Plot hole: In the game against Fayetteville, Crash puts down two fingers indicating he wants Nuke to throw the curve. When the camera then shows Nuke shaking him off, you can see Fayetteville has a runner on 2nd. Even in the minors the catcher will mix up the signs so the runner on 2nd couldn't steal them and tip the pitch. He'd never just hold down two fingers.

Directed by: Ron Shelton
Starring: Susan Sarandon, Kevin Costner, Tim Robbins, Trey Wilson
Continuity mistake: In a bus scene Crash is shown holding a guitar talking about being in the majors. In one scene he's just holding the guitar, the next he has a pair of sunglasses in his hand while holding the guitar. The next scene the sunglasses are gone. A couple of shots later the guitar is sitting in the seat next to him. When Laloosh challenges Crash to a fight, he's holding the guitar again.

Trivia: When the film was shown during the 2003 Baseball Hall of Fame ceremony, Susan Sarandon and her partner Tim Robbins were not invited because of the controversy surrounding their anti-war views on Iraq.
