David Robert Duval (born November 9, 1971) is an American professional golfer and former World No. 1 Golfer who competed on the PGA Tour. Duval, originally from Jacksonville, Florida, 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). Duval won 13 PGA Tour tournaments between 1997 and 2001. He won his sole major title at The Open Championship in 2001. After that point, due to injuries and medical conditions, his performance declined dramatically, culminating in the loss of his tour card in 2011. After his professional golf career slowed, he became an analyst and commentator.
Duval was born in Jacksonville, Florida, the son of golf instructor and club professional Bob Duval and Diane Poole Duval, a member of the FSU Flying High Circus during college. His brother Brent was two years older, and sister Deirdre was five years younger. During his early years, his father was club professional at Timuquana Country Club, where he learned to play golf under his father's guidance.
