Baker's inability to throw the ball back to the pitcher was based on former New York Mets catcher Mackey Sasser. Sasser was very successful at throwing out runners attempting to steal second, but had a mental block causing him to flinch several times when trying to throw the ball back to the pitcher. Many baserunners took advantage of this affliction and stole bases while he was triple pumping his throw, and/or lollipopping the throwback.

While Camden Yards doubled as Cleveland Municipal Stadium, scenes depicting Indians road games were filmed mostly at nearby Baltimore Memorial Stadium.

The character Isuro Tanaka was something of an anomaly of that time. At the time of the film's release, there were no Japanese players in the Major Leagues, and only one Japanese player had ever played (briefly) for a ML team. The influx of Japanese players in US Major League baseball didn't begin until a few years after the film's release.

Wesley Snipes wasn't able to reprise his role of Willie Mays Hayes, and was replaced with Omar Epps.

Kevin Hickey, who plays Indians pitcher Schoup, made his major League debut in 1981 as a pitcher for the Chicago White Sox, the very team the fictional pitcher Schoup plays against in the film.

Continuity

When Willy Mays-Hayes yells to distract a player and cause him to drop a fly ball, the freeze-frame newspaper shot of that moment appears with the headline "Tribe gives Jays the Willys." However, the player who dropped the ball is clearly wearing a Baltimore Orioles uniform, not a Toronto Blue Jays one.

In the top of the 9th of game 7 of the ALCS, it is mentioned that Chicago's Beck already had a 2 run double in the game, presumably the hit that drove in Parkman when he ran over Baker at the plate (which is the only run scoring play the Sox had other than the 3 run HR Parkman hit later). This should not have been possible, since Parkman hit behind Beck in the 9th, so Parkman could not have been on base when Beck doubled.

In the last game against Chicago, Willie is batting and we hear Harry Doyle say over the radio, "Willie Mays Hayes is trying to pick up Miller from third." But if you look at third base, there is no player there.

During Vaughn's commercial shoot, they announce take 87. However the clapper board clearly says take 83.

The three fans (Randy Quaid and friends) looking to catch Willie Mays Hayes' homeruns on opening day disappear and reappear between shots of the left-field wall.



Factual errors

When Tanaka climbs the left field fence and makes the division-winning catch, the catch should not have counted. As per MLB rules, when Tanaka establishes a stationery position out of the playing field (as compared to falling or jumping), the play should have been ruled a home run.

In game 7 of the ALCS, there are runners on first and second. The runner on first is held on, but in an actual game, the first baseman would never hold on a runner with a guy on second.

In the second game of the doubleheader versus the Red Sox, when Willy comes in to pinch run, another unknown player comes up to bat. While Willy steals 2nd, 3rd, and home two pitches are thrown to the batter. Then Cerrano goes in to pinch hit but a pinch hitter cannot go in in the middle of an at bat unless the player is injured.

Major League 1 takes place in 1989. The story line for part 2 takes place one year later (1990). That same year Rick Vaughn is on the Tonight Show with Jay Leno but Leno didn't start hosting the show until 1992.

In the bottom on the ninth with the bases loaded the catcher, Rube, signals for the fast ball by holding down one finger. With a runner on second base the catcher would flash multiple signs so the runner couldn't signal the batter what was coming.



Incorrectly regarded as goofs

At the time of the movie, The Indians held spring training in Winter Haven, Fl enabling them to play the Red Sox (as well as Mets, Twins and Blue Jays) in exhibition games.

During a game with the Orioles, Hayes hits a pop fly to the second baseman and yells, "I got it!" to distract the fielder so that the ball will drop and he can be safe at second. However, his call is a form of interference and Hayes should be out according to MLB rules. However, Alex Rodriguez of the New York Yankees did the similar thing in 2007 against the Toronto Blue Jays and was not called out.

