In tennis what is the difference between a baseline player and a volley or serve player?

a baseline player, literally keeps the ball at the baseline. he focuses on keeping hr depth of the ball very deep into the court, near the baseline. this can be a good tactic, or a very bad one.. depending on the situation. and serve and volley, once again literally: serves and sprints to the net. they make the serve so explosive in force, that when they find themselves done with the serving motion, theyre halfway into the court, and have no choice but to play at the net. hope this helped
