"I tried to play as normal as possible," said Singh, who shot a two-over 72 on Saturday and is tied for 24th at plus-nine. "On almost every tee shot, somebody's congratulating you. It's kind of weird."

The winner of this championship will come in second for the FedEx Cup and earn an additional $3 million.

That man is now Garcia.

He trailed Kim by two shots at the start of the round and Kim extended his lead thanks to a 22-foot birdie putt at the third. Kim hit his tee ball into water at the sixth and drained a nine-footer just to save bogey.

It was after that that Garcia made his move.

At the seventh, Garcia ran home a seven-foot birdie putt to cut the deficit to a stroke. The ninth became a critical swing hole and it started very poorly for Kim and even worse for a member of the gallery.

Kim's drive hit a spectator in the face and the ball bounced several feet away after impact. Kim stayed with the man, whose face was bloodied, until he was taken for treatment.

"It's a very difficult situation," admitted Kim. "I felt terrible. You never want to see that anywhere, let alone when you're the guy who hit the golf shot. I think he's going to be all right."

Garcia kicked in a short birdie putt at the hole to join Kim in the lead. He missed the green short at the par-four 13th and could not get up and down for par.

Kim dropped a shot at the 14th when he missed a short one for par. Mickelson joined the lead after a tap-in birdie at the par-five 15th, but Garcia took over down the stretch.

Garcia rolled in a three-foot birdie putt to take the lead at 15. Mickelson missed the fairway and green en route to a bogey at 16, then Kim hit a tent with his approach at the same hole. That led to a bogey and Garcia was two clear of his Ryder Cup opponents.

Garcia's approach at the 17th rolled to the back fringe. It didn't matter. The Spaniard converted his 17-footer for birdie to take a three-shot lead. The three main principals parred the last and now Garcia looks for his eighth win on the PGA Tour.

"I managed to make a couple of birdies here and there," said Garcia, who won this year's Players Championship. "I played pretty solid overall."

Garcia has held at least a piece of the 54-hole lead only five times on the PGA Tour. The last was the 2007 British Open, which he lost to Padraig Harrington, and Garcia has only won two of those five times. The last time Garcia won with the third-round lead was the 2004 Byron Nelson.

Kim was not sharp on Saturday. He hit only four fairways and had a pretty decent explanation for his poor play.

"I was out of my rhythm," said Kim. "I didn't do the things I usually do before I tee off. I thought my tee time was 11:55 and it was 11:25. No excuses. I should've found my swing."

Mickelson was efficient in round three with three birdies and two bogeys.

"This is my last tournament of the year in the U.S.," said Mickelson. "I'm trying to give it everything I can to finish the year right. If I were able to come out on top tomorrow, I think it would change the way I look at the year."

K.J. Choi shot an even-par 70 and is alone in seventh at minus-one. Mike Weir posted a one-over 71 and is eighth at even-par 210.

Kevin Sutherland (69), Jim Furyk (69) and Ernie Els (70) are tied for ninth at one-over 211.
