In cricket, a player's bowling average is the number of runs they have conceded per wicket taken. The lower the bowling average is, the better the bowler is performing, it is one of a number of statistics used to compare bowlers used alongside the economy rate and the strike rate to judge the overall performance of a bowler. When a bowler has taken only a small number of wickets, their bowling average can be artificially high or low, unstable, with further wickets taken or runs conceded resulting in large changes to their bowling average. Due to this, qualification restrictions are applied when determining which players have the best bowling averages. After applying these criteria, George Lohmann holds the record for the lowest average in Test cricket, having claimed 112 wickets at an average of 10.75 runs per wicket. A cricketer's bowling average is calculated by dividing the numbers of runs they have conceded by the number of wickets they have taken; the number of runs conceded by a bowler is determined as the total number of runs that the opposing side have scored while the bowler was bowling, excluding any byes, leg byes, or penalty runs.
The bowler receives credit for any wickets taken during their bowling that are either bowled, hit wicket, leg before wicket or stumped. B o w l i n g a v e r a g e = R u n s c o n c e d e d W i c k e t s t a k e n A number of flaws have been identified for the statistic, most notable among these the fact that a bowler who has taken no wickets can not have a bowling average, as dividing by zero does not give a result; the effect of this is that the bowling average can not distinguish between a bowler who has taken no wickets and conceded one run, a bowler who has taken no wickets and conceded one hundred runs. The bowling average does not tend to give a true reflection of the bowler's ability when the number of wickets they have taken is small in comparison to the number of runs they have conceded. In his paper proposing an alternative method of judging batsmen and bowlers, Paul van Staden gives an example of this: Suppose a bowler has bowled a total of 80 balls, conceded 60 runs and has taken only 2 wickets so that..
30. If the bowler takes a wicket with the next ball bowled 20. Due to this, when establishing records for bowling averages, qualification criteria are set. For Test cricket, the Wisden Cricketers' Almanack sets this as 75 wickets, while ESPNcricinfo requires 2,000 deliveries. Similar restrictions are set for one-day cricket. A number of factors other than purely the ability level of the bowler have an effect on a player's bowling average. Most significant among these are the different eras; the bowling average tables in Test and first-class cricket are headed by players who competed in the nineteenth century, a period when pitches were uncovered and some were so badly looked after that they had rocks on them. The bowlers competing in the Howa Bowl, a competition played in South African during the apartheid-era, restricted to non-white players, during which time, according to Vincent Barnes: "Most of the wickets we played on were underprepared. For me, as a bowler, it was great." Other factors which provided an advantage to bowlers in that era was the lack of significant safety equipment.
Other variations are caused by frequent matches against stronger or weaker opposition, changes in the laws of cricket and the length of matches. Due to the varying qualifying restrictions placed on the records by different statisticians, the record for the lowest career bowling average can be different from publication to publication. In Test cricket, George Lohmann is listed as having the superior average by each of the Wisden Cricketers' Almanack, ESPNcricinfo and CricketArchive. Though all three use different restrictions, Lohmann's average of 10.75 is considered the best. If no qualification criteria were applied at all, three players—Wilf Barber, A. N. Hornby and Bruce Murray—would tie for the best average, all having claimed just one wicket in Test matches, without conceding any runs, thus averaging zero. ESPNcricinfo list Betty Wilson as having the best Women's Test cricket average with 11.80, while CricketArchive accept Mary Spear's average of 5.78. In One Day Internationals, the varying criteria set by ESPNcricinfo and CricketArchive result in different players being listed as holding the record.
