Jason Dufner cards a 63 at PGA Championship

Jason Dufner fires a 63 in the second round of the PGA Championship at Oak Hill in Rochester, NY. today to card a two-day total of 131, good enough for 9-under par and a two-stroke lead over Adam Scott, Matt Kuchar and Jim Furyk as the tournament heads into the weekend.

Dufner flirted with history to become the first golfer in a major tournament event to shoot a round of 62, but came up just a little short on a birdie try on the 18th hole at Oak Hill.

Tiger Woods (71-70) struggled all day as the putts wouldn't fall and finished even-par today and a 1-over, two-day total of 141 for the tournament -- 10 strokes behind!
