Corrected entry: Toward the end of the movie when Tyler is playing the final baseball game and he gets his big hit, the pitched ball hits the ground just before it is hit. In baseball the ball would have been considered dead and the home-run would not have counted.

Correction: It's a kids' league though with changed rules (every kid gets to play) so there is probably some slack when it comes to pitching.
