A cricket ball

A cricket ball is a hard, solid ball used to play cricket. A cricket ball consists of a cork core wound with string then a leather cover stitched on, and manufacture is regulated by cricket law at first-class level. The trajectory of a cricket ball when bowled, through movement in the air, and off the ground, is influenced by the action of the bowler and the condition of the ball and the pitch, while working on the cricket ball to obtain optimal condition is a key role of the fielding side. The principal method through which the batter scores runs is by hitting the ball, with the bat, into a position where it would be safe to take a run, or by directing the ball through or over the boundary. Cricket balls are harder and heavier than baseballs. [1]

Contents

In Test cricket, professional domestic games that spread over a multitude of days, and almost the entirety of amateur cricket, the traditional red cricket ball is normally used. In many one day cricket matches, a white ball is used instead in order to remain visible under floodlights, and since 2010, pink has been introduced to contrast with players' white clothing and for improved night visibility during day/night Test matches. [2] Training balls of white, red and pink are also common, and tennis balls and other similar-sized balls can be used for training or informal cricket matches. During cricket matches, the quality of the ball changes to a point where it is no longer usable, and during this decline its properties alter and thus can influence the match. Altering the state of the cricket ball outside the permitted manners designated in the rules of cricket is prohibited during a match, and so-called "ball tampering" has resulted in numerous controversies.

Injuries and fatalities have been caused by cricket balls during matches. [3] The hazards posed by cricket balls were a key motivator for the introduction of protective equipment.

Manufacture

British Standard BS 5993 specifies the construction details, dimensions, quality and performance of cricket balls.

A cricket ball is made with a core of cork, which is layered with tightly wound string, and covered by a leather case with a slightly raised sewn seam. In a top-quality ball suitable for the highest levels of competition, the covering is constructed of four pieces of leather shaped similar to the peel of a quartered orange, but one hemisphere is rotated by 90 degrees with respect to the other. The "equator" of the ball is stitched with string to form the ball's prominent seam, with six rows of stitches. On international level balls manufactured by Dukes, and SG, the two halves are hand stitched together using three seams on each half. On the ball made by Kookaburra only the inner two seams are used to hold the two halves together. The outer four seams are produced by machine and their only purpose is to provide additional grip for the bowlers fingers. [4] The remaining two joins between the leather pieces are stitched internally forming the quarter seam. Lower-quality balls with a two-piece covering are also popular for practice and lower-level competition due to their lower cost.

The nature of the cricket ball slightly varies with its manufacturer. White Kookaburra balls are used in one-day and Twenty20 international matches, while red Kookaburras are used in test matches played in most of the twelve test-playing nations, [6] except for the West Indies, Ireland and England, who use Dukes, and India, who use SG balls. [7]

Use

Colour

White balls are used in many limited overs cricket matches, especially those involving floodlights (day/night games). This is because a red ball under yellow lights takes on a brownish colour which is very similar to the colour of the pitch. White ball 2.JPG

Cricket balls are traditionally red, and red balls are used in Test cricket and First-class cricket but proposals to introduce other colours date back at least as early as 1937. [8]

White balls were introduced when one-day matches began being played at night under floodlights, as they are more visible at night; all professional one-day matches are now played with white balls, even when they are not played at night. The white balls have been found to behave differently from the red balls:[ citation needed ] most notably, they swing a lot more during the first half of an innings than the red balls, and they deteriorate more quickly. Manufacturers claim that white and red balls are manufactured using the same methods and materials, [2] other than the dyeing of the leather. Another problem associated with white cricket balls used in One Day Internationals is that they quickly become dirty or dull in colour, which makes it more difficult for batters to sight the ball after 30–40 overs of use. [9] [10] Since October 2012, this has been managed by the use of two new white balls in each innings, with a different ball used from each bowling end; the same strategy was used in the 1992 and 1996 Cricket World Cups. Between October 2007 and October 2012, the issue had been managed using one new ball from the start of the innings, then swapping it at the end of the 34th over with a "reconditioned ball", which was neither new nor too dirty to see. Before October 2007, except during 1992 and 1996 World Cups, only one ball was used during an innings of an ODI and it was at the umpires' discretion to change the ball if it was difficult to see. [11]

Pink balls were developed in the 2000s to enable Tests and first-class matches played at night. The red ball is unsuited to night tests due to poor visibility, and the white ball is unsuited to first-class cricket because it deteriorates rapidly and cannot be used for eighty overs as specified in the rules, also the white ball colour would clash with the traditional white clothes worn. The pink ball was designed to provide a satisfactory compromise on these issues. It is still considered more difficult to see than a white ball; and the leather is more heavily dyed than a red ball, which better preserves its colour and visibility as it wears but also gives it slightly different wear characteristics. It has performed well enough in testing and first-class cricket to be approved for use in international cricket. [12] A pink ball was used for the first time in an international match in July 2009 when the England Women's team defeated Australia in a one-day match at Wormsley, [13] and a pink ball was used in a day-night Test match for the first time in November 2015. Other colours were also experimented with, such as yellow and orange (glowing composite), for improved night visibility, but pink proved to be the preferred option.

