The 2003 Open Championship was Curtis' first appearance in a major. He became the first golfer since Francis Ouimet in the 1913 U.S. Open to win his major championship debut, later accomplished by Keegan Bradley in the 2011 PGA Championship. After his victory, Curtis jumped from 396th in the world rankings to 35th. This victory and a solid first season on the PGA Tour led to Curtis being named the 2003 PGA Tour Rookie of the Year. Curtis was the lowest-ranked player to win a major since official world rankings were first calculated.
