Paramus, NJ -- (Sports Network) - Kevin Streelman carded a three-under 68 Saturday to take a one-stroke lead after 54 holes of The Barclays, the first FedEx Cup Playoff event.

Streelman completed three rounds at eight-under-par 205.

Vijay Singh (66), Mike Weir (67), Paul Casey (69) and Sergio Garcia (69) share second place at minus-seven.

The story of the day though was second-round leader Steve Stricker's collapse. He birdied the first and third to move to 12-under and after he parred the fourth, his lead was four.

Stricker bogeyed the seventh, then played the back nine in seven-over 43 to tumble into a share of 11th at four-under-par 209 at Ridgewood Country Club.

Stricker stood at 12-under after his opening birdies. He missed the green at the seventh and that led to his first bogey. At the par-four 11th, Stricker again missed the green leading to his second bogey.

Now at minus-10 and still owning a three-stroke lead, things really fell apart for Stricker. His tee ball on the 12th landed in the right rough. He pulled his second shot well left of the green and into a native area.

After an extensive search, he declared a lost ball and marched back to where he hit the second shot from. Stricker played his fourth down the fairway, then pitched on and two-putted for a triple-bogey.

That created a six-way tie for the lead as Garcia bogeyed the 14th to also drop to minus-seven.

Streelman was part of that six-way tie. He opened his round with a birdie on the first, then he parred the next six holes.

The 29-year-old dropped in back-to-back birdies from the eighth to move to eight-under.

Streelman gave one of those shots back as he tripped to a bogey on the par- three 10th. He parred five in a row as the leaders came back to him.

"I was just kind of hanging around, playing solid golf and all of a sudden I saw the leaders at 12-under, then back to 10-under and all of a sudden to fall back to seven-under, I knew they must have had a little hiccup there," said Streelman, who could become the third player to win this title in their first appearance at the event. "I was fortunate. It's still early though, there's plenty of golf left."

He rolled in a birdie putt on the par-four 16th to move into first at minus-eight. Streelman parred the final two holes to maintain his one-shot lead.

"It's a great thing. To be able to share some of this with friends and family, it's a dream come true for me, for 15 or 20 years now," said Streelman, who has several friends and family members at the event with him. "To be here and be in contention in a major tournament like this, it's pretty cool."

Stricker's collapse continued as he bogeyed three of four holes from the 14th to tumble to minus-four. He got up and down for par at the last to finish there.

"Through 10 holes I was one-under and doing okay, then made two stupid plays in a row at 11 and 12," admitted Stricker. "Really the one at 12, was one of the dumbest plays I've ever made, trying to do what I did out of the rough and I paid for it. And from that point on, it was a struggle to get it in."

Garcia was hot early with three birdies in the first five holes. After tripping to bogeys at seven and eight, he birdied nine and 10 to move to minus-eight, where he trailed by three.

The Spaniard tripped to another bogey on the 12th, but recovered with a 13- foot birdie putt at the 13th. Garcia could not save par from a bunker at the 14th to dip back to minus-seven. He parred out to share second.

"It was a little bit of a mixed bag today," Garcia said. "Obviously a couple of tee shots here and there that I would like to have hit a little better. Overall, you've got to realize the course was playing tough and the wind was coming up and down, so it was tough to pull some of the clubs."

Singh, a three-time winner of this event, carded three birdies and a bogey on the front nine to move to minus-four. He ran off three straight birdies from the 14th to climb to minus-seven. Singh parred the last two holes.

Weir birdied three of the first four holes to get to minus-six. He bogeyed the 10th, but gained a share of second thanks to birdies at 14 and 15.

Casey notched five birdies and three bogeys in his round of 69.

Robert Allenby and Jason Day both fired five-under 66's to move into a share of sixth place at five-under-par 208. They stand alongside Kenny Perry (72), Kevin Sutherland (69) and Angel Cabrera (72).

Stricker, the defending champion, shares 11th with 11 other players, including his third-round playing partner Hunter Mahan, who shot 74 on Saturday.
