US Open men's singles ace rate falls to ten-year low

The 2026 US Open is experiencing a noticeable decline in aces, with the current rate tracking at 8.7% through 44 completed matches. This figure represents the lowest ace frequency at a hard-court Grand Slam since the 2012 Australian Open. Analysts attribute the drop to the specific physical characteristics of the Wilson Extra Duty balls used at the tournament, which absorb moisture and expand in New York’s high humidity. This process increases the weight of the ball, causing it to travel slower and land shorter, which makes it easier for returners to handle serves. Environmental variables in Arthur Ashe Stadium, including indoor air circulation and fluctuating temperatures, further complicate the ability of players to generate consistent speed. While the US Open historically records fewer aces than other majors, the current tournament performance sits well below the established baseline.