ESPNcricinfo has the stricter restriction, requiring 1,000 deliveries: by this measure, Joel Garner is the record-holder, having claimed his wickets at an average of 18.84. By CricketArchive's more relaxed requirement of 400 deliveries, John Snow leads the way, with an average of 16.57. In women's One Day International cricket, Caroline Barrs tops the CricketArchive list with an average of 9.52, but by ESPNcricinfo's stricter guidelines, the record is instead held by Gill Smith's 12.53. The record is again split for the two websites for Twenty20 International cricket. George O'Brien's average of 8.20 holds the record using those criteri
Fast bowling is one of two main approaches to bowling in the sport of cricket, the other being spin bowling. Practitioners of pace bowling are known as fast bowlers, quicks, or pacemen, they can be referred to as a seam bowler or a'fast bowler who can swing it' to reflect the predominant characteristic of their deliveries. Speaking, a pure swing bowler does not need to have a high degree of pace, though dedicated medium-pace swing bowlers are seen at Test level these days; the aim of fast bowling is to deliver the ball in such a fashion as to cause the batsman to make a mistake. The bowler achieves this by making the hard cricket ball deviate from a predictable, linear trajectory at a speed that limits the time the batsman has to compensate for it. For deviation caused by the ball's stitching, the ball bounces off the pitch and deflects either away from the batsman's body, or inwards towards them. Swing bowlers on the other hand use the seam of the ball but in a different way. To'bowl swing' is to induce a curved trajectory of the cricket ball through the air.
Swing bowlers use a combination of seam orientation, body position at the point of release, asymmetric ball polishing, variations in delivery speed to affect an aerodynamic influence on the ball. The ability of a bowler to induce lateral deviation or'sideways movement' make it difficult for the batsman to address the flight of the ball accurately. Beyond this ability to create an unpredictable path of ball trajectory, the fastest bowlers can be potent by delivering a ball at such a rate that a batsman fails to react either or at all. A typical fast delivery has a speed in the range of 137–153 km/h, it is possible for a bowler to concentrate on speed when young, but as fast bowlers mature they pick up new skills and tend to rely more on swing bowling or seam bowling techniques. Most fast bowlers specialise in one of these two areas and are sometimes categorised as swing or seam bowler. However, this classification is not satisfactory because the categories are not mutually exclusive and a skilled bowler bowls a mixture of fast, swinging and cutting balls—even if he prefers one style to the others.
For simplicity, it is common to subdivide fast bowlers according to the average speed of their deliveries, as follows. There is a degree of subjectivity in the usage of these terms. For comparison, most spin bowlers in professional cricket bowl at average speeds of 70 to 90 km/h. Shoaib Akhtar, Brett Lee, Shaun Tait, Jeff Thomson and Mitchell Starc have clocked over 160 km/h and are categorised as "Ultra Fast" bowlers although bowling at speeds lower than this mark. While Steven Finn is classified as a fast-medium bowler by Cricinfo, he can bowl at around 145 km/h, with his fastest clocked at 151.9 km/h, making him the 10th fastest amongst active bowlers as of 3 January 2015 The first thing a fast bowler needs to do is to grip the ball correctly. The basic fast bowling grip to achieve maximum speed is to hold the ball with the seam upright and to place the index and middle fingers close together at the top of the seam with the thumb gripping the ball at the bottom of the seam; the image to the right shows the correct grip.
The first two fingers and the thumb should hold the ball forward of the rest of the hand, the other two fingers should be tucked into the palm. The ball is held quite loosely so. Other grips are possible, result in different balls – see swing and seam bowling below; the bowler holds their other hand over the hand gripping the ball until the latest possible moment so that the batsman cannot see what type of ball is being bowled. A fast bowler needs to take a longer run-up toward the wicket than a spinner, due to the need to generate the momentum and rhythm required to bowl a fast delivery. Fast bowlers measure their preferred run up in strides, mark the distance from the wicket, it is important for the bowler to know how long the run-up is because it must terminate behind the popping crease. A bowler who steps on or beyond this has bowled a no-ball, which affords the batsman immunity from dismissal, adds one run to the batting team's score, forces the bowler to bowl another ball in the over. At the end of the run-up the bowler brings his lead foot down on the pitch with the knee as straight as possible.
