The misfit kiddie baseball team from the first film is given the opportunity to play in a Junior League match between double-header games at the Houston Astrodome. Two obstacles stand in their way: beloved teammate Timmy Lupus (Quinn Smith) has broken his leg, and the team has no adult coach. Attempting to change their luck, star player Kelly Leak (Jackie Earle Haley) tries to talk his estranged dad (William Devane) into coaching and locates a self-proclaimed hotshot pitcher named Carmen Ronzonni (Jimmy Baio). Watch for quickie cameos by real-life Houston Astros members Robert J. Watson, Enos Cabell, Roger Metzger, James Richard, Joe Ferguson, Ken Forsch, William Virdon, and Cesar Cedeno.
