David Robert Duval (born November 9, 1971) is an American professional golfer and former World No. 1 Golfer who competed on the PGA Tour and currently plays on the PGA Tour Champions. Duval won 13 PGA Tour tournaments between 1997 and 2001; including one major title, The Open Championship in 2001. Duval received his PGA Tour card in 1995, earning it after becoming two-time ACC Player of the Year, 1993 National Player of the Year, and playing two years on the Nike Tour (where he won twice). Between 1997 and 2000, Duval finished all four seasons top-5 on the PGA Tour's money list, including being the leading money winner and scoring leader in 1998. In addition to his major title, he also won the 1997 Tour Championship and the 1999 Players Championship.
