Rules and Game Play

Laws Of Cricket

The laws of cricket are a set of rules established by the Marylebone Cricket Club (MCC) which describe the laws of cricket worldwide, to ensure uniformity and fairness. There are currently 42 laws, which outline all aspects of how the game is played from how a team wins a game, how a batsman is dismissed, through to specifications on how the pitch is to be prepared and maintained. The MCC is a private club based in London in England and is no longer the game’s official governing body; however the MCC retains the copyright in the laws of the game and only the MCC may change the laws, although nowadays this would usually only be done after discussions with the game’s global governing body the International Cricket Council (ICC). Cricket is one of the few sports for which the governing principles are referred to as ‘Laws’ rather than as ‘Rules’ or ‘Regulations’. However regulations to supplement and/or vary the laws may be agreed for particular competitions.

Rules and Game-play

A cricket match is played between two teams (or sides) of eleven players each on a field of variable size and shape. The ground is grassy and is prepared by groundsmen whose jobs include fertilising, mowing, rolling and levelling the surface. Field diameters of 137–150 metres (150–160 yd) are usual. The perimeter of the field is known as the boundary and this is sometimes painted and sometimes marked by a rope that encircles the outer edge of the field. The Laws of Cricket do not specify the size or shape of the field but it is often oval – one of cricket’s famous venues is called The Oval.

The key action takes place in a specially prepared area of the field (generally in the centre) that is called the pitch. A run is scored when the batsman has run the length of the pitch after hitting the ball with his bat, although as explained below there are many ways of scoring runs. If the batsmen are not attempting to score any more runs, the ball is dead and is returned to the bowler to be bowled again.

Before play commences, the two team captains toss a coin to decide which team shall bat or bowl first. The captain who wins the toss makes his decision on the basis of tactical considerations which may include the current and expected field and weather conditions.

The bowling side seeks to dismiss the batsmen by various means until the batting side is all out, whereupon the side that was bowling takes its turn to bat and the side that was batting must take the field.

In professional matches, there are 15 people on the field while a match is in play. Two of these are the umpires who regulate all on-field activity. Two are the batsmen, one of whom is the striker as he is facing the bowling; the other is called the non-striker. The roles of the batsmen are interchangeable as runs are scored and overs are completed. The fielding side has all 11 players on the field together. One of them is the bowler, another is the wicketkeeper and the other nine are called fielders. The wicketkeeper (or keeper) is nearly always a specialist but any of the fielders can be called upon to bowl.

Objectives

The objective of each team is to score more runs than the other team and to completely dismiss the other team. In limited overs cricket, winning the game is achieved by scoring the most runs, even if the opposition has not been completely dismissed. In Test cricket, it is necessary to score the most runs and dismiss the opposition twice in order to win the match, which would otherwise be drawn.

Pitch, Wickets and Creases

At either end of the pitch, 22 yards (20 m) apart, are placed the wickets. These serve as a target for the bowling (aka fielding) side and are defended by the batting side which seeks to accumulate runs. The pitch is 22 yards (20 m) or one chain in length between the wickets and is 10 feet (3.0 m) wide. It is a flat surface and has very short grass that tends to be worn away as the game progresses. The “condition” of the pitch has a significant bearing on the match and team tactics are always determined with the state of the pitch, both current and anticipated, as a deciding factor.

Each wicket consists of three wooden stumps placed in a straight line and surmounted by two wooden crosspieces called bails; the total height of the wicket including bails is 28.5 inches (720 mm) and the combined width of the three stumps is 9 inches (230 mm).


Four lines, known as creases, are painted onto the pitch around the wicket areas to define the batsman’s “safe territory” and to determine the limit of the bowler’s approach. These are called the “popping” (or batting) crease, the bowling crease and two “return” creases.



The stumps are placed in line on the bowling creases and so these must be 22 yards (20 m) apart. A bowling crease is 8 feet 8 inches (2.64 m) long with the middle stump placed dead centre. The popping crease has the same length, is parallel to the bowling crease and is 4 feet (1.2 m) in front of the wicket. The return creases are perpendicular to the other two; they are adjoined to the ends of the popping crease and are drawn through the ends of the bowling crease to a length of at least 8 feet (2.4 m).


When bowling the ball, the bowler’s back foot in his “delivery stride” must land within the two return creases while his front foot must land on or behind the popping crease. If the bowler breaks this rule, the umpire calls “No ball”.
The importance of the popping crease to the batsman is that it marks the limit of his safe territory for he can be stumped or run out (see Dismissals below) if the wicket is broken while he is “out of his ground”.
