McIlroy and Westwood will attempt to create history at the U.S. Open — both competitors are coming into the Open with successful tour event victories. Westwood recently won the Nordea Masters title in Sweden and seeking the first major of his PGA career.

Rory McIlroy 2011 winner of the U.S. Open set a record (-16) in the 2011 U.S. Open. McIlroy is riding a wave of momentum after winning the St. Jude Classic. Recent tournament victories posted by Westwood and McIlroy will be historic if one of the two leading competitors are victorious in the tournament. According to Bill Hanstock of SB Nation, “No golfer in history has ever won a tour event and the U.S. Open in back-to-back weeks.”

Rory McIlroy (2011) and Graeme McDowell (2010) became the first pair of non-American golfers to win back to back U.S. Open’s since Fred Mc Leod completed a run of 8 straight U.S. Open wins for Scotland in 1908. Americans will be looking to Woods, Mickelson, or Watson to stop the international reign and bring the trophy stateside.
