In baseball, ground rules are special rules particular to each baseball park (grounds) in which the game is played. Unlike the well-defined playing field of most other sports, the playing area of a baseball field extends to an outfield fence in fair territory and the stadium seating in foul territory. The unique design of each ballpark, including fences, dugouts, bullpens, railings, stadium domes, photographer's wells and TV camera booths, requires that rules be defined to handle situations in which these objects may interact or interfere with the ball in play or with the players.
Major League Baseball has defined a set of "universal ground rules" that apply to all MLB ballparks; individual ballparks have the latitude to set ground rules above and beyond the universal ground rules, as long as they do not directly contradict each other. Additionally, a set of universal ground rules exists for the five MLB stadiums with retractable roofs, with the individual ballparks able to set additional rules.
The term ground rule double is often applied to a batted ball that bounces over the outfield fence in fair territory, although some commentators and writers shun the term because league-wide rules, not ground rules, apply in this case.
Famous quotes containing the words ground and/or rules:
“To people off alone, as we were, there is something stirring about finding evidences of human labour and care in the soil of an empty country. It comes to you as a sort of message, makes you feel differently about the ground you walk over every day.”
—Willa Cather (1873–1947)
“The young break rules for fun. The old for profit.”
—Mason Cooley (b. 1927)
