Vijay Singh posted an impressive, 3-under 69 on Friday to take the clubhouse lead during the windy second round of the PGA Championship.

Singh, a two-time PGA Champion, finished two rounds at 4-under 140 at a much tougher Ocean Course at Kiawah Island.

Singh, 49, is two behind Gary Woodland, who birdied his second hole Friday.

First-round leader Carl Pettersson bogeyed his first hole, the 10th, and fell into a tie for second with defending champion Keegan Bradley, Rory McIlroy and Pat Perez. That group is all at 5-under par and in the middle of round two.

Tiger Woods holed a 12-foot par save on his first hole Friday and is 3-under par.

Jamie Donaldson is next in line in the clubhouse after a 1-over 73 left him at minus-2.

Adam Scott, who is playing his first major since he bogeyed the final four holes on Sunday to lose The Open Championship to Ernie Els, shot a respectable 3-over 75 and is tied with Aaron Baddeley, who also had a 75 Friday, at 1- under par.

"It's really very tough," said Scott. "So I think, consider 75 kind of a par round of golf out there today."

Phil Mickelson braved the wind on Friday with a 1-under 71. He is through 36 holes at even-par 144.

Friday brought quite a compelling change from Thursday's benign conditions.

One day after 44 players broke par, only Singh, Mickelson and reigning U.S. Open champion Webb Simpson shot par or better with most of the morning wave done for the day.

Thunderstorms were forecasted for Friday afternoon, but only one decent-sized storm passed through. Play never stopped and skies are blue.

Even Singh wasn't immune from the windy conditions.

"If you had a golf course like this and you asked me to go and play golf in windy conditions, I'd say no, I'm not going to play," said Singh, who won this title in 1998 and 2004. "But it is a major, and we have to go out there and just struggle and manage yourself the best you can, I guess.

Singh mixed five birdies and two bogeys in his round Friday and his 69 was definitely fine with him.

"I'm happy I shot 69 for sure," said Singh. "I would have taken 72 when I started off. And I'm happy I'm done, too."
