Tired of the same-old cross-court routine?! If so, here is a variation on the drill to keep things fresh and exciting. Two players are in opposite corners rallying cross-court. One or two coaches (one on each side of the net in the middle of the service box) is positioned in front of the baseline player(s) at the net. Two coaches would be available when players are drilling against each other during a tournament. Without moving too close to the middle of the court (i.e. center line), the coach(es) attempt(s) to intercept the cross-court ball that is struck by the opposing baseline player. When intercepting the ball, the net player/coach makes the baseline player chase the the ball (either drop shot or to the opposite corner; the rally must continue). The key is not to intercept too many balls; just the easy ones...the ones floating too close to the middle of the court.
Why is this variation important? First of all, most players do not have the discipline to group their shots in a designated cross-court area. Often times, their shots wander into the middle of the court, sail wide or float deep. Having a person at the net who's trying to steal your shots reminds you to "keep the ball out of the middle of the court" and to channel into deep into the opposing corner. Second, this drill is also (and obviously) important for doubles. In doubles you are faced with a net player who is trying to intercept your shot. This keeps you sharp. Float the ball a little too close to the center and you (and your partner) are toast/tagged. So, in other words, this is a great way to use a "doubles practice" to sharpen your singles game.
