Softball is a variant of baseball played with a larger ball on a smaller field. There are two types of softball. In the most common type, slow-pitch softball, the ball, sometimes larger than the standard 12 inches, must arch on its path to the batter; there are 10 players in a team; and bunting and stealing are prohibited. In fastpitch softball, the pitch is fast, there are nine players on the field at one time, and bunting and stealing are permitted. Softball rules vary somewhat from those of baseball. Two major differences are that the ball must be pitched underhand and there are seven innings instead of nine constitute a regulation game.
