Adeliveryorballincricketis a single action ofbowlingacricket balltoward thebatter.Once the ball has been delivered, batters may attempt to scoreruns,with the bowler and otherfieldersattempting to stop this by getting the battersout.When the ball becomesdead,the next delivery can begin.

During the play of the game, a member of the fielding team is designated as thebowlerand bowls deliveries toward the batter. Six legal balls in a row constitutes anover,after which a different member of thefieldingside takes over the role of bowler for the next over. The bowler delivers the ball from their end of thepitchtoward the batter standing at the oppositewicketat the other end of thepitch.Bowlers can be either left-handed or right-handed. This approach to their delivery, in addition to their decision of bowlingaround the wicket(from the sides of the wicket on the bowler's end) orover the wicket,is knowledge of which the umpire and the batter are to be made aware.

Some formsof cricket limit the number of legal deliveries that may be bowled in eachinnings;for example,100-ball crickethas a maximum of 200 legal deliveries in the game (unless there is a tie). Every delivery in a cricket match is notated by the number of completed overs that have occurred before that delivery, as well as which delivery in the current over that delivery is; for example, "Over 14.2" indicates that 14 overs have been completed and the second delivery of the 15th over is the one under consideration. Since illegal deliveries do not count towards the progression of an over, a set of consecutive illegal deliveries (and the legal delivery that follows them) will have the same notation.Illegal deliveriesgenerally occur when a bowler bowls from too close to the batter, or delivers the ball out of the batter's reach.

Legal and illegal deliveries

Main article:Illegal delivery (cricket)

All deliveries are either legal (also known as fair, valid, or "one of the over" ), illegal, or in rare circumstances, calleddeadand invalidated.

Illegal deliveries

An illegal delivery always results in the batting team being awarded one run in addition to any other runs scored off the illegal delivery, does not count towards the completion of an over, and is divided into two categories:widesandno-balls.No-balls are considered a more serious infraction than wides, with the batters being shielded from most methods ofdismissal,and in some competitions result in the batting team being awarded two additional runs and/or a "free hit"on the next legal delivery (on a free hit delivery, the batters have the same protections against being dismissed as on a no-ball).

Wides

A delivery is called wide if it is so far out of reach of the striker that it can not be hit by the striker through the use of a normal cricket stroke. Note however that a delivery may not be called a wide if the striker changes their positioning before the ball is bowled in such a way that they bring the ball within their reach.

No-balls

A delivery can be called a no-ball for various reasons, which may pertain either to the actions of the bowler or the other players on the fielding team. The most common reasons a no-ball occurs are because the bowler either fails to keep some part of his front foot behind thepopping creasewhen bowling the ball, or bowls the ball and it reaches the striker above the waist without having bounced before reaching the striker.

Types of delivery

Deliveries can be made byfast bowlersor byspin bowlers.Fast bowlers tend to make the ball either move off the pitch (‘seam’) or move through the air (’swing’), while spinners make the ball ’turn’ either toward a right-handed batter (as in the case ofoff spinandleft-arm unorthodox spin) or away from him (as in the case ofleg spinandleft-arm orthodox spin).

The ball can bounce at different distances from the batter, this is called thelengthof the delivery. It can range from abouncer(often bouncing as high as the batter's head) to ayorker(landing at his feet).

There are many different types of delivery that a bowler can bowl. These deliveries vary by: technique, the hand the bowler bowls with, use of the fingers, use of the seam, how the ball is positioned in the hand, where the ball is pitched on the wicket, the speed of the ball, and the tactical intent of the bowler.

Tactical considerations

The variations in different types of delivery, as well as variations caused by directing the ball with differingline and length,are key weapons in a bowler's arsenal. Throughout an over, the bowler will choose a sequence of deliveries designed to attack the batter's concentration and technique, in an effort to get himout.

The bowler also varies the amount ofloopandpaceimparted to various deliveries to try to cause the batter to misjudge and make a mistake. As thecreasehas a width, the bowler can change the angle from which he delivers to the batter in an attempt to induce a misjudgement.

