ROCHESTER, N.Y. -- On a day in which more than 30 players shot in the 60s, including two who threatened the all-time major championship scoring mark, Tiger Woods was left spinning his wheels in soft, muddy conditions at Oak Hill Country Club.
The world's No. 1 golfer will have to make up a slew of ground to win his 15th major title here, as he could do no better Friday than even-par 70, which left him 10 strokes back of leader Jason Dufner through 36 holes at the PGA Championship.
"I didn't hit it anywhere near as good as I did yesterday,'' Woods said afterward. "Consequently, I didn't have that many looks. When I did, I missed my share, too.
"Just the way it goes. Obviously, I need to hit it better than I have, obviously keep the ball below the hole so I can be aggressive with the putts.''
The largest 36-hole deficit Woods ever has overcome to win a major was six strokes at the 2005 Masters, where he shot 65-71 on the weekend to tie Chris DiMarco, whom he then beat in a playoff. On the PGA Tour, Woods overcame a nine-shot, 36-hole deficit at the 1999 Buick Invitational to win, shooting 62-65 on the weekend.
Among the issues he faces here is he's tied for 39th. And then there is the matter of his play; Woods simply is not giving himself enough chances. He hit only seven of 14 fairways and 13 greens Friday, but he three-putted twice – including the par-4 14th, on which he drove the green -- and also at the 16th.
After making just two birdies on Thursday, Woods made four in the second round but also had four bogeys.
"I'm going to have to do my job and shoot a good round,'' he said. "But also, then again, I'm so far back that if the leaders go ahead and run off with it and shoot a low one tomorrow, I'm going to be pretty far behind.
"I've got to do my job tomorrow and go out there and post something in the mid- to low 60s, like some of the guys did today. It definitely can be done.''
Woods is coming off a strong performance last week at the WGC-Bridgestone Invitational, where he shot a second-round 61 and cruised to a seven-shot victory, the 79th of his PGA Tour career. Oak Hill has been far less friendly to Woods, who in six careers rounds here has failed to shoot in the 60s.
Woods has five victories this year on the PGA Tour and eight in the past two seasons. He has not won a major since the 2008 U.S. Open.
