Ace serve. Often just past the serve line and in the crack.
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.
If the player is unable to hit the serve then it is an ace. But if the player hits the ball but does not return it, then it is a forced error.
An ace serve occurs in tennis when the opponent does not even get his racket on the ball as it whizzes past him.
