The wind played havoc at Kiawah Island on Friday, but that didn't  stop Tiger Woods and Vijay Singh from joining Carl Pettersson at the top  USPGA Championship leaderboard.
                                
Tiger Woods: Happy with his short game 								     
 
 
Former world number one Woods, who is looking to win his first  major since 2008, made three birdies and two bogeys to finish at  one-under par for a total of 140 while Singh was the only player to  break 70 all day with a 69. 
Petterson, meanwhile, opened up with a 66 on Thursday but a hat-trick of bogeys saw him slip to a second-round total of 74. 
Woods, though, had a chance for the outright lead, but a  three-putt bogey on the final green meant he had to settle for tied  first-place. 
"I thought anything even par or better was going to be a good  score - that was my goal and I accomplished that," the American said. 
"It was a tough, tough day. The ball is oscillating and the wind is blowing the putter all over the place. 
"My short game's been good. I've made a few changes and I've had a pretty good feel for it. 
"You can't short-side yourself out there. You've got to leave yourself on the fat side and give yourself some room. 
"And then some of these bunkers are not bunkers - they're either hard pan or mud." 
The 49-year-old Singh, who will become the oldest major winner if  he triumphs on Sunday, says his head is in a "better spot" after a  difficult few years. 
"I just started believing that I can do it," he said. 
"I was so, so negative for a long, long time - I had great sessions on the range and just couldn't take it on the course. 
"I made a little tweak to my swing during the British Open and my head is in a better spot. I'm more focused." 
England's Ian Poulter carded a 71 to find himself in fourth while  Northern Ireland's Rory McIlroy, who made a 75, and Welshman Jamie  Donaldson (73) are tied for fifth. 
"It took a little bit of adjusting to, I missed a few balls right  at the start but I was able to get into it and it was nice to make a  couple of birdies," McIlroy said. 
 
Open Championship runner-up Adam Scott found himself two shots  off the pace after the opening day, but he followed it up with a 75 on  Friday to be tied for seventh with Aaron Baddeley, Trevor Immelman and  Blake Adams. 
World number four Lee Westwood is heading home after a 77 saw him  finish at eight over while US Open champion Webb Simpson is also out  after following up his day one 79 with an even-par 72.
