He famously won the 1989 French Open after defeating Ivan Lendl in a five-set battle using an underhand serve. Although unconventional, the rules allow for underhand serving in tennis. As long as the ball is hit with the racquet prior to hitting the ground, it doesn’t matter if it was released in an upward or downward motion. ADVERTISEMENT . This rule can be found in the Friend at Court under the ITF Rules of Tennis #16 The Service. **
To hit a successful underhand serve, players must go through the early stages of the serve motion as normal, but, prior to the point at which one would lift the non-racket arm above the waist to toss the ball, he must bring the racket forward with the head pointing downward, release the ball with the hand below hip-height and hit it with an underhand motion.
not a big deal at all, if you can't deal with a slow paced high spin underhand serve then sucks for you. I don't think it should be taught but if for some reason you are injured or cannot preform a normal serve, then an underhand serve is fine. However you can't drop and hit the serve if I remember, like any other serve you toss it up and hit it.
Although less widely used than the other main types of serves, the underhand or underarm serve is considered a legal serve according to the official rules of tennis. Famously, Michael Chang defeated Ivan Lendl in the 1989 French Open by using an underhand serve.
For each point, the server has two attempts at the serve. If the first serve lands in the service court, that is the ball that’s played. If the first serve lands outside of the service court or goes into the net, it is a fault and the server has a second serve. If this second attempted lands in, the ball is played.
The other reason is a matter of ethics: Underhand serves are perfectly legal -- the International Tennis Federation (ITF) Rules of Tennis (#16) says only that the ball must be struck "before the ball hits the ground", and the United States Tennis Association adds a comment (#16.1) that a player may serve underhand as there is "no restriction in the rules on the kind of service motion that a server may use."
In tennis, the underarm serve tactic is usually disparaged and has no esteem despite it being perfectly licit. The service can be a powerful weapon to the player, provided the player masters upon the drop-serve. Also, the service has an atypical spin and makes it little unusual for the receiver.