Current status

As of 2014, the ball used in Test match cricket in England had a UK recommended retail price of £100. [14] In test match cricket this ball is used for a minimum of 80 overs (theoretically five hours and twenty minutes of play), after which the fielding side has the option of using a new ball. In professional one day cricket of 50 overs per innings, at least four new balls are used for each match (two in each innings, one for each bowling end). T-20 cricket uses two new balls, one per innings. Amateur cricketers often have to use old balls, or cheap substitutes, in which case the changes in the condition of the ball may be different from professional cricket.

There are three main manufacturers of cricket balls used in international matches: Kookaburra, Dukes and SG. The manufacturer of the red (or pink) balls used for Tests varies depending on location: India uses SG; England, Ireland and the West Indies use Dukes; and all other countries use Kookaburra. The different manufacturers' balls behave differently: for instance Dukes balls have a prouder seam and will tend to swing more than Kookaburra balls [15] – providing a home advantage when playing against a team unfamiliar with the ball. All limited overs international matches, regardless of location, are played with white Kookaburra balls. [16] White Dukes balls were used at the 1999 Cricket World Cup, but the ball behaved more erratically than the Kookaburra and white Dukes have not been used since. Domestic competitions may use a domestic manufacturer: for example, Pakistan uses Grays balls in its first-class competitions. [17] [18]

Cricket balls can be bowled at over 160km/h (100mph) by pace bowlers and made to deviate from a straight course, both in the air (known as 'swinging') and off the ground (known as 'seaming'). A spin bowler bowls at a slower speed, but imparts lateral revolutions on the ball at the point of delivery, so that when it bounces it deviates from a straight course more significantly than other methods. As cricket bats have become thicker, the ball can now be hit well over 100 metres (300 ft) before touching the ground.

Cricket commentator and former Test bowler Simon Doull noted that cricket balls produced after Cricket World Cup 2015 produced a lot less swing regardless of manufacturer. This was said to be apparent in 2017 ICC Champions Trophy, even on traditionally swing-friendly British pitches, particularly with white balls, but the former West Indian bowler Ian Bishop was unwilling to support this. [19]

Condition of a cricket ball

A new cricket ball Cricketball.png
A new cricket ball

In Test cricket and T20 cricket, a new ball is used at the start of each innings in a match. In one-day cricket, two new balls, one from each end, are used at the start of each innings. A cricket ball may not be replaced except under specific conditions described in the Laws of Cricket :

The ball is not replaced if it is hit into the crowd – the crowd must return it. If the ball is damaged, lost, or illegally modified, it will be replaced by a used ball in a similar condition to the replaced ball. A new ball can only be used after the specified minimum number of overs have been bowled with the old one.

Because a single ball is used for an extended period of play, its surface wears down and becomes rough. The bowlers may polish it whenever they can, usually by rubbing it on their trousers, producing the characteristic red stain that can often be seen there. However, they will usually only polish one side of the ball, in order to create 'swing' as it travels through the air. They may only apply sweat to the ball as they polish it. The practice of applying saliva has been banned by the ICC during the ongoing COVID-19 pandemic. In a June 2020 press release, the ICC announced that "A team can be issued up to two warnings per innings but repeated use of saliva on the ball will result in a 5-run penalty to the batting side. Whenever saliva is applied to the ball, the umpires will be instructed to clean the ball before play recommences". [20] The MCC conducted research during the period that shining the ball using saliva was banned, and they concluded that "there was little or no impact on the amount of swing that bowlers were getting". Therefore, in March 2022, the practice of shining the ball using saliva was banned. [21]

The seam of a cricket ball can also be used to produce different trajectories through the air, with the technique known as swing bowling, or to produce sideways movement as it bounces off the pitch, with the technique known as seam bowling.

