I was asked for the best advice for the partner during a crosscourt rally so here is the pro, best in the world, poop on that role:
This subject came up during our Mixed Doubles class last night. Now that she is fearless with her new Oakley polycarbonate eyewear, and doesn’t mind a bruise or two (or three!), Jill prefers to build a fort at the “O” (a chalk mark I put in the very middle of the service box which stand for “offense”) while her partner plays from the baseline during a cross court rally (unless she knows the opponent will tag her).
Despite Jill’s fantastic reflexes at the net and intimate knowledge of her opponent, I prefer she go back to the “Star” (a chalk mark I put at the middle of her service line on my teaching court) in mixed or women’s doubles. This prevents lobs from going over her head so that her partner can come forward without worrying that they need to cover that shot.
The Bryans, Hingis/Mirza (1), and Mattek-Sands/Safarova (2) have all discussed the role of the partner in interviews when the crosscourt baseline rally is going on. That role is huge in pro doubles.
The “home” for the pros who are partners during a baseline rally is the “O” or the “Star” (see above)—> HOWEVER—they run from the Star to the center line, to the O, depending on the quality of their partner’s/opponent’s crosscourt shots. They do this EVERY time the ball crosses the net! They are that mobile because they are trying to intimidate the baseliner into an error or make them change their shot to down the line. The best poach for winning volleys. This kind of constant movement requires a LOT of off court preparation.
The best players in the world say they get a lot more tired than the baseliner so, unless you have Sania Mirza’s forehand groundstroke, to prevent the wear/tear on the partner, the pro baseliner should come forward ASAP. Even Sania knows she has to make something happen so Martina doesn’t melt doing all that footwork!
Recreational Tennis: if that kind of effort can not be put into every crosscourt rally by the partner, both on the Star ready to go to the O is best (or both back second best) but the team should ALWAYS try to avoid being extremely split by one being at the O and one on the baseline. Make sense?
