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.
Other mistake: During the one game playoff against the Yankees, the runner Taylor picks off at first base has the same number as the batter who had just struck out. Also, the number they both wear has been long since retired by the Yankees and therefore no player could ever wear it again. Again, in the first game against the Yankees, the first base coach also has the same number, making it three Yankee players with the number 37.
Visible crew/equipment: During the first game of the season, The camera pans across the press box to reveal Harry Doyle for the first time. During the pan, the reflection of the camera can be seen in the glass.
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.
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.
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.
Continuity mistake: At the end, when they are celebrating, Wesley Snipes jumps into a player's arms. his helmet is on then knocked off but back on again in the next shot.
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.
Revealing mistake: In the celebration scene at the end, there are multiple times when you see huge sections of the stadium with no people in them. The most obvious is when WMH jumps into Jake's arms.
Deliberate mistake: When he bats, Jake uses a helmet with no earflap. In 1983, it was instituted that players must wear a helmet with at least one flap; however, it's possible that Jake is exempt from this rule under Major League Baseball's "grandfather clause," which allows any player who played before 1983 to continue using the flapless helmet.
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.
Continuity mistake: In the morning after Charlie Sheen's character beds Dorn's wife, his necklace keeps moving around his chest. One minute its dangling off to the right, the next it's carefully centred on his chest, and in one shot it disappears completely.
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.
Other mistake: Roger says to Jake that he's going to be a free agent next year, which he's excited about and why he doesn't want to risk injury, but then when he learns of the owner's plan and that he'll be given his release next year, which is the same as free agency, he's upset. Plus you can't be given your release when your contract ends, which it must be if he thought he was going to be a free agent.
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: 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.
Continuity mistake: When Lou Brown and the pitching coach are working with Vaughn, walk over to the plate and stand on either side of Taylor (to simulate a batter on either side). In the first shot, you can see a "No Pepper Games" sign off to the left side, the shot cuts to Vaughn, and then back to the coaches and Taylor. All of a sudden, the sign has moved from over on the left side on the backstop, to directly above Taylor on the backstop and Vaughn proceeds to smash it with a high fastball. Another mistake entry said this: 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. The coaches didn't move, the sign did. There's only one home plate there. How could the plate move? It had to be the sign.
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.
Continuity mistake: In the top of the ninth, as Harris struggles with his control a shot of the scoreboard shows both teams have 2 runs, 7 hits and no errors. Harris then walks the next batter to load the bases, and Vaughn is brought in to face Heywood, whom he strikes out. Thus the Yankees should still have 7 hits heading into the bottom of the ninth. Yet when the scoreboard is shown as the Duke comes in shows the Yankees with 9 hits. This means they somehow picked up 2 hits in between the half-inning, which is impossible. The only way to gain hits like that is if the scorekeeper changed two errors from earlier in the game into hits, but the scoreboard indicated there no errors were ever made in the game.
