SOUTHAMPTON, N.Y. – Jackson Koivun concluded his amateur golf career Sunday at the 126th U.S. Open by clinching a share of low am and tying for 23rd place with a final score of 5-over-par.
Koivun shares low amateur honors with Oklahoma’s Ryder Cowan.
He fired rounds of 72 (+2), 71 (+1), 74 (+4) and 68 (-2) to make his first career cut at a major championship. Overall, it was Koivun’s eighth cut in 10 starts.
The Chapel Hill, North Carolina native broke out his Sunday best in the fourth and final round. He shot 32 (-3) on the front with back-to-back-to-back birdies on the third, fourth and fifth holes. He bogeyed 10 and 15, but those were his only blemishes on the card. He put the cherry on top with one final birdie on 18. His 2-under 68 is the lowest final round by an amateur at the U.S. Open since Viktor Hovland shot 67 (-4) in 2019.
Wyndham Clark won the U.S. Open with a score of 4-under-par.
Up next, Koivun takes a week off to prepare for his professional debut, which is set for the following week, July 2-5, at the John Deere Classic at TPC Deere Run in Silvis, Illinois.
