In her opening monologue, Annie says, "There are 108 beads in a Catholic rosary and there are 108 stitches in a baseball." While a set of Hindu or Buddhist prayer beads has 108 beads (and, indeed, the number 108 figures prominently in Eastern religions), the most commonly used Catholic rosary has only 59 beads.
In the scene when Nuke first shakes off Crash's sign, Crash can be seen walking back towards the plate and putting his mask on. When he arrives at the plate and says "fastball" to the opposing batter, he begins to put his mask on again.
When Crash throws the 8-ball at the mirror after Nuke tells him he's been called up the show. At first, a portion of the broken mirror remains on the wall, then in the next shot it is virtually all gone, then back again but with different broken pieces remaining.
In the dugout, Crash removes his equipment, preparing to go up to bat as he gives Nuke a dressing down. His chest protector is still on as he gets up, his hands empty. A moment later, he's on the dugout steps putting on batting gloves, a bat is leaning on him, and his chest protector is off.
In the opening scene when Annie is walking into the stadium on opening night, the team is warming up on the field and the catcher is wearing #8 (which is Crash's number in the movie with the Bulls), but the catcher that started the season before Crash shows up is shown wearing #10 in the game.
When the local radio station is doing a simulation of a road game, the announcer's assistant, who is receiving the play-by-play via telephone, writes "DOUBLE TO LEFT" on a piece of paper. The handwriting on the paper changes from the time she writes it down to when she holds up the paper for the announcer to see.
When Nuke and Annie argue in her kitchen, she is in the background and he is in the foreground, meaning he has to walk past her as he heads for the door. But we never see him walk past her, even though she watches him head for the door.
When Crash tells Nuke to hit the Bull Mascot Nuke hits the Bull with the first pitch of the at bat. Then all of the sudden the next pitch, which is a strike down the middle, is strike three and the batter is out.
After catching a pop-up behind home plate, Crash tells Nuke to intentionally hit the Mascot. Nuke hits the mascot, Crash warns the batter, "I wouldn't dig in if I were you." The next pitch is a swinging strike, the batter is called out and Crash throws to 3rd base. At this point the count on the batter is only 1-1. The batter has not struck out yet.
When Nuke is pitching and his father at the game ... the signs in the outfield change. When the batter is hitting, there is a sign in the outfield that reads "Sheraton University Center", but when Crash goes out to talk to Nuke, this sign is no longer there. It appears to have been filmed at a different ballpark.
When Crash runs towards the backstop to catch a pop foul, he barely catches it (ice cream cone-type catch) as you can clearly see the ball sticking out of his glove. In the next shot, you see him taking the ball from deep in the pocket of his glove.
Near the end of the film when Annie is returning home (the old James Manning house at 911 N. Mangum Street in Durham) from the ballpark in the rain (umbrella in hand) and sees Crash on her porch swing, Annie approaches her house from the north, the wrong direction. The old Durham Athletic Park, where the film was shot, is located in the 500-block of W. Corporation Street which is south and west of the house.
When Crash tells Nuke to hold the ball like an egg, Crash returns to his position and holds down two fingers to signify that he wants Nuke to throw a curveball. Since there is a runner at second base at the time, a catcher would throw down a series of signs, so that the runner at second can't steal the sign and signal the batter on what the next pitch is going to be.
Nuke says the parent major league team is expanding its roster and he has been called up to "the show." The Bulls (and Asheville Tourists, Crash's new team) continue to play. In reality, roster expansion coincides with the end of the minor league season (Labor Day). Also, players for high A teams typically do not go directly to the majors (skipping two levels).
Skip tells Crash that they're letting him go to bring up a catcher from Bluefield. At the filming, the Durham Bulls were a high single-A affiliate of the Atlanta Braves, while Bluefield was the Appalachian League (rookie) affiliate of the Baltimore Orioles. The Braves Appalachian League affiliate at the time was the Pulaski (Va.) Braves.
The first scene where we see Annie driving a car is the scene where the bus is leaving the parking lot. Annie waves and gets into a brown mid 1980s two door Pontiac Sunbird. But we never see the Pontiac Sunbird again in the movie. Suddenly, later in the movie, she is driving the old blue Volvo, which remains the car she drives throughout the rest of the movie.
About 21 minutes into the movie Annie and Crash are in her bedroom ans she puts an Édith Piaf record on. But the record player is clearly a 78 RPM antique, and the disk is clearly a modern 33 rpm LP with multiple cuts.
When Crash tells Nuke to hit the bull mascot, which is standing behind the plate, you can see the breath of both players, as if it is winter. In fact, it is supposed to be deep into the summer, as all fans are wearing summer attire, and, of course, it's summer baseball season.
When the players are having their conference at the mound in the game where Nook's dad is at the game and Jose's glove has a curse on it, Crash has his helmet on backwards so that the catcher's mask can fit on it. The back of the helmet has #20 on it instead of his #8.
