"I had a good number in with my wedge after finally hitting the fairway on [the 18th hole]. I put a good wedge shot on it, and luckily, I two-putted and got away with the win," noted Groppuso.

On the par-4 17th, Groppuso two-putted from above the hole on No. 17 to secure his par, while Cavaliere short-sided himself left and could not get up and down for par. With the match tied heading into the 36th hole, both competitors found the fairway off the tee.

Cavaliere's ball came to rest in a divot, and his ensuing approach shot spun off the front of the green; Groppuso's second shot on 18 landed about 12 feet above the hole. Cavaliere chipped to inside six feet; Gropposure then left his putt inside of two feet which was conceded. Cavaliere set up for par to attempt to extend the match but the just skirted the hole, ending the match. 

Groppuso, with his younger brother Gavin on the bag, was two down after the first three holes of the afternoon 18. The 22-year-old made par on the par-4 seventh before birdieing the par-5 ninth after his approach came to rest a foot from the hole.

"I dreamed of having this opportunity to win something big like this at the highest level as an amateur and spending it with [my family]," said Groppuso, who is heading into his senior year at Florida Southern College. "Especially my little brother. Being able to hug him as my caddie, there are no words to describe it."

In the morning 18, 14 of the 18 holes were won. Cavaliere won five on the opening nine to lead 4-up at the turn. Cavaliere built his 4-up lead via a run of four birdies in a row on holes three through six.

Groppuso won five of the first six on the back and the 18th, leveling the match. After Cavaliere won No. 12, Groppuso won No. 13, and 14 with pars before leveling the match with a lengthy birdie putt on No. 15.

With his win in the Met Amateur, Groppuso is exempt into the U.S. Amateur, which Hazeltine National Golf Club in Minnesota will host starting on August 12.
