1992 Pittsburgh Pirates Ground Rules at Three Rivers Stadium
The 1992 Pittsburgh Pirates Three Rivers Stadium Ground Rules page from the National League Green Book outlines specific regulations governing play at Three Rivers Stadium, which hosted its first game on July 16, 1970. A notable regulation states that any ball hitting the foul-line screen above the outfield fence is designated as a home run. Additionally, for grounding rules involving the photographers' benches located at the outfield ends of the home and visiting clubs’ areas, these benches are included as part of the player’s bench. Furthermore, if a ball strikes the screen in front of the right or left bullpen, it remains in play. If a ball becomes lodged in the screen in front of either bullpen, the play is awarded two bases.
