Jason Dufner has matched a major championship scoring record with a 7-under 63 in the second round of the PGA Championship.
Dufner had a golden chance at history, sticking his second shot within 12 feet of the flag Friday on the tough closing hole at Oak Hill.
But, perhaps realizing the significance of his round for the first time, he left the putt 18 inches shy of the cup.
Still, Dufner became the 12th player to shoot 63 in the PGA Championship.
Steve Stricker was the most recent to do it, in the opening round two years ago at the Atlanta Athletic Club.
Overall, this is the 26th time a player has shot 63 in a major.
It has been done at all four of golf's biggest events.
