Continuity mistake: During the tryout/league formation sequence at Harvey (Wrigley) Field, every shot takes place at the famous stadium, except one. When Betty Spaghetti backpedals to catch a fly ball, the background shows a rickety wooden outfield fence, not Wrigley's famous ivy-covered walls. (00:25:20)
Continuity mistake: During the scene where Dottie and Jimmy are sitting beside each other at the front of the bus having a conversation, the camera cuts to Mae painting Kit's nails on the back seat of the bus. When the camera cuts back to Dottie and Jimmy, if you look at the back seat of the bus, Mae is sitting by herself and Kit is already about to sit back down in her seat in the middle of the bus. It doesn't seem likely that there would have been enough time for her to be in that position so quickly. (01:11:45)
Continuity mistake: A very early 1943 scene in Oregon shows baseball scout Jon Lovitz waiting in the club car of a train with a steam engine complete with smokestack. Geena Davis and Lori Petty run to catch the train for tryouts. But after they board in the next scene, the steam locomotive has disappeared and now a modern diesel engine is in front of the train heading east to Fort Collins, Colorado. (00:14:45 - 00:16:05)
Continuity mistake: Kit, still in her uniform, encounters Dottie on Dottie's way out of the Peaches locker room after the final game. After being sweaty and dirty during the game, somehow Kit's uniform is now spotless and her hair looks likes it's been washed and blow dried.
Continuity mistake: When the Peaches are outside the bus talking after it stops, watch the white horse in the background behind Dottie. It changes position more than once. (00:43:00)
Continuity mistake: When the girls are relaxing at Suds Bucket, Ellen Sue is on the dance floor, then seated with her partner and back onto the floor again all within a matter of shots. (00:45:40)
Continuity mistake: After the final game we see the girls leaving the changing room, but Dotty is still there. The last two girls are about to leave, and we see Dotty about to put her tights on. She has not started putting them on, but then the shot changes and she is already rolling them up her legs.
Continuity mistake: When Dottie and Jimmy are arguing whether Marla should bunt or swing away, while Jimmy is reading the paper the Rockford Peach emblem on his uniform switches from solid peach to red/white then back to solid peach. (00:51:40)
Continuity mistake: During the music clip, when Jimmy is finally starting to take over the managerial duties of the team, there is a scene where he is instructing Beverly before batting. We see the very same spectators sitting behind the Rockford bench, who were there in the other scene where Jimmy and Dottie were concurrently instructing Marla before batting - which happened several games before.
Continuity mistake: The first teams had 15 players on them, not 16. (00:22:45)
Continuity mistake: When Jimmy meets Dottie and Bob after the final game, we first see all three of them, with Jimmy and Bob shaking hands. While they are still shaking hands, the camera switches to Jimmy's head and upper body, and he is visibly not doing a handshake - instead within a second he is shown giving his hand again to Bob for a second handshake. Then, while he is still shown doing the second handshake, the camera switches to Dottie's and Bob's heads and upper bodies, with Bob visibly not doing a handshake. Finally the camera switches back to showing all three persons, with Jimmy just pulling back his hand from a handshake.
Continuity mistake: When the selected team members are announced, we see Mae and Doris hugging each other in rejoice. About one second later Kit is shown rushing through the crowd, and we now see Mae and Doris standing about two meters apart from each other, both facing towards the notice board, with a couple of other girls standing between them.
Continuity mistake: During the championship game Kit is pitching for Racine and her sister Dottie hits a line drive that almost "takes her head off". Later when Kit goes to the dugout, a closeup shot shows her sitting with a jacket on her right arm crying and freaking out because Dottie got the best of her once again. But in the next shot, Dottie comes walking out behind the plate to catch, looks over at Kit who is still crying in the dugout, and the jacket is no longer on Kit's arm as it was just a second before.
Continuity mistake: When Dottie and Jimmy argue about whether Marla should bunt or swing, Doris is cleaning a chocolate bar from her cleats. The first shot shows the entire heel covered, and she is cleaning it off. The next shot shows the heel is clean. Then the next shot is back to the entire heel being covered with Doris trying to clean the chocolate off.
Continuity mistake: When Jimmy is shouting at the team members to get on the bus, we first see Evelyn and Doris in the background while they are descending the stairs of the hotel entrance and hurrying on the pathway towards the vehicle. Then the camera angle changes, and we now see them from a close distance descending the stairs again.
Continuity mistake: In the movie Ellen Sue (she played short stop and was a pitcher) was #1. You can see it on her uniform throughout the movie. At the very end when they are showing credits it shows pictures of the girls playing ball. On the back of Ellen Sue's uniform is shown #2. (00:35:50 - 01:59:25)
