What is your “intent” when you return serve in doubles? If it is to win the point on that stroke, you are probably over reaching and making too many return errors.
Playing a good doubles match recently, it dawned on me: The return of serve is like an approach shot in singles… your intent is not to win the point on that stroke; but to set up the NEXT shot.
In doubles, the return is usually cross court and (hopefully) low; so the server coming in has to “volley up.” That is the signal for your partner to step into the middle and then put away the next shot.
If you lob, it should not be trying for a winner; but to drive your opponents off the net; you and your partner come to the net; and then take the offense away from the serving team.
Even if you hit at the net man, again, you should be looking for him to just block it back; then you, or your partner, attacks the short ball for the winner.
So in doubles, the returner is the “setup man” and his partner should be ready to play the role of the “put away player.”
I once asked Roy Emerson at camp, “What should be our goal for return of serve percentage in doubles?” His answer was “100% returns in play!” And he backed that up by telling me he did exactly that in a Wimbledon doubles final!
