Jackson Koivun

Jackson Koivun won the Mark H McCormack Medal as the leading male in the 2025 World Amateur Golf Ranking® (WAGR®), earning with it an exemption for The 154th Open.

His outstanding results in the amateur ranks, including victory in the SEC Men's Golf Championship Stroke Play, earned professional opportunities, and the Californian would make his mark during an impressive summer in 2025.

He recorded three consecutive top-10 finishes on the PGA TOUR – T6 at July’s ISCO Championship, T5 at the Wyndham Championship in August and T4 at the Procore Championship the following month.

Koivun made his major debut in the US Open at Oakmont County Club earlier the same summer, before starring for the US in their Walker Cup victory at Cypress Point.
