The drop shot has the same stroke preparation and set up as for your normal forehand and backhand. You should have the same backswing and shoulder turn as your normal forehand and backhand. The body motions are the same. Shift your weight in the same manner. Do not adjust your forward racquet head speed or positioning of the racquet until the last possible second. Show the same upper body and facial emotions the exact same way as when hitting your ground strokes. Do not alter your style before making contact with the ball. Some coaches say you do not have to change your grip. Other coaches, including me, recommend a grip change to more of a continental grip if you have a full western grip on your forehand or backhand. But if you have a full western and are having success with that grip, then I would say do not change.
Because of the power in the game today, many times one of the players will be forced into defensive positions well behind the baseline. The drop shot is extremely effective in this situation. It will make your opponent defend the entire court, not just the deep part of the court. There are other times when a change of pace is needed to get a player out of his/her groove. A drop shot is an excellent choice for this situation.
When an opponent has a weak volley or overhead, a drop shot can effectively be used to draw the opponent into the net to then pass him/her, or lob him/her. When you’re facing a slow or weary opponent, they are perfect candidates to be drop-shotted. If you notice either of these conditions, move them side to side, give them high deep balls, then when they reply with a defensive reply, hit a drop shot.
When you see that your opponent is a confirmed baseliner who moves well side to side but doesn’t move as well forward or backward, they are candidates for the drop shot. Many times you might find that a baseliner opponent might be uncomfortable moving forward or uncomfortable in the territory near the net. They are likely to go off their steady way of getting everything back when you give them short slices, angles, and drop shots. Some players fear the net. Drop shots can be used to bring them in and force them to hit a volley or overhead.
