Nick Dunlap became the first amateur in 33 years to win on the PGA Tour, making a 6-foot par putt on the final hole for a one-shot victory at The American Express on Sunday. Dunlap, the 20-year-old University of Alabama sophomore and reigning U.S. Amateur champion, is the first amateur winner since Phil Mickelson at the Tucson Open in 1991. He’s only the seventh amateur since 1945 — and the third since 1957 — to win a tour event. Dunlap surged into a three-shot lead with a sizzling 60 in the third round. He closed with a 2-under 70 to finish at 29-under 259.
