Zack Waddell's baseball IQ makes him one of the Roadrunners' most important players. When a new kid, Dustin, immediately takes their catcher's spot, Zack is puzzled. Dustin doesn't have the skills to be a starter. So Zack offers to help him with his swing in Dustin's swanky personal batting cages.

Zack accidentally overhears a conversation and figures out why Dustin is starting—and why the team is suddenly able to afford an expensive trip to a New York tournament. Will Zack's baseball instincts transfer off the field? Will the Roadrunners be able to stay focused when their team chemistry faces its greatest challenge yet?