This can be dangerous due to the pressure it places on the joint. Knee injuries are not uncommon amongst fast bowlers: for example, the English pace bowler David Lawrence was sidelined for many months after splitting his kneecap in two; the pressure on the leading foot is such that some fast bowlers cut the front off their shoes to stop their toes from being injured as they are pressed against the inside of the shoe. The bowler brings the bowling arm up over their head and releases the ball at the height appropriate to where they want the ball to pitch. Again, the arm must be straight though this is a stipulation of the laws of cricket rather than an aid to speed. Bending the elbow and "chucking" the ball would make it too easy for the bowler to aim at the batsman's wicket and get them out. Fast bowlers tend to have an action that leaves them either side-on or chest-on at the end of the run up. A chest-on bowler has chest and hips aligned towards the batsman at the instant of back foot contact, while a side-on bowler has chest and hips aligned at ninety degrees to the batsman at the instant of back foot contact.
West Indian bowler Malcolm Marshall was a c
Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of, a 20-metre pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by striking the ball bowled at the wicket with the bat, while the bowling and fielding side tries to prevent this and dismiss each player. Means of dismissal include being bowled, when the ball hits the stumps and dislodges the bails, by the fielding side catching the ball after it is hit by the bat, but before it hits the ground; when ten players have been dismissed, the innings ends and the teams swap roles. The game is adjudicated by two umpires, aided by a third umpire and match referee in international matches, they communicate with two off-field scorers. There are various formats ranging from Twenty20, played over a few hours with each team batting for a single innings of 20 overs, to Test matches, played over five days with unlimited overs and the teams each batting for two innings of unlimited length.
Traditionally cricketers play in all-white kit, but in limited overs cricket they wear club or team colours. In addition to the basic kit, some players wear protective gear to prevent injury caused by the ball, a hard, solid spheroid made of compressed leather with a raised sewn seam enclosing a cork core, layered with wound string. Cricket's origins are uncertain and the earliest definite reference is in south-east England in the middle of the 16th century, it spread globally with the expansion of the British Empire, leading to the first international matches in the second half of the 19th century. The game's governing body is the International Cricket Council, which has over 100 members, twelve of which are full members who play Test matches; the game's rules are held in a code called the Laws of Cricket, owned and maintained by Marylebone Cricket Club in London. The sport is followed in the Indian subcontinent, the United Kingdom, southern Africa and the West Indies, its globalisation occurring during the expansion of the British Empire and remaining popular into the 21st century.
Women's cricket, organised and played separately, has achieved international standard. The most successful side playing international cricket is Australia, having won seven One Day International trophies, including five World Cups, more than any other country, having been the top-rated Test side more than any other country. Cricket is one of many games in the "club ball" sphere that involve hitting a ball with a hand-held implement. In cricket's case, a key difference is the existence of a solid target structure, the wicket, that the batsman must defend; the cricket historian Harry Altham identified three "groups" of "club ball" games: the "hockey group", in which the ball is driven to and fro between two targets. It is believed that cricket originated as a children's game in the south-eastern counties of England, sometime during the medieval period. Although there are claims for prior dates, the earliest definite reference to cricket being played comes from evidence given at a court case in Guildford on Monday, 17 January 1597.
The case concerned ownership of a certain plot of land and the court heard the testimony of a 59-year-old coroner, John Derrick, who gave witness that: "Being a scholler in the ffree schoole of Guldeford hee and diverse of his fellows did runne and play there at creckett and other plaies". Given Derrick's age, it was about half a century earlier when he was at school and so it is certain that cricket was being played c. 1550 by boys in Surrey. The view that it was a children's game is reinforced by Randle Cotgrave's 1611 English-French dictionary in which he defined the noun "crosse" as "the crooked staff wherewith boys play at cricket" and the verb form "crosser" as "to play at cricket". One possible source for the sport's name is the Old English word "cryce" meaning a staff. In Samuel Johnson's Dictionary, he derived cricket from "cryce, Saxon, a stick". In Old French, the word "criquet" seems to have meant a kind of stick. Given the strong medieval trade connections between south-east England and the County of Flanders when the latter belonged to the Duchy of Burgundy, the name may have been derived from the Middle Dutch "krick", meaning a stick.
