Continuity mistake: The batting order in the one-game playoff is Taylor-Dorn-Cerrano (as seen in the 7th), with Hayes batting before Taylor (as seen in the 9th). Cerrano hits the homer with two outs in the 7th, and Hayes is shown batting with nobody on, and two outs in the 9th. If they faced the minimum, Hayes would've been up with only one out (#5 batter gets the third out in the 7th, 6-7-8 batters get out in the 8th, and the #9 batter gets one out before Hayes). There's no way they could've gone through the line-up again without scoring a run. The furthest they could've gotten was the #8 batter (two spots before the leadoff Hayes) coming to bat in the 9th with two outs and nobody on. (01:23:30)
Continuity mistake: After the Indians win the pennant, they show a shot of the crowd where Jake's girlfriend is. In the first shot there's a guy running down the stairs. The next time they show the stands he's running down again. (01:40:15)
Continuity mistake: When Taylor is giving signs to Wild Thing while pitching to Clue Haywood in the one game playoff, he has a smudge of dirt on his pants from sliding. You can see it in the closeup shots of his signals on his left hamstring. When the view backs out, his uniform is completely white. (01:30:50)
Continuity mistake: In his first pitching outing, Charlie Sheen is at the mound and the stadium clock can easily be seen in the background displaying twenty minutes to eleven. Now take into consideration that it is late in the ball game and it is a day game, this is not possible unless the game was started at nine o'clock or so. That's not even done on the west coast. The clock remains at 10:40 during various scenes of the film. (00:38:15)
Continuity mistake: In the playoff game with the Yankees, the last out of the top of the first inning is recorded when Dorn throws out a runner on a ground ball. The first baseman in the scene is right-handed. Yet when they show a shot of the team coming off the field, the first baseman is left-handed. (01:21:20)
Continuity mistake: In the last scene of the movie, when they all gather for the still shot, all the players have clean uniforms. When they all were shown moments before, all were dirty, especially Willie Hayes. (01:40:50)
Continuity mistake: Jake Taylor follows Rene Russo home the second time, and then is seen surprising her in her own apartment at the top of the stairs. Later, he returns again inside the apartment, only to see Rene had probably moved in with Tom. How did Jake get in these two times? It is safe to say that he would have no reason to have a key to the place. (01:03:00 - 01:16:30)
Continuity mistake: In the scene where Jake shows up at the apartment and there is a dinner party gong on, he is sitting and a tray of appetizers is passed around. The husband of the lady in the purple dress offers her the tray and she waves it off and he holds on to it. In the next scene, she is offering an appetizer to Jake. (00:48:25)
Continuity mistake: When Vaughn enters the playoff game, the scoreboard introduces him with a glittery "Wild Thing" display, then reverts to showing the score by the end of his warm-ups. However, when Dorn talks to him on the mound prior to Vaughn's first pitch, the board again shows the glittery display. (01:29:40)
Continuity mistake: During the opening day game, the angle of the shadows changes drastically between shots. (00:21:20)
Continuity mistake: During the final game, the announcer says that Harris is "working on a seven hitter." He then gives up a double, but multiple shots of the scoreboard after that show the Yankees still with only 7 hits. (01:26:35 - 01:27:24)
Continuity mistake: In spring training, Lou Brown and the other coach walk over to check out Charlie Sheen's pitching. When Lou says "all right, let's see what you can do," the coaches are pretty much either side of a post supporting the fence, with a "no pepper" sign to their right. When Sheen pitches, the two coaches have suddenly moved about 6 feet over, away from the post, with the no pepper sign directly between them. (00:15:15)
Continuity mistake: With Vaughn pitching in game 121 (current record 60-60), he gives up a walk and then a double (according to Harry Doyle). Then he gives up the three-run homerun to Heywood - runners are shown running from first and third, and the guy from first is in a full sprint, which wouldn't happen on the shot that Heywood hit.
Continuity mistake: During the scene where Harry Doyle announces that Ricky Vaughn is one out away from his first major league victory and Vaughn is about to pitch to the A's Mike Rexman, watch as catcher Jake Taylor leaves homeplate and comes up to give Ricky some pitching advice. There are only a handful of people in the stands behind home plate (roughly 20). However, not even 30 seconds later when Taylor walks back to the plate and Mike Rexman stands in to bat, the area behind home plate is now FULL of fans, probably 100 or more. (00:54:35)
Continuity mistake: In the scene where Willie Mays Hays is stealing home in the final game, the first baseman throws to the catcher. The catcher catches it - with his shin and left foot lying directly across home plate. It switches to an overhead shot, and the catcher is a good five or six feet away from the plate.
Continuity mistake: At the end of the movie when the Indians are playing the Yankees, in the 9th inning Hays is on 2nd and starts to steal 3rd. Taylor bunts the ball and the 3rd baseman and shortstop are shown in the camera view, but Hays is nowhere to be seen. He should have been in the camera shot as he had not reached 3rd base yet.
Continuity mistake: In the playoff game against the Yankees, right after Uecker announces Harris (the pitcher) is in trouble, there is a shot of him from behind the mound. It's a little out of focus, but look at his hair from under his cap. It doesn't match his hair in the next shot where you see him throwing a pitch. (01:22:35)
