College student Dunlap wins at PGA West but is ineligible for $1.5m first prize

• 20-year-old is first amateur winner on PGA Tour since 1991
• Status means first-place prize money has to be forfeited

Nick Dunlap became the first amateur in 33 years to win on the PGA Tour, holding on for a one-shot victory over Christiaan Bezuidenhout at The American Express on Sunday.

Dunlap, the 20-year-old University of Alabama student and reigning US Amateur champion, is the first amateur winner since Phil Mickelson at the Tucson Open in 1991. Playing in just his fourth tour event, he became only the seventh amateur winner since 1945 - and the third since 1957.
