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 demarc. Law 9 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.
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 they are 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 part of the bowler's front foot in the delivery stride must fall behind the popping crease (see below).
The term popping crease refers to the early history of the game of cricket, when batsmen used to have to 'pop' their bats into a small hole that was located in the middle of the crease for a run to count. For a player to run a batsman out, he had to pop the ball into the hole before the bat was grounded in it.
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.
For the fielding side
For the fielding team the popping crease is used as one test of whether the bowler has bowled a no ball. To avoid a no ball, some part of the bowler's front foot in the delivery stride (that is, the stride when he releases the ball) must be behind the popping crease, although it does not have to be grounded. The foot must be behind the line, rather than upon, it as the line itself is considered out of bounds. This has given rise to the term "the line belongs to the umpire."
For the batting side
For a batsman the popping crease - which can be referred to as the batting crease in the context of batting - determines whether they have been stumped or run out. This is described in Laws 29, 38, and 39 of the laws of cricket. Both involve the wicket being put down before a batsman can touch his body or bat to the ground behind the popping crease and make his ground and return safely from his run. A 2010 amendment to Law 29 clarified the circumstance where the wicket is put down while a batsman has become fully airborne after having first made his ground; the batsman is regarded to not be out of his ground.
- If the batsman facing the bowler (the striker) steps out of his ground to play the ball but misses and the wicket-keeper takes the ball and puts down the wicket, then the striker is out stumped.
- If a fielder puts down either wicket whilst the batsmen are running between the wickets (or otherwise forward of the popping crease during the course of play), then the batsman nearest the downed wicket is out run out. There is no limit of how far a bowler may bowl behind the crease.
The popping crease is visible here, with England's Marcus Trescothick playing a shot that has involved him moving forward over his own crease to intercept the ball. In taking a successful run, he must ground his bat behind the corresponding crease at the other end of the pitch, and his batting partner must in turn ground himself behind Trescothick's crease. Should Trescothick have ventured beyond his crease in playing his shot, he risked being stumped.
David Masters bowling, he must ground some part of his foot behind his popping crease and within the return creases for the ball to be a legal delivery. As a member of the fielding side, he can also attempt to run out a batsman by breaking the stumps with the ball before the batsman manages to return to the popping crease.
Here the batsman has played a shot and missed, with the wicketkeeper receiving the ball. The 'keeper, believing that in playing his shot the batsman has ventured beyond his popping crease, has broken the stumps with the ball in an attempt to dismiss him 'stumped'. He is appealing to the umpire to review and either accept or refuse the dismissal. It now falls to the umpire to adjudge whether the batsman had indeed ventured beyond his crease, a decision that in modern cricket is assisted by technology and replays.
Four return creases are drawn, one on each side of each set of stumps. The return creases lie perpendicular to the popping crease and the bowling crease, 4 feet 4 inches (1.32 m) either side of and parallel to the imaginary line joining the centres of the two middle stumps. Each return crease line starts at the popping crease but the other end is considered to be unlimited in length and must be marked to a minimum of 8 feet (2.44 m) from the popping crease.
The return creases are primarily used to determine whether the bowler has bowled a no ball. To avoid a no ball, some part of the bowler's back foot in the delivery stride must land within and not touch the return crease. This is to stop the bowler from bowling at the batsmen from an unfair angle (i.e. diagonally).
Using the crease
Though the relatively small size of the crease is such that they limit the degree to which a batsman or a bowler can alter where they stand to face or deliver a ball, there is a degree of latitude afforded whereby both can move around the crease as long as they remain within the aforementioned confines. Batsmen 'use the crease' when they move toward leg or off, before or while playing a shot. Bowlers 'use the crease' by varying the position of their feet, relative to the stumps, at the moment of delivery. In so doing, they can alter the angle of delivery and the trajectory of the ball.
