The 111th U.S. Open begins Thursday, June 15th, at the Congressional Country Club in Bethesda, Maryland.

The most famous golfer in the world, three-time U.S. Open champion Tiger Woods, won't be playing due to an injury to his knee and Achilles tendon.

However, there are still other storylines and players to watch.

American Phil Mickelson is looking to win his first U.S. Open against a very strong field featuring the two top-ranked players on the Tour, Englishmen Luke Donald and Lee Westwood, ranked first and second, respectively. German-born Martin Kaymer is third in the world, and seeking his second PGA Major title.

One player to watch for in the tournament is 22-year-old Rory McIlroy from Northern Ireland. Currently ranked number eight in the world, he blew a big lead at the Masters in April and eventually finished 10 strokes behind winner Charl Schwartzel.

Just ahead of McIlroy in the world rankings, and also competing at Congressional, is fellow countryman Graeme McDowell who was the winner at last year's U.S. Open.
