A pitch or a sports ground is an outdoor playing area for various sports. The term pitch is most commonly used in British English, while the comparable term in American and Canadian English is playing field or sports field.
In most sports the official term is field of play, although this is not regularly used by those outside refereeing/umpiring circles. The field of play generally includes out-of-bounds areas that a player is likey to enter while playing a match, such as the area beyond the touchlines in association football and rugby or the sidelines in American and Canadian football, or the "foul territory" in baseball.
