Revealing: At the end of the decisive game, the bad guy hits a deep foul ball. During that hit, they show the ball against a black background. If you look very closely at the bottom of the screen, you can see a hand throwing the ball.

Factual error: For a baseball movie, you would think they would have known the rules of the game better. There is a scene in which Henry uses the "hidden ball trick" to pick a runner off of first base. He stands on the rubber on the mound with only the rosin bag in his hand while the first basemen holds the ball. It is a violation for him to stand on the rubber without the ball in his hand and is called a "balk". Technically the runner should have been awarded second base.

Other: When Chet Steadman blows out his arm, Sal Martinella tells him that he's going to save Chet for the playoffs. But since the Cubs are currently playing the NLDS, they're already in the playoffs. [Note: "The playoffs" is defined as everything played after the regular season ends, which includes the Division Series.]

Continuity: In the final match of the season, the time shown on the scoreboard clock remains the same throughout.

Continuity: In the big game the Cubs' manager says to Chet, "You gave me six great innings." But somehow, Henry pitches four innings when there are no extra innings in the game. How unusual.

Continuity: When one of the batters is hit, watch closely and the ball is tossed from above.

Continuity: When Henry, his mom and Chet are in the airport, the scene shows Henry and Chet just coming out of the gate and they have no bags in their hands. They start running away from the media with Henry's mom across the skywalk, then it shows them exiting the airport still running. Both Chet and Henry have bags in their hands.

Factual error: In the NLDS against the Mets, before he enters the game, Henry is sitting with the rest of the team in the dugout. As a relief pitcher, he should have been in the bullpen with the other relievers.

Visible crew/equipment: When Henry's mom punches Jack, watch as he rolls down the steps: it is not Jack but a stunt double.

Factual error: At the first Cubs home game of the season, you can see that the ivy on the back wall of Wrigley Field is green. The ivy is never green like that during the first two months, at least, of the season.

Continuity: At the end, in the big game, they show Henry striking out people as usual after replacing Chet Steadman. During the time when they show one strike after another, for a few seconds, you can clearly see that Chet Steadman is back on the mound.

Factual error: During one of the games, a batter swings and makes contact. In the next shot (of the Chicago pitcher), the second-base umpire can be seen in the background making the "home run" signal (finger pointed upwards, moving in a circular motion). The next shot, from above, shows the ball bouncing into the outfield for a single. We all hear about how the umpires should get glasses, but first, this one should get a nice ol' pair of eyes...

Continuity: In the scene where Henry, his mom and friends are going down the escalator from getting Henry's cast off, Henry's Mom is on one side and the boys are on the other. The side that Henry's Mom is on is going down, but the side that the Boy's are on is going up. They are all standing still for a minute, but they stay side by side while one escalator is going up and the other is going down.

Continuity: When Henry gets his cast put on, there is a brace going from his upper arm to his waist that is molded in place with the cast. After he leaves the doctor's office, it has suddenly disappeared.

Factual error: At the end of the season the Cubs end the year tied with the Mets for the Division. This is correct since the MLB didn't switch to 3 divisions until '94 (when there were no playoffs that year due to the player strike). In the 1 game playoff with the Mets John Candy gets excited and declares the winner will go to the World Series. After the game the Coach tells Chet "I'm saving you for the playoffs". If Candy was right about the game then the coach is a complete idiot for not knowing that they are already IN the playoffs. Now they couldn't have been playing in the Division Series (the 5 game first round series) because that didn't exist until '95(would have started in '94 if not for the strike). So either the game was meant to be game 7 of the LCS (League Championship Series), which isn't possible because at the time the Cubs and Mets were in the same division and before '95 (once again due to the strike) 2 teams from the same division couldn't make the playoffs together, or this was a one game playoff to decide the division winner and then the winner would go on to the LCS, which makes Candy wrong. Either way this isn't explained very well at all and confuses many.
