Corrected entry: When the pitchers are playing catch in front of Brian Denehey, when Freddie Prinze Jr gets up to to throw to Matthew Lillard and is standing with the other pitchers, his glove is on his left hand, indicating he is a right handed pitcher, but in the next scene his glove is on the right hand, which it continues to be on throughout the rest of the movie, since he is supposed to be a left handed pitcher in the movie.
Corrected entry: Even if you ignore the fact that no serious baseball player would ever leave a game in which he's pitching a no-hitter in the ninth inning, the fact remains that there were only two outs remaining. In the time it takes Freddie Prinze Jr. to call in the relief pitcher and explain his love for Jessica Biel to his team, the game might have already been over. If he had just continued pitching he could've finished the game and still had time to chase after Biel.
Corrected entry: In the scene where Freddie and Matthew Lillard are at the Oasis bar, and Matthew is getting ready to go back home, Freddie is saying goodbye to Matthew because he's leaving the bar to go hang out with Jessica Biel, It's mentioned several times that Matthew is taking a bus home, but when Freddie says bye to him, he tells him to have a nice flight.
Corrected entry: In baseball when a hitter strikes out looking a backward "K" is recorded in the score book, and a forward "K" is used when they strike out swinging. Well, at the end of the movie during Freddie's no hitter, as he strikes hitters out, the two the guys in the crowd are hanging "K's" up on the shed the wrong way.