Another possible source is the Middle Dutch word "krickstoel", meaning a long low stool used for kneeling in church and which resembled the long low wicket with two stumps used in early cricket. According to Heiner Gillmeister, a European language expert of Bonn University, "cricket" derives from the Middle Dutch phrase for hockey, met de sen. Gillmeister has suggested that not only the name but the sport itself may be of Flemish origin. Although the main object of the game has always been to score the most runs, the early form of cricket differed from the modern game in certain key technical aspects; the ball was bowled underarm by the bowler and all along the ground towards a batsman armed with a bat that, in shape, resembled a hockey stick.
South Africa the Republic of South Africa, is the southernmost country in Africa. It is bounded to the south by 2,798 kilometres of coastline of Southern Africa stretching along the South Atlantic and Indian Oceans. South Africa is the largest country in Southern Africa and the 25th-largest country in the world by land area and, with over 57 million people, is the world's 24th-most populous nation, it is the southernmost country on the mainland of the Eastern Hemisphere. About 80 percent of South Africans are of Sub-Saharan African ancestry, divided among a variety of ethnic groups speaking different African languages, nine of which have official status; the remaining population consists of Africa's largest communities of European and multiracial ancestry. South Africa is a multiethnic society encompassing a wide variety of cultures and religions, its pluralistic makeup is reflected in the constitution's recognition of 11 official languages, the fourth highest number in the world. Two of these languages are of European origin: Afrikaans developed from Dutch and serves as the first language of most coloured and white South Africans.
The country is one of the few in Africa never to have had a coup d'état, regular elections have been held for a century. However, the vast majority of black South Africans were not enfranchised until 1994. During the 20th century, the black majority sought to recover its rights from the dominant white minority, with this struggle playing a large role in the country's recent history and politics; the National Party imposed apartheid in 1948. After a long and sometimes violent struggle by the African National Congress and other anti-apartheid activists both inside and outside the country, the repeal of discriminatory laws began in 1990. Since 1994, all ethnic and linguistic groups have held political representation in the country's liberal democracy, which comprises a parliamentary republic and nine provinces. South Africa is referred to as the "rainbow nation" to describe the country's multicultural diversity in the wake of apartheid; the World Bank classifies South Africa as an upper-middle-income economy, a newly industrialised country.
Its economy is the second-largest in Africa, the 34th-largest in the world. In terms of purchasing power parity, South Africa has the seventh-highest per capita income in Africa; however and inequality remain widespread, with about a quarter of the population unemployed and living on less than US$1.25 a day. South Africa has been identified as a middle power in international affairs, maintains significant regional influence; the name "South Africa" is derived from the country's geographic location at the southern tip of Africa. Upon formation, the country was named the Union of South Africa in English, reflecting its origin from the unification of four separate British colonies. Since 1961, the long form name in English has been the "Republic of South Africa". In Dutch, the country was named Republiek van Zuid-Afrika, replaced in 1983 by the Afrikaans Republiek van Suid-Afrika. Since 1994, the Republic has had an official name in each of its 11 official languages. Mzansi, derived from the Xhosa noun umzantsi meaning "south", is a colloquial name for South Africa, while some Pan-Africanist political parties prefer the term "Azania".
South Africa contains human-fossil sites in the world. Archaeologists have recovered extensive fossil remains from a series of caves in Gauteng Province; the area, a UNESCO World Heritage site, has been branded "the Cradle of Humankind". The sites include one of the richest sites for hominin fossils in the world. Other sites include Gondolin Cave Kromdraai, Coopers Cave and Malapa. Raymond Dart identified the first hominin fossil discovered in Africa, the Taung Child in 1924. Further hominin remains have come from the sites of Makapansgat in Limpopo Province and Florisbad in the Free State Province, Border Cave in KwaZulu-Natal Province, Klasies River Mouth in Eastern Cape Province and Pinnacle Point and Die Kelders Cave in Western Cape Province; these finds suggest that various hominid species existed in South Africa from about three million years ago, starting with Australopithecus africanus. There followed species including Australopithecus sediba, Homo ergaster, Homo erectus, Homo rhodesiensis, Homo helmei, Homo naledi and modern humans.
