He won 13 times on the PGA Tour between 1997 and 2001, the last of these wins being the 2001 Open Championship at Royal Lytham & St Annes.
Known as ‘Double D’, he also won a number of other events around the world, including the 2000 WGC-World Cup, with Tiger Woods.
After winning the Players Championship in March 1999, his third win in under three months, he became World No 1, displacing Tiger Woods and holding the position for 14 weeks. He held the No 1 spot a second time, for just one week, that August.
Following his Open Championship win and a title in Japan in November 2001, Duval lost his form completely through a mixture of injuries and personal problems, and has not won since, although he surprised everyone with a tie for second in the 2009 US Open.
In the 1999 Bob Hope Chrysler Classic, Duval became only the third player in PGA Tour history to shoot 59, and the first to do so in a final round, eagling the 72nd hole to clinch victory.
