21.   Huber, whose serve was shaky throughout the match, never had a chance.

22.   I think her second serve is better.

23.   If Rafter thought the serve was out, he might have.

24.   If the serve is long, it breaks one of the four other beams.

25.   It was as close to wrong as a serve could be, barely striking the intersection of service and sidelines, a cozy little corner and ... poof!

26.   Ivanisevic never had control of his game, or his emotions, and his vaunted serve was erratic.

27.   My serve is working very well, and the last two matches my concentration was right on.

28.   My second serve is much better.

29.   On the next point, Seles hit a backhand way long, and her serve was broken again.

30.   One existing system, called Cyclops, uses light beams projected along the back of the service box to judge whether serves were in or out.
