US Open 2015: Rory McIlroy and Martin Kaymer paired together

Martin Kaymer has won two majors, the 2014 US Open and the 2010 PGA Championship

World number one Rory McIlroy has been paired with defending champion Martin Kaymer of Germany for the first two rounds of the US Open at Chambers Bay.

They will be joined by US amateur champion Gunn Yang of South Korea when the season's second major gets under way near Seattle on Thursday.

Northern Irishman McIlroy, 26, won the title in 2011 and is the reigning PGA Championship and Open champion.

Tiger Woods, 39, will play alongside Rickie Fowler and Louis Oosthuizen.

Woods is aiming for a 15th major title and fourth US Open success, less than two weeks after shooting the worst round of his professional career at the Memorial Tournament in Ohio.

Six-time runner-up Phil Mickelson, who needs to win the US Open to complete the career Grand Slam having already won three Masters titles, one Open and one US PGA Championship, has been paired with 2007 winner Angel Cabrera and Bubba Watson, twice Masters champion.

Jordan Spieth, who won the Masters in April, will tee off alongside 2013 US Open winner Justin Rose and twice runner-up Jason Day on a course hosting the tournament for the first time.
