Dunlap, who was the only amateur competing in the event, is just the seventh amateur since 1945 and the third since 1957 to win a tour event. The last amateur winner was Phil Mickelson in the 1991 Tucson Open.

After the event, Mickelson gave Dunlap props on social media.

Such an impressive performance by Nick Dunlap. Congratulations on an incredible win. This is just the beginning 👍👍

Dunlap's monumental win comes with stipulations, however. He won't earn prize money because of his amateur status, per PGATour.com. Regardless of whether he decides to turn pro following the event, he will not earn prize money, nor will he earn FedEx Cup points. Instead, the prize money will go to Bezuidenhout, who finished in second, and the points will not carry over to anyone.

Whether he decides to go pro this year or keep his amateur status, it's clear Dunlap is on his way to a great career.
