Visible crew/equipment: On some shots which look back at Ray when he's driving his pickup, it can be clearly seen at the bottom of the picture that the front wheels of the pickup are sitting on a trailer, which is itself being towed by the camera vehicle.
Continuity mistake: When Annie and Ray are laying in the newly completed ball field, and Annie is drinking a glass of wine, it is sunset. The sun has gone down and the sky is just the faintest of pink on the horizon, the rest of the sky is a strong blue tone. Yet, when the camera cuts to a long shot, same angle of Ray and Annie, the horizon is now a brilliant red-orange taking up nearly a third of the sky.
Character mistake: Chick Gandil mispronounces Eddie Cicotte's name, calling him "Si-coty" instead of "See-cot."
Continuity mistake: In the scene where Ray has a catch with his father, Ray's brother-in-law's Jeep can be seen parked near the light pole along the third base line. In the next shot, the Jeep isn't there. When the shot again changes and the camera pans back, the Jeep is back by the pole.
Continuity mistake: When Ray and Joe Jackson first take batting practice in the field there are five bats against the backstop. To their left is the bag with the remaining bats, the bag at first has the appearance that there is the strong outline of a bat or a bat behind the bag, yet when Joe goes to retrieve another bat the bag is loose and in an entirely different shape.
Continuity mistake: When Ray and Annie are at the PTA meeting, it is night when they go inside, but when they come out after Annie gets into the argument with the other woman, it is day (there is sunlight coming through the windows).
Continuity mistake: The grocery bag in back of the truck shows a red and white milk carton sticking out of bag. In a following shot the grocery bag no longer has the milk carton sticking out of the top. Then upon entering the house, the same grocery bag now has a blue and white milk carton sticking out, plus other items not seen before.
Continuity mistake: In the scene Costner is chopping up his corn crop with a flail hopper, the PTO that drives the machine is not rotating.
Continuity mistake: At the end of the film, when Ray is saying "Good-night" to John, the sun has set and the sky is cloudless and pink just along the horizon. In the next shot, when Ray asks, "Dad" for "a catch" the sky is much brighter and there are many clouds reflecting the now setting sun.
Factual error: When Ray is in the feed store, he picks up a bag of seeds from the counter and casually walks out. These bags of seeds weigh 50 pounds, so to lift it in the manner he did would require a great deal of strength.
