Bat and Ball

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.




Umpires and Scorers

The game on the field is regulated by two umpires, one of whom stands behind the wicket at the bowler’s end, the other in a position called “square leg”, a position 15–20 metres to the side of the “on strike” batsman. When the bowler delivers the ball, the umpire at the wicket is between the bowler and the non-striker. The umpires confer if there is doubt about playing conditions and can postpone the match by taking the players off the field if necessary, for example rain or deterioration of the light.

Off the field and in televised matches, there is often a third umpire who can make decisions on certain incidents with the aid of video evidence. The third umpire is mandatory under the playing conditions for Test matches and limited overs internationals played between two ICC full members. These matches also have a match referee whose job is to ensure that play is within the Laws of cricket and the spirit of the game.

Off the field, the match details including runs and dismissals are recorded by two official scorers, one representing each team. The scorers are directed by the hand signals of an umpire. For example, the umpire raises a forefinger to signal that

the batsman is out (has been dismissed); he raises both arms above his head if the batsman has hit the ball for six runs. The scorers are required by the Laws of cricket to record all runs scored, wickets taken and overs bowled. In practice, they accumulate much additional data such as bowling analyses and run rates.

Innings

The innings (ending with ‘s’ in both singular and plural form) is the term used for the collective performance of the batting side. In theory, all eleven members of the batting side take a turn to bat but, for various reasons, an “innings” can end before they all do so.

Depending on the type of match being played, each team has one or two innings apiece. The term “innings” is also sometimes used to describe an individual batsman’s contribution (“he played a fine innings”).

The main aim of the bowler, supported by his fielders, is to dismiss the batsman. A batsman when dismissed is said to be “out” and that means he must leave the field of play and be replaced by the next batsman on his team. When ten batsmen have been dismissed (i.e., are out), then the whole team is dismissed and the innings is over. The last batsman, the one who has not been dismissed, is not allowed to continue alone as there must always be two batsmen “in”. This batsman is termed “not out”.

An innings can end early for three reasons: because the batting side’s captain has chosen to “declare” the innings closed (which is a tactical decision), or because the batting side has achieved its target and won the game, or because the game has ended prematurely due to bad weather or running out of time. In each of these cases the team’s innings ends with two “not out” batsmen, unless the innings is declared closed at the fall of a wicket and the next batsman has not joined in the play.

In limited overs cricket, there might be two batsmen still “not out” when the last of the allotted overs has been bowled.

Overs

The bowler bowls the ball in sets of six deliveries (or “balls”) and each set of six balls is called an over. This name came about because the umpire calls “Over!” when six balls have been bowled. At this point, another bowler is deployed at the other end, and the fielding side changes ends while the batsmen do not. A bowler cannot bowl two successive overs, although a bowler can bowl unchanged at the same end for several overs. The batsmen do not change ends and so the one who was non-striker is now the striker and vice-versa. The umpires also change positions so that the one who was at square leg now stands behind the wicket at the non-striker’s end and vice-versa.
