In tennis, an ace is a legal serve that is not touched by the receiver, winning the point for the server. 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.
John Isner holds the professional records for most aces in a match Wimbledon 2010, an entire tournament Wimbledon 2018, and also first on the most aces in career list .