Usually, the bowler decides what type of delivery to bowl next, without consultation or even informing any other member of his team. Sometimes, the teamcaptainwill offer advice or even issue a direct order regarding what deliveries to bowl, based on his observations of the batter and the strategic state of the game. Another player who occasionally offers advice to the bowler is thewicket-keeper,since he has a unique view of the batter and may be able to spot weaknesses of technique.

Another piece of information important for the bowlers to consider prior to their deliveries is the state of pitch. The pitch is a natural ground and its state is subjected to variation over the course of the cricket, some of which are multi-day events such as test matches. Spinners find an old pitch, one that has been frequently used, more suitable to their deliveries rather than a fresh pitch, one that has not come under use as much such as a pitch at the start of the match.

The batter's anticipation of the delivery

While a bowler, with the use of variations in their delivery aims to target the concentration of batters as well as their skill and technique of batting, anticipation of the delivery is crucial for the batter, as emphasised by Jodi Richardson.Richardson reveals the world class batter's dilemma while facing fast bowlers, stating that the time between the batters' anticipation of the trajectory of the ball and positioning themselves for the appropriate shot can be twice as long as the interval between the ball leaving the bowler's hand and reaching the batter's crease. Side by side, Richardson alludes to the research undertaken by Dr. Sean Müller in Australia which was partly funded byCricket Australia'sCentre of Excellence.The results of the research demonstrated the importance of anticipation of the delivery for batters in cricket. They revealed that experienced batters possessed a unique ability which enabled them to adjust their feet as well as their positioning on the crease accordingly based upon their reading of the body language and movements enacted by the bowler prior to the release of the ball. This foresight that batters use while on the crease is referred to as 'advance information' by Richardson. Moreover, Müller's research outlined that the presence of this 'advance information' was not as evident among the lesser skilled batters in comparison to the experienced ones.

Controversies and debate involving deliveries

Underarm bowling

Main article:Underarm bowling incident of 1981

Underarm orlob bowlingwas the original cricket delivery style, but had largely died out before the 20th century, although it was used until 1910 byGeorge Simpson-Hayward,and remained a legal delivery type. On 1 February 1981, whenAustraliawas playingNew Zealandin aOne Day Internationalcricketmatch, and New Zealand needed six runs to tie the match from the final ball.Greg Chappell,the Australian captain, ordered the bowler (his brotherTrevor) to bowlunderarm,rolling the ball along the ground to prevent the Number 10 New Zealand batter (Brian McKechnie) any chance of hitting asixfrom the last ball to tie the match.

After the game, the thenPrime Minister of New Zealand,Rob Muldoon,described it as "the most disgusting incident I can recall in the history of cricket."At the time, underarm deliveries were legal, but as a direct result of the incident, underarm bowling was banned in limited overs cricket by theInternational Cricket Councilas "not within the spirit of the game." The 2000Laws of Cricketdeclares that an underarm delivery is illegalunless otherwise agreed before the match.

Suspect bowling actions

A recently retired cricketer who was greatly embroiled in controversy and under scrutiny from critics over his method of executing deliveries was the Sri Lankan spinnerMuttiah Muralitharan.Michael Selvey describes the accusations placed on the bowler in relation to his widely disputed bowling action and delivery, stating the Australian prime minister's reference to the Sri Lankan as a 'chucker.' The controversy linked to Muralitharan's delivery emerged in 1995, when the umpire of the test match between Sri Lanka and Australia deemed Muralitharan's delivery as illegal on the suspicion that he was throwing the ball. Selvey acknowledges this as the factor sparking an 'international cricket incident,' with critics and some extremists going as far as insisting on the exclusion of all of the Sri Lankan's accomplishments throughout his career from the records of cricket. However,Suresh Menontakes an adamant stance on the topic of the controversy surrounding the spinner by displaying appreciation for Muralitharan's actions. Menon suggests that investigation into Muralitharan's deliveries led to the revelation of imperfections present in the bowling action and deliveries of the previously considered 'picture-perfect' fast bowler,Glenn McGrath.This was made possible with the usage of technology and its replacement of the earlier system, which Menon refers to as 'the naked eye.' Eventually, it was declared legal for the bowlers to bend their arm fifteen degrees for deliveries in cricket.
