 Coop s an ex-ballplayer is now a peanut vendor, who takes too much of an interest in the game. But he s passed on his craze for baseball to his son, Christie. When his dad gets fired, Chris makes friends with the former team owner s niece (and her boyfriend Pete), and not only gets his dad s job back, but a batboy position for himself. With his dad s help, Christie begins to make a few suggestions here and there. And as a publicity stunt, the team makes him their youngest manager on record. But when Chris gets sick, Coop has to come to the rescue.
