<P> In the sport of cricket, the crease is a certain area demarcated by white lines painted or chalked on the field of play, and pursuant to the rules of cricket they help determine legal play in different ways for the fielding and batting side . They define the area within which the batsmen and bowlers operate . The term crease may refer to any of the lines themselves, particularly the popping crease, or to the region that they demark . Law 7 of the Laws of Cricket governs the size and position of the crease markings, and defines the actual line as the back edge of the width of the marked line on the grass, i.e., the edge nearest to the wicket at that end . </P> <P> Four creases (one popping crease, one bowling crease, and two return creases) are drawn at each end of the pitch, around the two sets of stumps . The batsmen generally play in and run between the areas defined by the creases at each end of the pitch . The bowling creases lie 22 yards (66 feet or 20.12 m) away, and marks the other end of the pitch . For the fielding side, the crease defines whether there is a No ball because a fielder has encroached on the pitch or the wicket - keeper has moved in front of the wicket before he is permitted to do so . In addition, historically part of the bowler's back foot in the delivery stride was required to fall behind the bowling crease to avoid a delivery being a No ball . This rule was replaced by a requirement that the bowler's front foot in the delivery stride must land with some part of it behind the popping crease (see below). </P> <P> The origin of creases is uncertain but they were certainly in use by the beginning of the 18th century when they were created by scratch marks, the popping crease being 46 inches in front of the wicket at each end of the pitch . In the course of time, the scratches became cuts which were an inch deep and an inch wide . The cut was in use until the second half of the 19th century . Sometime during the early career of Alfred Shaw, he suggested that the creases should be made by lines of whitewash and this was gradually adopted through the 1870s . </P> <P> The origin of the term "popping crease" is unknown . One popping crease is drawn at each end of the pitch in front of each set of stumps . The popping crease is 4 feet (1.22 m) in front of and parallel to the bowling crease . Although it is considered to have unlimited length (in other words, runs across the entire field) the popping crease must be marked to at least 6 feet (1.83 metres) perpendicular to the pitch, on either side of the middle of the pitch . </P>
