The USGA announced earlier today that Sean O'Hair has withdrawn from the U.S. Open, citing a pulled chest muscle. O'Hair was advised by his trainer not to compete with the injury.
England's Gary Wolstenholme will take O'hair's spot as first alternate. Interestingly, Wolstenholme is the last player to have beaten Tiger Woods when he was an amateur (1995 Walker Cup). He's 47.