Modern humans have inhabited Southern Africa for at least 170,000 years. Various researchers have located pebble tools within the Vaal River valley. Settlements of Bantu-speaking peoples, who were iron-using agriculturists and herdsmen, were present south of the Limpopo River by the 4th or 5th century CE, they displaced and absorbed the original Khoisan speakers, the Khoikhoi and San peoples. The Bantu moved south; the earliest ironworks in modern-day KwaZulu-Natal Province are believed to date from around 1050. The southernmost group was the Xhosa people, whose language incorporates certain linguistic traits from the earlier Khoisan people; the Xhosa reached the Great Fish River, in today's Eastern Cape Province. As they migrated, these larger Iron Age populations
Quebec is one of the thirteen provinces and territories of Canada. It is bordered to the west by the province of Ontario and the bodies of water James Bay and Hudson Bay. S. states of Maine, New Hampshire and New York. It shares maritime borders with Nunavut, Prince Edward Island, Nova Scotia. Quebec is Canada's largest province by its second-largest administrative division, it is and politically considered to be part of Central Canada. Quebec is the second-most populous province of Canada, after Ontario, it is the only one to have a predominantly French-speaking population, with French as the sole provincial official language. Most inhabitants live in urban areas near the Saint Lawrence River between Montreal and Quebec City, the capital. Half of Quebec residents live in the Greater Montreal Area, including the Island of Montreal. English-speaking communities and English-language institutions are concentrated in the west of the island of Montreal but are significantly present in the Outaouais, Eastern Townships, Gaspé regions.
The Nord-du-Québec region, occupying the northern half of the province, is sparsely populated and inhabited by Aboriginal peoples. The climate around the major cities is four-seasons continental with cold and snowy winters combined with warm to hot humid summers, but farther north long winter seasons dominate and as a result the northern areas of the province are marked by tundra conditions. In central Quebec, at comparatively southerly latitudes, winters are severe in inland areas. Quebec independence debates have played a large role in the politics of the province. Parti Québécois governments held referendums on sovereignty in 1980 and 1995. Although neither passed, the 1995 referendum saw the highest voter turnout in Quebec history, at over 93%, only failed by less than 1%. In 2006, the House of Commons of Canada passed a symbolic motion recognizing the "Québécois as a nation within a united Canada". While the province's substantial natural resources have long been the mainstay of its economy, sectors of the knowledge economy such as aerospace and communication technologies and the pharmaceutical industry play leading roles.
These many industries have all contributed to helping Quebec become an economically influential province within Canada, second only to Ontario in economic output. The name "Québec", which comes from the Algonquin word kébec meaning "where the river narrows" referred to the area around Quebec City where the Saint Lawrence River narrows to a cliff-lined gap. Early variations in the spelling of the name included Kébec. French explorer Samuel de Champlain chose the name Québec in 1608 for the colonial outpost he would use as the administrative seat for the French colony of New France; the province is sometimes referred to as "La belle province". The Province of Quebec was founded in the Royal Proclamation of 1763 after the Treaty of Paris formally transferred the French colony of Canada to Britain after the Seven Years' War; the proclamation restricted the province to an area along the banks of the Saint Lawrence River. The Quebec Act of 1774 expanded the territory of the province to include the Great Lakes and the Ohio River Valley and south of Rupert's Land, more or less restoring the borders existing under French rule before the Conquest of 1760.
