Rory McIlroy of Northern Ireland tees off on the 5th hole on day one of the US Open at San Francisco's Olympic Club on June 14, 2012 in California. The 112th US Open teed off early with Rory McIlroy bidding to become the first back-to-back winner of the year's second major since 1989, but all the anticipation was at the ninth tee for the day's marquee grouping of Tiger Woods, Phil Mickelson and Bubba Watson.
