Following the catch, a nice throw to first base is required. The first baseman then pitches to the catcher. If a ball is missed, the player who missed it rushes and gets it. Then he returns and rolls the ball into the backstop as the rest of the team continues with the practice. This throws off the batter so they don't know where the ball is hit to them allow them to make their own break and run strategy. The purpose of this drill is to develop speed and accuracy on the part of the players. It can be done as part of a practice session or as stand-alone work. Since the objective is to have the pitcher throw to first base, she should do so while the hitter is standing still. The first thing you will need for this drill is a baseball or softball. Next, you will need at least one other person who will be acting as first base. You could use a friend or family member to act as first base. If you don't have anyone available, then an actor from a local sports theater group may be willing to play the role for some money. Finally, you will need a coach who will be calling out instructions to both the hitter and the pitcher. The more people involved, the better since there are more opportunities for things to go wrong.
