The leaderboard at the first round of the 2012 PGA Championship continues to shuffle around as Ken Duke has taken over the tournament lead after his opening nine holes at 4-under par.
Defending champion Keegan Bradley is now two-shots back from Duke after dropping a shot on his fourth hole. Tiger Woods has also fallen off the pace a bit and remains at even-par for the championship while still playing his opening nine holes.
Rory McIlory has moved up the leaderboard, however, and is now in a tie for second place at 3-under par. McIlory could use a strong finish this week to put pressure on the Official World Golf Ranking leader Luke Donald for the top spot on that list.
Gary Woodland and Carl "Don't Call Me Peterson" Pettersson are also one shot back from Duke. The morning groups will be finishing their front nine momentarily.
