Continuity mistake: The point is made a couple of times in the movie that Bobby Rayburn is playing centerfield for the Giants and moving Juan Primo to LEFT field. But on Opening Day, when Rayburn and Primo collide in the outfield trying to catch a fly ball, Rayburn's moving to his left while Primo's moving to his right, indicating that Primo was playing RIGHT field.
Continuity mistake: In the final scenes when Snipes has to hit a home run to save his son, the pitcher is addressed as Martinez, but as he throws the last ball you can just see the back of his jersey where it shows the beginning of his name, but instead of starting with a M it starts with a C.
Plot hole: In the scene after Gil saves Bobby's son Shawn, Gil claims he doesn't know who Bobby is. Even guessing that he may be Barry Bonds. Then in the next scene when Gil is pitching to Bobby he knows all about his slump, number, contact, and about Primo's death and this did not strike him as odd?
