Vijay Singh keeps giving himself chances to end four years without a PGA Tour victory.
He made four birdies around the turn Friday for a 6-under 66 in the BMW Championship in Carmel, Ind., putting his name atop the leader board for the second time in his last four tournaments.
It won't get any easier the rest of the way.
Tiger Woods was a shot behind. So was Rory McIlroy. Going into a storm-filled weekend at Crooked Stick, four players who have reached No. 1 in the world were among the top six.
"I've got to keep it going," Singh said. "I've been playing well for two days for a while now, but I need four days of good playing."
Woods began slowly and finished strong, with birdies on his last two holes for a 67. McIlroy overcame four bogeys for a hard-earned 68. Joining them a shot out of the lead was Ryan Moore (66).
Lee Westwood (65) and Bo Van Pelt (69) were two shots off the lead.
Singh was at 13-under 131 on the Pete Dye course that is vulnerable to low scoring because of rain over the last several days.
These are supposed to be the FedEx Cup playoffs. The scores make it look like the old Bob Hope Classic, especially after a week in which McIlroy won on the TPC Boston at 20-under 264.
"You come to a Pete Dye golf course, and you don't expect to see 13 under par leading after two days," Woods said.
For the second straight day, Woods wasn't particularly sharp in any area of his game except
"I didn't have it with my swing," Woods said. "Just kind of fighting it around here. You look up at the scores, the guys are just running off. I just wanted to get to double digits (under par) today. I felt like that would have been a good accomplishment the way I was hitting the ball, and happy to get a couple of more."
McIlroy's mistakes all seemed to cost him, whether it was a three-putt bogey or bad lies when he missed the green. He was helped by a brilliant approach on the par-5 ninth to just inside 5 feet for eagle.
"I put myself in a great position going into the weekend," he said. "The round wasn't quite as good as it was yesterday. But I still managed to get around in 4 under par. I'm very pleased about that. I just need to try and find a little more consistency. It wasn't that bad out there, but just a couple of missed tee shots and a couple of missed iron shots."
McIlroy and Woods are both going for a tour-leading fourth win of the year.
Singh would settle for just one win at this point. His last victory was the Deutsche Bank Championship in 2008, the year he won the opening two FedEx Cup playoff events and essentially clinched the $10 million bonus.
LPGA Tour: Jiyai Shin shot a 3-under 68 to take a one-stroke lead at the Kingsmill Championship in Williamsburg, Va. The South Korean finish two rounds at 12-under 130 on Kingsmill's River Course. Danielle Kang was second after a 64. Pleasanton native Paula Creamer (67) and Dewi Claire Schreefel (66) were 10 under. Michelle Wie missed the cut with rounds of 75 and 71.
