When the Springfield Nuclear Power Plant softball team proves to be pretty decent with Homer as the star player, Homer makes a bet with the Shelbyville Nuclear Power Plant owner.  In order to guarantee a victory, Mr. Burns hires nine professional athletes as ringers: Wade Boggs, José Canseco, Roger Clemens, Ken Griffey, Jr., Don Mattingly, Steve Sax, Mike Scioscia, Ozzie Smith, Terry Cashman and Darryl Strawberry.  However, as one-by-one they fall victim to misfortunes, the original Springfield team goes up against Shelby and wins.
