If you're the type of player who needs to be more aggressive or play closer to the baseline, try the "wipe the mark" drill. In this drill, one player (practice partner or coach) moves his opponent around the court with medium-paced balls. The object is not to kill the opposing player but to move the ball around with controlled shots. The practicing player (principal) must wipe ten (or more) marks during the rally with his foot. So, wherever the ball bounces on his side, the principal hits the ball and then immediately wipes the mark that was left on his side by the previous ball; and so son until the principal has wiped ten marks. After the players improve at this game, the principal can try to wipe ten consecutive marks.
This game teaches players to not only anticipate where the ball will land (so that the principal doesn't have to much court to cover between the contact point and the mark) but also builds confidence in standing closer to the bounce (so that the player is only a couple of steps from the ball bounce). Since the ball bounces inside of the baseline, the principal learns to become efficient with his strokes, footwork and balance. Lastly, the since the contact point is usually behind the mark and the principal must step forward in order to wipe it, the principal also learns how to move forward after every shot (thereby, perhaps, transitioning body-weight into the ball) before recovering back to the center. Therefore, this is not only a good drill for hand-to-eye coordination but also for developing aggressive footwork.,
