When coaching baseball, coordinating who takes a pop up is a major issue. This play can lead to embarrassment or worse, serious injury. The basic key is that the player who lines up the greatest distance from the plate takes charge and handles the play. For example the 3rd baseman lines up farther from the plate than the catcher, so when he feels he can catch the ball he should shout, ball, ball, ball to let everyone know he has the play. Others around the point where the balls coming down should shout take it, take it, take it, to let him know he’s safe to make the play. Here is the link to the drill we use.
