Serve is the most important shot in tennis (Cauraugh, Gabert & White,1990; Bahamonde, 2000; Elliott & Wood, 1983). One of the most important factors, affecting tennis serve performance is the ball toss. One parameter, which is not mentioned as in recent literature, is the eye contact with the bal. in which the player must always gaze at the ball from the very beginning of the toss. Some players avoid visual contact when tossing the ball and then start looking for it in the air. One other common mistake is when players take their eyes off of the ball and look at the court. That means he just dropped his head, which causes instability in serve.
