I have two doubles partners (both good players I enjoy playing with) who both seem to have the same issue: They freeze. It happened just today. I was playing with a lady against the pro and another lady. At the end of one of the games (when she had not had a play on several balls that were rightfully hers), my partner asked the pro what she can do to be more "ready." As I understand her question, her problem is that she feels like by the time she figures out which of her two opponents is going to hit the ball and what they are going to do with it, the shot is already past her. A different partner has this same issue, and it is driving her nuts. Say I am serving or receiving, and she is at net. I follow one of my shots in. Say a lob goes over her head. She won't say anything or make any sort of move. Say a lob goes over my head and I call for a switch. She won't run it down or make any move. She says everything happens so fast that she feels she can't catch up. Both of these ladies have asked the pro to help them "defrost," if you will. I have heard him give the following answers at different times: (1) Split-step and be mentally ready to play whatever ball comes. (2) Watch your opponents when both are at net. Whichever one is looking like they're about to do something is the one who is about to do something. Then ignore the other one and focus on the one who is about to do something. (3) Be aware of what is going on with your partner rather than look ahead all the time. He compared it to driving. You have three mirrors, yet you never stare into your mirrors. You instead spend most of your time looking ahead of you. In tennis, you have three players. You never stare at any one player, but you take quick glances at all three, including your partner, to gather information. That sounds good, but the problems still persist. Here's my question: What else would help thaw these two partners so they learn to react to what is happening around them? Is it just a matter of having slow reactions to things in general, such that it is a problem without a solution?
