Defending champion Tiger Woods won his fourth PGA Championship and 13th major title, two strokes ahead of runner-up Woody Austin.

Lengths of the course in previous major championships: Thursday, August 9, 2007 Graeme Storm led the field after the first round by shooting a bogey-free 65 (−5).

Other notable scores include: John Daly, currently ranked 423rd in the world, shooting a 67 (−3); Brad Lardon shot the best round of the day among those who qualified for the tournament through the PGA Professional National Championship by shooting an even-par 70; U.S. Open champion Ángel Cabrera shot a disappointing 81 (+11), largely due to a septuple-bogey 10 on the par 3 6th hole; Retief Goosen, the last major champion at Southern Hills (2001 U.S. Open), shot an even-par 70 including an eagle and a double-bogey.

The feat had been previously accomplished 22 times by 20 other players, and also tied the course record set by Raymond Floyd in the 1982 PGA Championship.

Local fan favorite and former Oklahoma State golfer Scott Verplank also had a good round with a score of 66.

However, his bogey on the 14th hole, coupled with Woody Austin's third consecutive birdie at the 13th, whittled Woods' lead down to a single stroke.
