Cricket is a bat-and-ball team sport. Many variations exist, with its most popular form played on an oval-shaped outdoor arena known as a cricket field at the centre of which is a rectangular 22-yard (20.12 m) long pitch that is the focus of the game. A game (or match) is contested between two teams of eleven players each. One team bats, trying to score as many runs as possible while the other team bowls and fields, trying to dismiss the batsmen and thus limit the runs scored by the batting team. A run is scored by the striking batsman hitting the ball with his bat, running to the opposite end of the pitch and touching the crease there without being dismissed. The teams switch between batting and fielding at the end of an innings. There are also variations in the length of a game of cricket. In professional cricket this ranges from a limit of 20 overs per side (Twenty20) to a game played over 5 days (Test cricket, which is the highest level of the game). Depending on the form of the match being played, there are different rules that govern how a game is won, lost, drawn or tied. The rules of two-innings games are known as the Laws of Cricket and maintained by the International Cricket Council (ICC) and the Marylebone Cricket Club (MCC); additional Standard Playing Conditions for Test matches and One Day Internationals augment these laws. In one version of Indoor Cricket, matches include just 6 players per side and include two 12-over innings. Cricket was first documented as being played in southern England in the 16th century. By the end of the 18th century, it had developed to the point where it had become the national sport of England. The expansion of the British Empire led to cricket being played overseas and by the mid-19th century the first international matches were being held. The ICC is the game's governing body and currently has 105 member countries. Cricket is most popular in the Test playing countries. Early cricket was at some time or another described as "a club striking a ball (like) the ancient games of club-ball, stool-ball, trap-ball, stob-ball". Cricket can definitely be traced back to Tudor times in early 16th-century England. Written evidence exists of a game known as creag being played by Prince Edward, the son of Edward I (Longshanks), at Newenden, Kent in 1301 and there has been speculation, but no evidence, that this was a form of cricket.
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. 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. A wicket consists of three stumps that are hammered into the ground, and topped with two bails. 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". The essence of the sport is that a bowler delivers the ball from his end of the pitch towards the batsman who, armed with a bat is "on strike" at the other end. The bat is made of wood (usually White Willow) and has the shape of a blade topped by a cylindrical handle. The blade must not be more than 4.25 inches (108 mm) wide and the total length of the bat not more than 38 inches (970 mm). The ball is a hard leather-seamed spheroid with a circumference of 9 inches (230 mm). The hardness of the ball, which can be delivered at speeds of more than 90 miles per hour (140 km/h), is a matter for concern and batsmen wear protective clothing including pads (designed to protect the knees and shins), batting gloves for the hands, a helmet for the head and a box inside the trousers (to protect the crotch area). Some batsmen wear additional padding inside their shirts and trousers such as thigh pads, arm pads, rib protectors and shoulder pads.Best of Cricket
All eleven players on the fielding side take the field together. One of them is the wicket-keeper aka "keeper" who operates behind the wicket being defended by the batsman on strike. Wicket-keeping is normally a specialist occupation and his primary job is to gather deliveries that the batsman does not hit, so that the batsmen cannot run byes. He wears special gloves (he is the only fielder allowed to do so), a box over the groin, and pads to cover his lower legs. Owing to his position directly behind the striker, the wicket-keeper has a good chance of getting a batsman out caught off a fine edge from the bat. He is the only player who can get a batsman out stumped. Apart from the one currently bowling, the other nine fielders are tactically deployed by the team captain in chosen positions around the field. These positions are not fixed but they are known by specific and sometimes colourful names such as "slip", "third man", "silly mid on" and "long leg". There are always many unprotected areas. The captain is the most important member of the fielding side as he determines all the tactics including who should bowl (and how); and he is responsible for "setting the field", though usually in consultation with the bowler. In all forms of cricket, if a fielder gets injured or becomes ill during a match, a substitute is allowed to field instead of him. The substitute cannot bowl, act as a captain or keep wicket. The substitute leaves the field when the injured player is fit to return. If the team that bats last is all out having scored fewer runs than their opponents, the team is said to have "lost by n runs" (where n is the difference between the number of runs scored by the teams). If the team that bats last scores enough runs to win, it is said to have "won by n wickets", where n is the number of wickets left to fall. For instance a team that passes its opponents' score having only lost six wickets would have won "by four wickets". In a two-innings-a-side match, one team's combined first and second innings total may be less than the other side's first innings total. The team with the greater score is then said to have won by an innings and n runs, and does not need to bat again: n is the difference between the two teams' aggregate scores. If the team batting last is all out, and both sides have scored the same number of runs, then the match is a tie; this result is quite rare in matches of two innings a side. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is declared a draw. If the match has only a single innings per side, then a maximum number of deliveries for each innings is often imposed. Such a match is called a "limited overs" or "one-day" match, and the side scoring more runs wins regardless of the number of wickets lost, so that a draw cannot occur. If this kind of match is temporarily interrupted by bad weather, then a complex mathematical formula, known as the Duckworth-Lewis method after its developers, is often used to recalculate a new target score. A one-day match can also be declared a "no-result" if fewer than a previously agreed number of overs have been bowled by either team, in circumstances that make normal resumption of play impossible; for example, wet weather.
