An ace
Hmmm.....Second Serve Ace!
In tennis when the opposing player is unable to return the first serve, this is known as an ace. An ace is also a hole in one in golf, and obviously card games.
You can only be awarded an ace when you serve the ball.
ACE
It is called a service ace!
No, an ace is when you serve the ball so well that it can not be returned.
match, point, serve, ad out
No. The interior lines (half-lines) on tennis courts determine the service court, into which the serve must be made. An ACE is any legal serve that is not successfully returned by the opponent, winning the point for the server.
When the server serves the ball directly into the opposite side of the court with no player from the other team touching the ball (or they touch the ball but the second pass is unplayable).
There are two types of serve that a player cannot return, one is an Ace and one is just called Unreturnable. An Ace is when the returner cannot get their racket to the ball at all. An Unreturnable is when the returner touches the ball, but cannot return it within the court.
Serve, ace, smash, forehand, backhand, volleys, slice, top-spin, doubles, singles.
