How do you handle someone that consistently hits his shots within a foot or 2 of the baseline and hard with topspin? I'm not talking about a pusher hitting moonballs that deep. I mean regular shots with topspin. The person I hit with today played in college and also used to teach tennis several years ago. Last time we played just hitting cross court and to each other I could keep up because his shots were landing just past the service line. With the deeper shots I kept backing up several feet and moving back in. Am I supposed to just camp out way behind the baseline? That doesn't seem right either. This is not in a set type situation, but just feeding balls from the baseline.
