If his competitors had hoped Rory McIlroy would repeat his Masters Sunday performance and meltdown, they are in for a rude awakening. McIlroy began his final round at the 2011 U.S. Open with a birdie, and is now 15-under for the tournament. McIlroy has a nine shot lead over his closest competitors, playing partner Y.E. Yang and perpetual majors bridesmaid Lee Westwood.

The low round of the day currently belongs to South Korean Sang Moon-Bae, who had six birdies and two bogeys on his way to a final round 67. Four other players in earlier pairings carded a 68.
