PARAMUS, N.J. — Steve Stricker lost a ball and a big lead Saturday at sun-baked Ridgewood Country Club, leaving Kevin Streelman atop the leaderboard and more than two dozen players in The Barclays title chase.

After fading his drive into the rough on the par-4 12th, Stricker's approach shot from a tough angle skipped along the far side of the left rough and into a tangled mess of shoulder-high grass, bushes and weeds.

Despite TV replays and a large search party, the ball couldn't be located, and Stricker — four strokes ahead after 10 holes — took a penalty stroke and trudged back to the spot where he hit the costly shot.

The winner last year at Westchester Country Club, Stricker advanced the new ball 40 yards short of the green, hit his fifth shot 30 feet past the hole and two-putted for a triple-bogey 7 to drop to 7-under.

By the time Stricker signed for a 6-over 77, he was four strokes back at 4 under in a 12-way tie for 11th. On Friday, he shot a 7-under 64 in perfect morning conditions to take a three-stroke lead over Hunter Mahan in the FedEx Cup playoff opener.

Streelman, a 29-year-old Q-school graduate in his rookie season on the PGA Tour, took the lead at 8 under with a 25-foot birdie putt from the fringe on the par-4 16th and parred the final two holes for a 68 and an 8-under 205 total.

Vijay Singh, a three-time winner at Westchester, shot a 66 to join Sergio Garcia (69), Mike Weir (67) and Paul Casey (69) at 7-under. Garcia, a two-time champion at Westchester, had six birdies and four bogeys.

Kenny Perry, effectively the FedEx Cup leader with top-ranked Tiger Woods sidelined by a knee injury, was 5-under after a 72.

LPGA TOUR: At Portland, Ore., Helen Alfredsson shot a 67 to take a one-stroke lead after the second round of the Safeway Classic at Columbia Edgewater Country Club. Alfredsson matched her first round of 67 for a 10-under 134, one stroke ahead of Sophie Gustafson, who shot 68.

CHAMPIONS TOUR: At Snoqualmie, Wash., Scott Simpson matched the lowest round of the tournament with a 6-under 66 and holds a two-shot lead entering the final round of the Boeing Classic.

Simpson made five birdies on the back nine, running off a string of one-putts and surging away from a pack of chasers to put himself in position for his first victory in nearly two years. It's the first time on the Champions Tour that Simpson leads going into the final round.

U.S. AMATEUR: At Pinehurst, N.C., Danny Lee moved within one victory of supplanting Tiger Woods as the youngest champion in U.S. Amateur history. The 18-year-old Lee defeated Patrick Reed 3 and 2 in one semifinal, will play Florida State sophomore Drew Kittleson in today's 36-hole final.

By advancing to the finals, Lee and Kittleson earned exemptions into next year's U.S. Open and probable invitations to the Masters, as long as they remain amateurs.