After Cerrano's fly ball hits the bird he runs out to center field to pick up the bird, and is tagged out by the center fielder. As soon as Cerano ran out to center field he would have been called out for abandoning his effort to reach the next base and did not need to be tagged out.

When the Indians are playing a spring training game against the Red Sox, they are playing in Arizona. This couldn't happen. The Cleveland Indians play all their spring training games in the Cactus League in Arizona, while the Boston Red Sox play all their games in the Grapefruit League in Florida. From 1993 to 2008, the Indians did Spring Training in Winter Haven, Florida. That means they would be in the Grapefruit League during the time of the movie, so them playing ST games with the Red Sox as well as the Blue Jays and the Mets (as depicted in the movie) would be correct.

On opening day, the White Sox score their first run with three consecutive singles starting with the top of the order in the third inning. Given that Vaughn had a 1-2-3 inning to start the game, how did the White Sox start the third inning with the top of their order, without scoring a run in the second inning? The White Sox first three hitters made outs in the first inning. It is possible to send six hitters to the plate in the second inning in order to start the third inning with the number one hitter without scoring a run. For example, three walks and three strikeouts.



Revealing mistakes

When Jack Parkman hits a home run off of Rick Vaughn, the ball flight is clearly New Comiskey Park, even though none of the movie was filmed there. Also, the scoreboard with the batter's name on it is visible. It clearly says DEAN P is the first name and the first initial of the last name. The team on the opponent line says RANGERS, so that video was taken from a real game where 3B Dean Palmer of the Rangers hit a home run.

When Rick Vaughn visits the kids (all of whom are supposed to be Indians fans) and takes them autographed baseballs, a Chicago White Sox jersey is briefly visible under the jacket of one of the kids.

When the newspaper headlines come on screen after the Indians regain first place, the headline to the right says that they can "cinch" the division when it should have read "clinch."

In the dugout fight, Willy braces himself just before Rick attacks from behind.

Manager puts Roger Dorn in to pinch hit in the 7th game against the White Sox pitcher who always pitches him "inside". He is told to let the pitcher hit him because we need another runner on base. He does so but the ball obviously hits him on the upper left arm. The announcer states he was hit in the back and Dorn is rubbing his back as he goes to first base.



Miscellaneous

Parkman is supposed to be a stuck up, arrogant player and when he hits a home run during the Opening Day game, he refuses to give his Indians teammates a high five for hitting the home run. But yet, in Game 7 of the ALCS he gives his White Sox teammates a high five.



Audio/visual unsynchronized

During the last game, announcer Harry Doyle says that the runners will be moving with two outs. However, when Shoop pitches the ball, the runner on second base never moves.

When Rick returns as the "Wild Thing", his music clearly starts playing before the girl at the desk starts the tape.

When Vaughn is talking to Nikki in the pizza shop, we hear the sound of Vaughn putting his glass down before it hits the table.



Errors in geography

Set in Cleveland, yet obviously filmed in Baltimore. Oriole Park at Camden Yards, home of the Baltimore Orioles, is used as the Indians' home park, even though it looks nothing like Cleveland Municipal Stadium. Advertisements for Baltimore businesses like "Sheraton Inner Harbor" and the Baltimore Sun are seen as well as a few Baltimore landmarks.



Plot holes

Phelps buys enough of the team from Roger to keep them financially stable. However, since her plot to move the team to Miami was discovered by the team (and apparently the press), she would have been guilty of collusion and forbidden by other MLB owners from having even partial ownership of any team.

Jake Taylor becomes a coach when Cleveland keeps Parkman and Baker as the two catchers. However when Parkman's rights are sold to Chicago, a second catcher is never added to the roster, and Baker seems to be the only one on the roster. It would have been sensible to have Taylor become Baker's back-up.



Character error

Dorn's accountant uses incorrect financial vocabulary when advising Dorn he is going broke. Dorn needs to increase his revenue to keep the team afloat, not his profits.
