Its baseball season, and Katie and her friends are busy rooting for their favorite team, the Cherrydale Porcupines. Katie loves the team, but cant understand why her friends are so obsessed with the teams star shortstop, Mike Reed; she prefers the old shortstop who now sits on the bench every game. But when Katie is switcherooed into the teams star shortstop, she learns that she should never judge someone until shes standing in their size-12 baseball cleats!
