If you were asked which player in the field at Oak Hill was primed to tie the major record for lowest-scored round, how many guesses would it take to get to Jason Dufner?
The 36-year-old with two career PGA Tour victories soared to the top of the leaderboard Friday, catching fire en route to a seven-under-par 63. No player in history has ever compiled a better score at a major tournament.
Dufner, who coughed up a five-stroke lead with four holes left at the 2011 PGA Championship before falling to Keegan Bradley in a playoff, enters the weekend in control. He sits at nine under for the tournament, leading a trio of players by two shots.
His amazing Friday afternoon effort quickly dawned on Dufner afterward.
''The history of the game is something dear to my heart,'' he told AP writer Paul Newberry via Yahoo!, ''To be part of history, to be there forever, is a neat accomplishment. I never thought a guy from Cleveland, Ohio, would be able to do the type of things I've been able to do.''
