Woods’ round of 71 was one of just five sub-par scores shot on a day that could best be called — and frequently was — brutal. He three-putted the 18th hole after hitting a skybox off the tee and ended 36 holes tied with Vijay Singh and Carl Pettersson at 4 under.

Singh had the best round of the day, posting a 69 in the morning. The scoring average was just over 78 — the highest ever in a PGA Championship by more than two strokes.

The last time a single round stroke average was over 78 (78.727) on TOUR was on the final day of the 2004 U.S. Open. Dating to 1991, it also happened in round one of the 1999 British Open (78.314) and during round one of the 1993 Buick Invitational (78.383).

"It was tough out there — wow," Woods said. "You can’t take anything for granted, simple tap-in is not a simple tap-in. The putter is oscillating all over the place and the ball is oscillating and you know, you have to make an adjustment, at least I was on my down swing and my putts, because the putter is being blown all over the place.

"It’s a tough day. I mean, your start lines, Holy Cow, we are starting balls so far off line, to have it comeback in. There’s so much drift to this wind. It was just a tough day."

Pettersson had held the overnight lead. He led by as many as two on his final nine holes Friday but fell back with a string of three straight bogeys starting at No. 6 and ended up shooting 74.

"I thought 2 over today was probably like shooting 2 under yesterday," Pettersson said. "I played well. I hit some squirrely shots which is typical when it’s blowing 30 miles an hour, but I hit some really good ones, too. It’s just very difficult to get any rhythm in the round of hitting fairways and greens and my short game was good, which was nice on days like this."

The leaderboard has a decidedly international feel. There are two Aussies, two Swedes and two Americans, as well as an Englishman, a Welshman and a South African among the top 11 players on the leaderboard.

Ian Poulter is alone in fourth after making a bogey on the final hole on the way to a 71 that matched Woods for the low of the day. Jamie Donaldson and McIlroy, the 2010 U.S. Open champion, are tied at 2 under.

Play was suspended at 8:16 p.m. ET. Joost Luiten was the only player who didn’t finish his round. He’ll return to play the 18th hole at 7:30 a.m. and third-round tee times will run from 8:40 a.m.-3 p.m. off one tee.

The cut came at 6 over and included 73 players. Among those missing the weekend are recent U.S. Open champion Webb Simpson, who defends his title at the Wyndham Championship next week; world No.4 Lee Westwood, Ryder Cup captain Davis Love III and hopefuls for his team – Hunter Mahan, Rickie Fowler, Nick Watney, Matt Kuchar and Brandt Snedeker
