That's where they meet Andy, whose dad, Josh Robinson, is an All-Star catcher. But before the Home Derby ends, Josh finds himself in hot water. Someone is playing practical jokes on the other players, and the coach is sure it's him. Andy swears his dad is innocent. Who would want to frame Josh? And why?
