Rafa Nadal slicing (2009). Nadal is an expert in passing shots; they are an important part of his playing style. The slice is a very effective way to make a passing shot from running.
A passing shot is a forceful shot, as in tennis or team handball, that travels to one side out of the reach of one's opponent. In tennis, this shot is generally a groundstroke and is used when one's opponent is running to the net or if he is at the net already. The alternative to a passing shot is to lob the ball over the opponent's head.
