Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Other mistake: When they do the SPECIAL play, and the pitcher throws the ball to the first baseman, and the first baseman looks for the ball along with the guard and 2 to 3 players. The ball is really at 2nd base, a trick play, but there is NO base coach.
Other mistake: In the scene, they show the newspaper headline "Tribe Gives Jays the Willies." At the bottom, it says "Braves Lose to Mets," when in the previous scene, the scoreboard in the background says the Braves play the Rockies, not the Mets. Also, the Indians were playing the Baltimore Orioles, not the Blue Jays.
Other mistake: In the championship game at the end, Ray Mitchell hits a two run homer to tie the game. As Mitchell is crossing home, he never touches the plate.
