Top seed Miles Russell was eliminated from the 2026 U.S. Amateur Championship during the Round of 64 on Wednesday [1].

The early exit of the tournament's highest-ranked player disrupts the expected bracket and signals a wide-open competition at one of golf's most historic venues.

The match took place on Aug. 12 at the Merion Country Club in Ardmore, Pennsylvania [2]. Russell entered the tournament as the No. 1 seed, making him the favorite to advance deep into the championship [1]. However, he fell to Ryder Cowan in the opening match-play round [1].

Merion Country Club served as the backdrop for the Round of 64, where the field was narrowed through a series of head-to-head matchups [1, 2]. The elimination of the top seed is a rare occurrence in the early stages of the event, an outcome that shifts the momentum toward the remaining contenders.

Highlights from the round showed the competitive nature of the match-play format, where a single mistake can lead to immediate exit [1]. While Russell was the favorite heading into the event, Cowan managed to navigate the challenges of the Merion course to secure the victory [1, 2].

Tournament officials and spectators witnessed the upset as part of the wider Round of 64 action. The event continues to progress as the remaining golfers compete for the prestigious amateur title in Pennsylvania [1, 2].

The elimination of the top seed in the first round of match play highlights the volatility of the U.S. Amateur format. Unlike stroke play, where consistency over several rounds determines the leader, match play allows a single opponent to neutralize a ranking advantage, often leading to high-profile upsets at prestigious venues like Merion.
