In tennis, an ace is a legal serve that is not touched by the receiver, winning the point. In professional tennis, aces are generally seen on a player's first serve, where the server can strike the ball with maximum force and take more chances with ball placement, such as the far corners of the service box. According to the International Tennis Hall of Fame, this term was coined by the sports journalist Allison Danzig.
Professional singles records
Aces have been officially recorded by the top-level professional tennis circuits since 1991, so these records start at that time.
Only main draw singles matches are included here.
John Isner has the most aces in a tournament with 214 during the 2018 Wimbledon, and he has the most in a single match with 113 during his 11 hour encounter with Nicolas Mahut. He is also second on the career list.
Ivo Karlović has the most career aces with 13,552. He also has the most in a best-of-three-set match with 45 at Halle in 2015. Two weeks later, during Wimbledon, he became the only player to hit at least 40 aces in three consecutive matches.
