In
tennis, an
ace is when you get a point on one
swing. There are two types of commonly referred to aces:
Service Ace, and
Return Ace. A service ace (or simply ace), is when the ball is not returned from the
serve. These are very difficult to accomplish.
A Return ace is when the ball is returned from the serve in such a way that the server cannot volley the ball back to the
opponent. These are tough, and are definate crowd pleasers in most high tension matches.