Since the condition of the cricket ball is crucial to the amount of movement through the air a bowler can produce, the laws governing what players may and may not do to the ball are specific and rigorously enforced. The umpires will inspect the ball frequently during a match. If the ball is out of shape due to normal wear and tear due to batting and ball hitting the pitch, a ball of similar usage and condition will be used as a replacement: e.g. a ball about 30 overs old will be replaced by a ball about the same age.

It is illegal for a player to:

Despite these rules, it can be tempting for players to gain an advantage by breaking them. There have been a handful of incidents of so-called ball tampering at the highest levels of cricket.[ citation needed ]

A new cricket ball is harder than a worn one and is preferred by fast bowlers because of the pace and bounce of the ball off the pitch as well as the seam movement. Older balls tend to spin more as the roughness grips the pitch more when the ball bounces, so spin bowlers prefer to use a worn ball, though a ball of about 8–10 overs old is still useful to a spinner as it can get more drift in the air. Uneven wear on older balls may also make reverse swing possible. A captain may delay the request for a new ball if they prefer to have spin bowlers operating but usually asks for the new ball soon after it becomes available.

Dangers of cricket balls

Cricket balls are hard and potentially lethal, so most of today's batters and close fielders often wear protective equipment. Cricket ball injuries are fairly frequent, including eye (with some players having lost eyes), [22] head and face, [23] finger and toe, [24] teeth [25] and testicular injuries. [24]

Frederick, Prince of Wales (1707–1751) is often said to have died of complications after being hit by a cricket ball, although the connection between the incident and his actual cause of death is unproven. Glamorgan player Roger Davis was seriously injured by a ball in 1971 when he was hit on the head while fielding. [26] The Indian batter Nariman 'Nari' Contractor had to retire from the game after being hit on the head by a ball in the West Indies in 1962. [27]

In 1998, Indian cricketer Raman Lamba died when a cricket ball hit his head in a club match in Dhaka. [28] Lamba was fielding at forward short leg without a helmet when a ball struck by batter Mehrab Hossain hit him on the head and rebounded to wicket-keeper Khaled Mashud.

A cricket umpire, Alcwyn Jenkins, died in 2009 in Swansea, Wales after being hit on the head by a ball thrown by a fielder. [23]

On 27 October 2013, South African cricketer Darryn Randall died after being hit on the head by the ball while batting. He collapsed immediately and was rushed to the Victoria Hospital in rural Alice, but the medical staff could not revive him.[ citation needed ]

In November 2014, Australia and South Australia batter Phillip Hughes died at the age of 25 at a Sydney hospital after he was hit on the side of the neck by a bouncer bowled by Sean Abbott during a Sheffield Shield game. [29] The same week, Hillel Oscar, an umpire and former captain of Israel's national cricket team, died after being hit in the neck by a ball. [30]

On 14 August 2017, Zubair Ahmed died after being hit on the head while batting in a club match played in the Mardan District, Khyber Pakhtunkhwa, Pakistan. [31]

Alternatives to cricket balls

A yellow alternative cricket ball Ball 3.JPG
A yellow alternative cricket ball

Sometimes alternatives to a real cricket ball may be preferred for reasons of safety, availability and cost. Examples include a tennis ball and a plastic version of the cricket ball.

Many casual players use a tennis ball wrapped in layers of some type of adhesive tape (often electrical tape), which makes the relatively soft tennis ball harder and smoother. This is commonly referred to as a tape ball. A common variant is to tape only half the tennis ball, to provide two different sides and make it easy to bowl with prodigious amounts of swing.

Younger players often use either tennis balls or an air-filled plastic 'windball' for safety reasons before using the 'hard' cricket ball after a certain age: windball cricket is also a popular sport in its own right. They might also use an 'IncrediBall' or an 'Aeroball' whilst making the step between windballs and 'hard' cricket balls. These balls are designed to mimic the feel, speed and bounce of a regular hard ball, but soften when coming in contact with objects at high speed, reducing the risk of injury.

<span class="mw-page-title-main">Bowling (cricket)</span> Cricket delivery

Bowling, in cricket, is the action of propelling the ball toward the wicket defended by a batter. A player skilled at bowling is called a bowler; a bowler who is also a competent batter is known as an all-rounder. Bowling the ball is distinguished from throwing the ball by a strictly specified biomechanical definition, which restricts the angle of extension of the elbow. A single act of bowling the ball towards the batsman is called a ball or a delivery. Bowlers bowl deliveries in sets of six, called an over. Once a bowler has bowled an over, a teammate will bowl an over from the other end of the pitch. The Laws of Cricket govern how a ball must be bowled. If a ball is bowled illegally, an umpire will rule it a no-ball. If a ball is bowled too wide of the striker for the batsman to be able to play at it with a proper cricket shot, the bowler's end umpire will rule it a wide.

