There was no rule against that activity as such, so he got away with it, until one day when he took it to an extreme, rolling it out when the opponents batted, and reeling it back when the Brewers batted. Veeck reported that the league passed a rule against it the very next day. It has been speculated that the story was made up by Veeck; research by two members of the Society for American Baseball Research revealed no evidence of either a movable fence or any gear (pulleys, etc.) required for it to work. As early as 1944, newspapers were reporting on the story of the screens, though specifics have been elusive.
