Corrected entry: In the scene where Cerrano goes into the outfield to assist the bird he hit, he's tagged out by an infielder. The reality is that he was out the second he ran out of the baselines. Rule 7.08 of Major League Baseball: Any runner is out when: (a) (1) He runs more than three feet away from a direct line between bases to avoid being tagged unless his action is to avoid interference with a fielder fielding a batted ball; or (2) after touching first base, he leaves the baseline, obviously abandoning his effort to touch the next base.
Correction: That's not how the basepath rule is interpreted. The rule establishes the baseline as the path between the runner on whom the defense is attempting to make a play, and the next base. Until the other team begins to make a play on Cerrano, he can run to wherever he wants. So his basepath in this case would be from where he picks up the bird in the outfield to second base - it's 3 feet around THAT line he can't leave. So the outfielder tagging him is correct in terms of the timing of the run.
As a side note, though, the fact that the outfielder just puts the ball in Cerrano's hand as the tag could have been a problem, since it could be argued he didn't hold onto the ball after the tag and thus Cerrano wouldn't be out yet. But in this case maybe the umpires ruled the ball was dropped in the transfer (i.e. the fielder demonstrated enough control of the ball through the tag to establish the out).
Corrected entry: All ownership changes in Major League Baseball would have to be approved by the other owners in the league. To gain the approval of the other owners, Dorn would have to show a financial ability to keep the team solvent, which he cannot do. Even if he gets past this hurdle and gets the other owners to approve him, there is almost no chance the owners would approve Rachel Phelps' move to buy back the team, especially after her attempts to lose in the first film.
Correction: If the choice is between someone they dislike owning the team and the team devolving into bankruptcy or foreclosure, they could easily approve to avoid the bad press and complications. Also, it is not a legitimate mistake to argue what someone would or would not have done.
If the league doesn't like any of the prospective owners, they can assume league ownership of the team until an acceptable buyer comes along.
Corrected entry: Throughout the entire movie, Parkmans' helmets never have a protective piece covering the ear. Any baseball games at any level the helmets have that protective piece over the ear.
Correction: This is USUALLY true but not entirely, especially in the 80's. I remember several of my favorite players, including then Chicago Cub's catcher Jody Davis, wore the same kind of helmet and I used to wonder that myself. Rare yes, but not unheard of.
John Olrud wore that same helmet as well when he played in late 80's, early 90's.
John Olerud wore a helmet without earflaps in the field. He batted with a helmet that had earflaps.
Correction: MLB made it mandatory for batting helmets to have at least one earflap in 1983. Players who were already using non-earflapped batting helmets up until that point had a grandfather clause, so they could keep wearing those if they wanted to. I guess we have to assume Parkman has been playing since before 1983.
Correction: All the umpire said was that the runner didn't make it home before he was out. An umpire never called him out when he tagged him. The outfielder who caught the ball didn't even tag him, he handed him the ball and said, "I'm sorry, but you're out Mr. Ghandi." The line Doyle said about being tagged out administering CPR to the bird was just his character's attempt at humor.
