Foul territory is a term used in baseball to refer to the areas outside the foul lines that run from home plate to first and third bases. Some synonyms that can be used to describe foul territory include out-of-bounds area, non-scoring zone, beyond the playing area, and off-limit space. The term foul ground can also be used to refer to this area. In addition, some baseball enthusiasts use the term dead ball territory to describe foul territory because a ball hit into this area is considered a dead ball and cannot be played by fielders. Regardless of the terminology used, foul territory is an important aspect of the game that can impact the outcome of the game.
