Approach shot drill
This drill is a good drill to help you practice your approach shots.
The drillee starts on the baseline while the ball feeder starts on the other side of the court at the baseline. The drill starts by the feeder hitting a groundstroke to the drillee. The drillee returns the ball and the feeder returns a short ball. The drillee closes in and hits an approach shot down the line and closes the net. If the feeder can return the approach shot then play out the point.
Be sure to practice both the slice approach shot and the topspin approach shot. Also be sure to practice both the backhand and the forehand side.
