When "Downtown" Anderson is shown batting for the Minnesota
Twins and he strikes out, he is wearing number 14. But when he returns to the dugout and is chastised by Carlos Liston, Anderson is wearing number 16.
During the final game against the twins at buzz stadium the score board says the buzz got 2 runs in the 7th inning then 1 run in the 8th inning and it should be 4-3 yet they are only credited with 2 runs making the score 4-2 yet when number 40 hits and the player from 3rd scores they are not credited with the run but are finally credited with the run from the 8th inning so now the score is 4-3 even though with the player scoring from 3rd it should be 4-4.
In Major league II, Roger Dorn is forced to sell the Indians back to Rachel Phelps because he has run out of money to keep the team afloat. However, it is never explained how he has the money to buy and run the Twins.
There are two obvious instances of blue screen use. One is when Taka Tanaka is making a relay throw home during the game in Minnesota. Another is when a Buzz player is sliding home beneath an apposing catcher. It's an obvious lift of a similar scene in one of the prior Major League movies in which the catcher appears to be added into the shot.
At 37:02 after Dorn gets off of the phone with Gus there is a shot of the seats and in the middle row there is a person wearing a yellow shirt and ten minutes later at 47:01 when the buzz are in the stadium they show fans getting to their seats and they use the same scene as before. Note the person in the yellow shirt in the middle of the screen.
A batter lays down a bunt and Gus (the catcher) is shown stepping forward and picking up the ball. The ball is stationary and sitting just a few feet in front of home plate, which is inconsistent with the speed of the ball that was hit. Obviously, a second baseball has been placed on the ground (initially out of the camera's view) for Gus to field.
