The "rainout" scene was based on actual event. In the late 1960s, Ron Shelton played minor-league ball in the Texas League. Shelton's team was in Amarillo, Texas for a season-ending series. The night before the final game, Shelton, some teammates and some Amarillo players were out partying and decided to go to the stadium and turn on the sprinkler system, thereby flooding the field and ensuring a "rainout". However, the Amarillo team owner rented a helicopter, dried the field, and the game was played.
