What is a ace in tennis?

In tennis, an ace is a serve that the receiver is unable to touch with their racket, resulting in a point for the server. Aces are typically served with a high speed and precise placement, making them difficult for the opponent to return.

Aces are highly valued in tennis as they are essentially free points and can help players gain momentum in a match. Some players, known for their powerful serves, are particularly skilled at hitting aces consistently.

The record for the most aces in a single match is held by John Isner, who hit 113 aces in a first-round match at Wimbledon in 2010. Roger Federer, Goran Ivanisevic, and Ivo Karlovic are among the other players known for their ability to hit a high number of aces in a match.
