None of the boys playing for the South Park Cows, the town's Little League Baseball team, enjoy the sport at all.
The Cows end up winning again and again against opponents whose efforts at throwing games are more successful, and they reach the state championship against Denver.
While training to be the best fighter he can be, Randy becomes terrified when he meets the Denver Little League team's "Bat Dad", who wears a purple Batman cowl and cape, and who is both heavier and more misbehaved than he is.
Just as the Cows find themselves on the verge of winning, Randy appears in the stands and provokes a fight with the Bat Dad that spills onto the field; the officials warn the two men that the next one who acts aggressively will get his team disqualified.
Though Randy gets knocked down, the boys' cheering, combined with a hallucination of a crowd including Mickey Goldmill and Sharon (who had previously stated he could simply choose not to fight if he didn't want to) cheering him on, inspires him to stand up and continue fighting before finally knocking out Bat Dad, resulting in the Cows' disqualification and Denver's victory by default.
The episode's idea originally came from series co-creators Trey Parker and Matt Stone thinking that the children of South Park would look cute in baseball uniforms.
The choice to go ahead with a baseball-themed episode did create some problems animation-wise, however, as most of the children look nearly identical wearing the same uniforms.
