Deliberate mistake: During the Hall of Fame sequence at the end, Dottie sees the display about Jimmie hitting 58 home runs and there is a long wide shot of it as she stands next to it. Then there is a close-up of the bottom of the text which says born 1906 - died 1987, which wasn't present during the wide shot a moment earlier. The filmmakers likely saved this for the close-up for dramatic effect, but by blocking the initial shot without that part obscured it makes the text magically appear out of nowhere.
A League Of Their Own (1992)
1 deliberate mistake - chronological order
Directed by: Penny Marshall
Starring: Tom Hanks, Bill Pullman, Jon Lovitz, Geena Davis, Madonna, Lori Petty, Rosie O'Donnell
Visible crew/equipment: After the Peaches are introduced at their first game, they run onto the field. If you watch the background carefully, Rosie O'Donnell clearly trips over a production wire. (00:35:50)
Trivia: The notoriously hard-to-work-with Debra Winger was originally cast as Dottie, but she and Penny Marshall had so many creative differences that she was replaced by Geena Davis.
Answer: An unnamed pitcher. I believe it was the character played by Janet Jones and listed as "Racine Pitcher"
