Continuity mistake: When the Owls are playing for their district championship, the other team's best batter comes up in the last inning. As he is walking to the plate, he is wearing Nike shoes, but when he digs into the batter's box, his shoes are Reebok.
Continuity mistake: When Jim Morris is at the tryouts pitching, and he is on the pitcher's mound, you can clearly see that he has sweat on the neck of his shirt and on the armpits of the shirt. However when he goes to throw out the diaper, the sweat is gone.
Continuity mistake: In the same when Jim pitches at the training camp, before he starts, the sky is bright and clear. When he starts pitching the sky starts to get darker and cloudier but when he finishes pitching the sky is bright once again. How can the sky change that fast?
Continuity mistake: During the sixth inning of the game between the Devil Rays and the Rangers, a Texas player who has just gotten a hit runs in the wrong direction, toward third base.
Continuity mistake: At the tryouts Jim was changing his baby's diaper and when he pulls her off the hood of the trunk to pitch, he drops a blanket on the ground. In the next shot the blanket is gone, but he didn't pick it up, neither did Hunter, because he is still sitting on the truck and has not appeared to move. What happened to the blanket?
Continuity mistake: In the scene where Dennis Quaid tries out for the majors, he finishes his pitching and his grey shirt is noticeably covered with sweat stains. Moments later after leaving the field, as he approaches one of the scouts, all the sweat stains are gone and his shirt is completely clean.
Continuity mistake: Just as Jim is called in to pitch, he is slowly trotting through the field. In the background, there is a large Southwest airlines billboard. If you pay close attention, Jim trots for upwards of a few seconds (probably upwards of 50 feet), but the Southwest sign in the background barely moves from right to left, as if Jim is not running at all. Totally impossible.
Continuity mistake: When the game starts in Arlington the plate umpire is number 76. Later in the game when Jimmy pitches the umpire's number is 82. They do not change home plate umpire unless he is injured.
