Factual error: Throughout the move, when teams are taking batting practice (the pitcher has a screen in front of him), the batters are wearing helmets. MLB players don't wear batting helmets during batting practice. They often wear their regular cap backwards or no cap at all, but they don't wear helmets because the pitcher is simply giving them strikes to swing at, no brush-back pitches or chin music.

Continuity mistake: Near the end after winning the AL championship, Vaughn vaults the wall to chase down the teacher. As he climbs the wall, you can see a fan reach out and grab his elbow to help him up. The shot changes to a front view of Vaughn coming over the wall and the fan is now too far away to reach him with no time in between shots.
Rube Baker: Mr. Parkman, you're a great ballplayer and I just like to say, your standing on the tracks and the train's coming through, butthead.
Trivia: The line the biker chick says in the beginning, "Say it ain't so, Rick" (after being disappointed in Wild Thing's clean cut look and using the word, cute), is from the legend of a kid saying "Say it ain't so, Joe" to Shoeless Joe Jackson when the White Sox were accused of throwing the World Series. Joe Jackson also played for the Indians before the White Sox.
