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 batsman 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.

. 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. 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 "

, 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. 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.

Colour

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. 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: 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, 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 batsmen to sight the ball after 30–40 overs of use. 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. 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, so the pink ball was designed to provide a satisfactory compromise on both 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. 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, 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.

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, at least two new balls are used for each match. 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 – 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. 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. Cricket balls can be bowled at close to 160 km/h (100 mph) 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 then other methods. As cricket bats have become thicker, the ball can now be hit well over 100 metres before touching the ground. Cricket commentator and former Test bowler

Condition of a 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'': * If the ball becomes damaged or lost. * If the condition of the ball is illegally modified by a player. * In Test cricket, after the ball currently in use becomes 80 overs old, the captain of the bowling side has the option to take a new ball. 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 apply saliva or sweat to the ball as they polish it. The practice of applying saliva has been banned by the ICC during the ongoing

. 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". 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: * rub any substance apart from saliva or sweat onto the ball * rub the ball on the ground * scuff the ball with any rough object, including the fingernails * pick at or lift the seam of the ball. * apply saliva on the ball (ongoing due to the

at the highest levels of cricket. 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 batsmen and close fielders often wear protective equipment. Cricket ball injuries are fairly frequent, including eye (with some players having lost eyes), head and face, finger and toe, teeth and testicular injuries. 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. The Indian batsman Nariman 'Nari' Contractor had to retire from the game after being hit on the head by a ball in the West Indies in 1962. In 1998, Indian cricketer

Alternatives to cricket balls

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

. 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.
