Softball

The playing field is divided into 'fair territory' and 'foul territory'. Fair territory is further divided into the 'infield', and the 'outfield', and the territory beyond the outfield fence. The field is defined by 'foul lines' that meet at a right angle at 'home plate'. The minimum length of the baselines varies classification of play (see below for official measurements). A fence running between the baselines defines the limits of the field; this fence is equidistant from home plate at all points. Behind home plate is a 'backstop'. It must be between 25 and 30 feet (7.62 and 9.14 meters) behind home plate depending on the type of division that is playing. 'Home Plate' is one corner of a diamond with 'bases' at each corner. The bases other than home plate are 15 in (38 cm) square, of canvas or a similar material, and not more than 5 in (13 cm) thick. The bases are usually securely fastened to the ground. The bases are numbered counter clockwise as first base, second base, and third base. Often, but not always, outside first base (that is, in foul territory) and adjacent and connected to it there is a contrast-colored "double base" or "safety base". It is intended to prevent collisions between the first baseman and the runner. The runner runs for the foul portion of the double base after hitting the ball while the fielding team tries to throw the ball to the regular first base before the runner reaches the safety base. However, not all softball diamonds have these safety bases and they are much more common in women's softball than in men's. The double base is required in ISF championships.
