Jackson Koivun, 20, of the United States of America has won the Mark H McCormack Medal as the leading male in the 2025 World Amateur Golf Ranking® (WAGR®).
The McCormack Medal winner receives exemptions next year into the US Open at Shinnecock Hills and The 154th Open at Royal Birkdale.
Koivun said, “It’s a huge honour to win this award. I’m very grateful to everyone who has helped me and it’s a dream come true. It’s a medal every amateur golfer strives for.
“It’s in the back of everyone’s head and you just try and fight and keeping playing well. To be able to say I’m a McCormack Medal winner is just really, really cool.”
Impressive results
The American, who lives in Chapel Hill, North Carolina, has built on his successes last year to reach the top of the world standings.
Koivun's freshman year at Auburn University in 2024 was one of the best seasons in collegiate history. Last year he won the SEC Championship and only finished outside the top-six once in 13 starts. He became the first player to win all four major collegiate awards (Jack Nicklaus, Fred Haskins, Ben Hogan and Phil Mickelson Awards) in the same season. As a freshman, he posted a 3-0 match play record to help Auburn claim its first-ever NCAA title, while finishing a stroke out of the top spot individually. Koivun was selected to represent the USA in the Arnold Palmer Cup in 2024 and did so again this year.
In 2025, he has won the SEC Men's Golf Championship Stroke Play and the NCAA Auburn Regional, as well as finishing runner-up at the Mason Rudolph Championship. Koivun’s amateur achievements have helped secure professional opportunities and he qualified for his major debut at the US Open in June and has since impressed by securing three finishes inside the top-12 at the John Deere Classic, ISCO Championship and Wyndham Championship on the PGA TOUR.
