Why do players follow through on the wrong side of the body?
The follow through after serving, the reason you see players do this is their striking the ball with what we call a kick serve, or topspin serve. the movement of the racket and the arm is up and out to the right, if you’re right-handed player. the arm pattern or path of the racket finishes to the side of your body, that’s why you see pictures in the magazines with the players and their arm out to the right after serving.
