Keegan Bradley is the 2011 PGA champion.

PITTSFORD, N.Y. -- Keegan Bradley is threatening to become the second player this week to tie, or maybe break, the major championship scoring record of 63.
Bradley started the final round of the PGA Championship 3 over but has gotten to 3 under with birdies on his last three holes. He's 6 under for the day on the par-70 Oak Hill layout with five holes remaining.
Bradley, who won the 2013 PGA Championship, birdied his first, third and fourth holes on the front nine to turn in 32. He needs a birdie to tie the record and two to set it -- providing he doesn't drop any shots.
Jason Dufner became the 24th different player to shoot 63 on Friday during the second round. He left a 12-footer for birdie on the 18th hole about a foot short or he would have shot the first 62.
Dufner's 63 also broke the Oak Hill course record that was held by Ben Hogan, Curtis Strange and Webb Simpson. Simpson had finished off his 64 a few hours earlier.
A 63 has now been shot 26 times in a major championship.
