Rory McIlroy has had a forgettable 2012 to date, but he is already on the road to turning that around as the first round of the 2012 PGA Championship in South Carolina is underway. After McIlroy's first 18 holes, he is sitting pretty, in a tie for second place at 5-under and just one stroke off the current lead.

McIlroy sank five birdies in his first 16 holes and didn't bogey once in his round. The current leader is Joost Luithen, who sits at 6-under through 12 holes. Joining McIlroy in second place are Gary Woodland -- who has also finished his round -- and Carl Pettersson, who is through 14.

There are still plenty of top players yet to tee off on Thursday, including Masters champion Bubba Watson and Phil Mickelson, who has had an even worse year than has McIlroy. Tiger Woods is currently at 2-under through 16 holes.
