1986 Pittsburgh Pirates Ground Rules for Three Rivers Stadium Baseball
The page from the 1986 National League Green Book outlines the ground rules for the Pittsburgh Pirates at Three Rivers Stadium, which hosted its first game on July 16, 1970. It specifies that any ball hitting the foul-line screen above the outfield fence is deemed a home run. Additionally, the regulations clarify that the photographer's benches located at the outfield ends of both home and visiting teams' dugouts are considered part of the player's bench for the purposes of ground rules. The document also describes scenarios involving fair balls: if they strike the screen in front of the right or left field bullpen, the ball remains in play; if they stick in the screen, the batter is awarded two bases; and if they go through or under the screen, the batter similarly receives two bases.
