The fourth round of the 2012 PGA Championship has wrapped up, and it was the young Rory McIlroy who completely dominated the competition. McIlroy shot a -6 on Sunday, improving his overall score to -13 for the tournament. His margin of victory over the second place finisher, David Lynn (-5), is the largest in PGA Championship history, breaking Jack Nicklaus' record.

The win marks the second major championship win of McIlroy's career. He will remain the No. 1 player in the world.

Tiger Woods remained in the hunt through late Saturday, but a poor finish to round three and a slow start on Sunday dropped him back on the leaderboard. Woods finished at -2 overall after shooting par today. His wait for a major championship will continue on to 2013.

Justin Rose, Keegan Bradley, Ian Poulter and Carl Pettersson all tied for third place at -4 overall.
