Fastpitch is played in sub-elite and elite international, national and state competition, as well as in many association and club competitions. Slowpitch, which is also played competitively, is very popular as a recreational or social sport. A softball field Infield The playing field is divided into fair territory 1  and foul territory 2 . Fair territory is further divided into the infield 3 , and the outfield 4 , and the territory beyond the outfield fence. The infield consists of the diamond and the adjacent space in which the infielders normally play. The outfield is the remaining space between the baselines and between the outfield fence and the infield. The infield is usually 'skinned' (dirt), while the outfield has grass in regulation competitions. The infield is a square (called a diamond) with a base at each corner: home plate, 1 st  base, 2 nd  base and 3 rd  base. The distance for pitching is measured from the rear point of the home plate to the front edge of the pitchers plate, which is centred in a 1.8m (6ft) radius circle. 1   Part of the playing field within and including the 1 st  and 3 rd  base foul lines, from home base to the extreme playing field fence 2  Any part of the playing field that is not included in fair territory 3  The diamond-shaped area in fair territory, formed by the 3 bases and home plate, is normally covered by defensive players (known as infielders) 4  The area outside the diamond but still within the foul lines, covered by defensive players (outfielders)    Softball Field Guidelines Page 2   of 10   Outfield The outfield is the grass area beyond the infield which extends the entire width of the field and all the way to the outfield fence, if there is one. The outfield is in the shape of a quarter-circle and is between the two foul lines. The minimum distance from the apex of home plate to the boundary is 67.06m (220ft) for W omen’s Fastpitch Softball. Field areas How to lay out a Diamond This section serves as an example for laying out a diamond with 18.29m (60ft) bases and a 14.02m (46ft) pitching distance used in open and  junior men’s competitions (see Softball field distances for additional dimensions). 1 To determine the position of home plate, draw a line in the direction it is desired to lay the diamond. Drive a stake at the corner of home plate nearest the catcher. Fasten a cord to this stake and tie knots or otherwise mark the cord at 14.02m (46ft), 18.29m (60ft), 25.86m (84ft 10¼ in) marker and at 36.58m (120ft). 2 Place the cord (without stretching) along the direction line and place a stake at the 14.02m (46ft) marker  –  this will be the front line at the middle of the pitcher's plate. Along the same line, drive a stake at the 25.86m (84ft 10¼ in) marker. This will be the centre of 2 nd  base. For the 19.81m (65ft) base distance, this line will be 28.02m (91ft 11in). 3 Place the 36.58m (120ft) marker at the centre of second base and, taking hold of the cord at the 18.29m (60ft) marker, walk to the right of the direction line until the cord is taut and drive a stake at the 18.29m (60ft) marker  –  this will be the outside corner of 1 st  base and the cord will now form the lines to first and 2 nd  bases. 4 Again, holding the cord at the 18.29m (60ft) marker, walk across the field and in like manner, mark the outside corner of 3 rd  base. Home plate, first base, and third base are wholly inside the diamond. 5 To check the diamond, place the home plate end of the cord at the 1 st  base stake and the 36.58m (120ft) marker at 3 rd  base. The 18.29m (60ft) marker should now check at home plate and 2 nd  base. 6 In laying out a 19.81m (65 ft) base path diamond, follow the same procedure with the following substitute dimensions: 19.81m (65ft), 39.62m (130ft), and 28.02m (91ft 11 in).
