Jason Dufner scrambled for a par on the ninth hole Sunday to head to the back nine at the 95th PGA Championship with a 2- stroke lead.
Dufner saved par from 11 feet out on the seventh before nearly dunking his approach for eagle at the eighth. He kicked in a short birdie try to move to minus-11, where he was one clear of Jim Furyk.
At the ninth, Dufner found the left rough of the tee, then came up short with his second. He chipped to eight feet and converted that par putt to take the lead to the back nine.
Furyk got up and down for par on seven, then 2-putted for par from seven feet out on the eighth. The 2003 U.S. Open champion missed the green at the ninth, and that led to a bogey, which dropped him two back with nine to go.
Henrik Stenson remains alone in third. He was 1-under through 10 holes to stand at 8-under par for the championship. Masters winner Adam Scott is also 1-under for his round and is alone in fourth at minus-6.
Scott Piercy owns the clubhouse lead at minus-5 after he closed with a 5-under 65. That 65 included two bogeys in the last four holes.
Four-time champion Tiger Woods went out in 3-over 38 with a bogey at eight and a double-bogey at nine. Around the turn, he birdied three of four holes from the 12th to get back to even-par for his round. Woods parred the last three holes to finish at 4-over 284.
Miguel Angel Jimenez poured in five straight birdies from the 12th to the 16th en route to a 3-under 67. That was the second time this week that Jimenez birdied five in a row, as he also did it in the first round from the second to the sixth. The Spaniard ended at 2-over 282.
Tim Clark, who finished third at the 2003 PGA at Oak Hill, recorded the first hole-in-one of the week. He aced the par-3 11th, but still struggled to a 75, which left him at plus-10.
British Open champ and Phil Mickelson mixed four birdies, a triple bogey, a double bogey and a bogey in a round of 2-over 72. The 2007 PGA winner ended the tournament at 12-over 292.
