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: 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. (00:15:15)
Continuity mistake: In the scene where Pedro is explaining how Jobu will help him "take fear from bats", he sticks a cigarette in Jobu's mouth and lights it. Then when he turns around to speak to Eddie in the next shot, the cigarette has been replaced by a cigar. (00:18:25)
Continuity mistake: During the opening day game, the angle of the shadows changes drastically between shots. (00:21:20)
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 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: 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: 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 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. (01:17:40)
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 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)
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: In the playoff game against the Yankees, Roger Dorn (#24) hits a single. We then see a wide shot of the runner rounding first base wearing #8. The closeup shot then shows Dorn in his #24 jersey. (01:23:46)
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 the top of the ninth, Harris is working on a 7 hitter and gives up a double, but the inning ends after a walk and strikeout. Thus the Yankees should have 8 hits heading into the bottom of the 9th. Yet the scoreboard when Duke comes in shows the Yankees with 9 hits. This means they picked up a hit in between the half-inning, which is impossible. And the scorekeeper couldn't have changed an error from earlier in the game to a hit because the scoreboard never listed an error had been made. (01:27:20 - 01:33:30)
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: 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: 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. (01:39:05)
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: 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)
Answer: He just shows up, uninvited. When he arrives, they can't find his name on the list; he's later (comedically) removed from camp in the middle of the night when security carries him out on his bed (while commenting, "This is the guy who wasn't invited to camp"). So, he's relying on his speed and charm to get him a spot on the team... which, of course, ultimately works.
