How often have you been the spectator in your doubles match, watching your teammate rally cross-court with an opponent, over-and-over? It happens all the time and it’s usually not the right play. The person with the least time to react to a shot is standing right at the net. Your goal in doubles is to move in and pick on the net person. Hit it low and at her feet. You’re not going to win that shot but it puts you in position to get a high volley and win the point.