In cricket, an umpire is a person who has the authority to make decisions about events on the cricket field according to the Laws of Cricket. Besides making decisions about legality of delivery, appeals for wickets and general conduct of the Game in a legal manner, the umpire also keeps a record of the deliveries and announces the completion of an over.

<span class="mw-page-title-main">Backyard cricket</span> Informal variations of cricket played outside of organized leagues

Backyard cricket, also known as bat ball, street cricket, beach cricket, corridor cricket, garden cricket, gully cricket and box cricket, is an informal variant of cricket. It is typically played in various non-traditional venues such as gardens, backyards, streets, parks, carparks, beaches, and any area not specifically designed for the sport.

The Laws of Cricket is a code that specifies the rules of the game of cricket worldwide. The earliest known code was drafted in 1744. Since 1788, the code has been owned and maintained by the private Marylebone Cricket Club (MCC) in Lord's Cricket Ground, London. There are currently 42 Laws, which describe all aspects of how the game is to be played. MCC has re-coded the Laws six times, each with interim revisions that produce more than one edition. The most recent code, the seventh, was released in October 2017; its 3rd edition came into force on 1 October 2022.

A cricket pitch consists of the central strip of a cricket field between the two wickets. It is 22 yd (20.12 m) long and 10 ft (3.05 m) wide. The surface is flat and is normally covered with extremely short grass, but can be completely dry or dusty soil with barely any grass or, in some circumstances, made from an artificial material. Over the course of a cricket match, the pitch is not repaired or altered other than in special circumstances - meaning that it will change condition. Any grass on the pitch in the game's first over, for example, may have disappeared by the twentieth over due to wear.

This is a general glossary of the terminology used in the sport of cricket. Where words in a sentence are also defined elsewhere in this article, they appear in italics. Certain aspects of cricket terminology are explained in more detail in cricket statistics and the naming of fielding positions is explained at fielding (cricket).

In the sport of cricket, a bouncer is a type of short-pitched delivery, usually bowled by a fast bowler, which bounces once and then reaches the batter at head-height.

Fast bowling is a type of bowling in cricket, in which the ball is delivered at high speed. The fastest bowlers bowl the ball at over 90mph. In addition to delivering the ball at speed, fast bowlers may also use seam bowling or swing bowling techniques, to make it even harder for the batter to play the ball correctly.

Seam bowling is a bowling technique in cricket, whereby the ball is deliberately bowled to hit the ground on its seam, to cause a random deviation when it bounces. A bowler who uses this technique is called a seam bowler or seamer.

<span class="mw-page-title-main">Extra (cricket)</span> Cricket term

In cricket, an extra is a run scored by, or awarded to, a batting team which is not credited to any individual batter. They are the runs scored by methods other than striking the ball with the bat.

<span class="mw-page-title-main">Dismissal (cricket)</span> Cricket terminology

In cricket, a dismissal occurs when a batter's innings is brought to an end by the opposing team. Other terms used are the batter being out, the batting side losing a wicket, and the fielding side taking a wicket. The ball becomes dead, and the dismissed batter must leave the field of play for the rest of their team's innings, to be replaced by a team-mate. A team's innings ends if ten of the eleven team members are dismissed. Players bat in pairs so, when only one batter remains who can be not out, it is not possible for the team to bat any longer. This is known as dismissing or bowling out the batting team, who are said to be all out.

Baseball and cricket are the best-known members of a family of related bat-and-ball games. Both have fields that are 400 feet (120 m) or more in diameter between their furthest endpoints, offensive players who can hit a thrown/"bowled" ball out of the field and run between safe areas to score runs (points) at the risk of being gotten out, and have a major game format lasting about 3 hours.

<span class="mw-page-title-main">Delivery (cricket)</span> Single action of bowling a cricket ball

A delivery or ball in cricket is a single action of bowling a cricket ball toward the batter. Once the ball has been delivered, batters may attempt to score runs, with the bowler and other fielders attempting to stop this by getting the batters out.

Two players from the batting team, the striker and nonstriker, stand in front of either wicket holding bats, while one player from the fielding team, the bowler, bowls the ball toward the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball with the bat and then switch places with the nonstriker, with the batting team scoring one run for each of these exchanges.
