Serving with Spin
Hitting the serve with spin allows you to hit the ball with a higher degree of safety as well as adding some deception. By deception I mean that spin forces your opponent to watch the ball longer and more closely. He needs to know which way the ball is bouncing. Many receivers slow down or shorten their return when they see a spin serve coming. If the receiver cannot tell your spin serve from your flat serve you should serve a lot of aces.
There are four basic serves: flat, slice, topspin and twist. (There is also the underhand serve which many players refuse to use because they feel it is unethical, unfair or a cop out. It is very useful if you have a sore shoulder or the sun is in your face.)
The slice serve is the easiest and most common spin serve. If you use the continental grip and you toss the ball right over your head, you will hit a moderate slice. It will bounce a little to the left if you are right handed or a little to the right if you are left handed. To get more slice, you can hit across the ball or you can toss the ball farther to the right (if right- handed). The latter is a giveaway to the receiver, but only if he is aware and paying attention.
Topspin. The topspin serve is the most popular spin serve. Good players use this serve to hit an aggressive second serve by going to the backhand side which is usually weaker for most players. This serve clears the net higher and bounces higher than the flat or slice serves. To hit the topspin serve it helps to toss the ball over your head or to the left. This makes it easier to hit up the back of the ball. For this serve, focus on the feel of your racket. Imagine it going from left to right and up on the ball. One pro tip is to accelerate the racket more through the contact point. If it goes into the net you are probably throwing the ball too much in front of you.
Another Variation is the Twist. Twist Serve
The (American) twist serve is a topspin serve that bounces to the right if you are right handed (left if you are left handed). Since the normal right handed serve bounces to the left, the twist serve confuses the receiver by bouncing to the right. To hit the twist serve, toss the ball to the left of your head. If 12 o’clock is over your head, toss the ball to 11 o’clock. Then swing across the ball from left to right. (Reverse for left handers. Avoid bending your back or you risk injuring your back.This serve is easier if you are are young and jumping into your serve.
