Major League Mess-Up — Nancy Krulik

It's baseball season, and Katie and her friends are busy rooting for their favorite team, the Cherrydale Porcupines. Katie loves the team, but can't understand why her friends are so obsessed with the team's star shortstop, Mike Reed; she prefers the old shortstop who now sits on the bench every game. But when Katie is switcherooed into the team's star shortstop, she learns that she should never judge someone until she's standing in their size-12 baseball cleats!
