In a short period Northern Irish golf prodigy Rory McIlroy has gone from winning the European Amateur in 2006 and topping the World Amateur Golf Rankings in 2007 to winning his second major championship at age 23. He became the youngest to win two majors since 1980 (Seve Ballesteros) and joined Jack Nicklaus and fellow Upper Deck spokesperson Tiger Woods as the only players to win six PGA tournaments by the age of 23. Not only is Rory winning these events, he is rewriting the record books. Rory ran away with the U.S. Open in 2011 with a tournament-record 16-under par for an eight-shot victory. McIlroy then won the 2012 PGA Championship by a tournament-record eight shots as well. His legacy grows with each spectacular performance. Rory has been labeled the most exciting young player in golf and one of the most marketable.This white embroidered 2011 #18 U.S. Open pin flag has been signed by Rory McIlroy in black paint pen.