The Treaty of Paris ceded territories south of the Great Lakes to the United States. After the Constitutional Act of 1791, the territory was divided between Lower Canada and Upper Canada, with each being granted an elected legislative assembly. In 1840, these become Canada East and Canada West after the British Parliament unified Upper and Lower Canada into the Province of Canada; this territory was redivided into the Provinces of Quebec and Ontario at Confederation in 1867. Each became one of the first four provinces. In 1870, Canada purchased Rupert's Land from the Hudson's Bay Company and over the next few decades the Parliament of Canada transferred to Quebec portions of this territory that would more than triple the size of the province. In 1898, the Canadian Parliament passed the first Quebec Boundary Extension Act that expanded the provincial boundaries northward to include the lands of the local aboriginal peoples; this was followed by the addition of the District of Ungava through the Quebec Boundaries Extension Act of 1912 that added the northernmost lands of the Inuit to create the modern Province of Quebec.
In 1927, the border between Quebec and Newfoundland and Labrador was established by the British Judicial Committee of the Privy Council. Quebec disputes this boundary. Located in the eastern part of Canada, part of Central Canada, Quebec occupies a territory nearly three times the size of France or Texas, most of, sparsely populated, its topography is different from one region to another due to the varying composition of the ground, the climate, the proximity to water. The Saint Lawrence Lowland and the Appalachians are the two main topographic regions in southern Quebec, while the Canadian Shield occupies most of central and northern Quebec. Quebec has one of the world's largest reserves of fresh water, occupying 12% of its surface, it has 3 % of the world's renewable fresh water. Mor
Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border, its capital is Ottawa, its three largest metropolitan areas are Toronto and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra, its population is urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons. Various indigenous peoples have inhabited what is now Canada for thousands of years prior to European colonization. Beginning in the 16th century and French expeditions explored, settled, along the Atlantic coast.
As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces; this began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster of 1931 and culminated in the Canada Act of 1982, which severed the vestiges of legal dependence on the British parliament. Canada is a parliamentary democracy and a constitutional monarchy in the Westminster tradition, with Elizabeth II as its queen and a prime minister who serves as the chair of the federal cabinet and head of government; the country is a realm within the Commonwealth of Nations, a member of the Francophonie and bilingual at the federal level. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, education.
It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Canada's long and complex relationship with the United States has had a significant impact on its economy and culture. A developed country, Canada has the sixteenth-highest nominal per capita income globally as well as the twelfth-highest ranking in the Human Development Index, its advanced economy is the tenth-largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks. Canada is part of several major international and intergovernmental institutions or groupings including the United Nations, the North Atlantic Treaty Organization, the G7, the Group of Ten, the G20, the North American Free Trade Agreement and the Asia-Pacific Economic Cooperation forum. While a variety of theories have been postulated for the etymological origins of Canada, the name is now accepted as coming from the St. Lawrence Iroquoian word kanata, meaning "village" or "settlement".
In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona. Cartier used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona. From the 16th to the early 18th century "Canada" referred to the part of New France that lay along the Saint Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named the Canadas. Upon Confederation in 1867, Canada was adopted as the legal name for the new country at the London Conference, the word Dominion was conferred as the country's title. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "Realm of the Commonwealth"; the government of Louis St. Laurent ended the practice of using'Dominion' in the Statutes of Canada in 1951. In 1982, the passage of the Canada Act, bringing the Constitution of Canada under Canadian control, referred only to Canada, that year the name of the national holiday was changed from Dominion Day to Canada Day.
The term Dominion was used to distinguish the federal government from the provinces, though after the Second World War the term federal had replaced dominion. Indigenous peoples in present-day Canada include the First Nations, Métis, the last being a mixed-blood people who originated in the mid-17th century when First Nations and Inuit people married European settlers; the term "Aboriginal" as a collective noun is a specific term of art used in some legal documents, including the Constitution Act 1982. The first inhabitants of North America are hypothesized to have migrated from Siberia by way of the Bering land bridge and arrived at least 14,000 years ago; the Paleo-Indian archeological sites at Old Crow Flats and Bluefish Caves are two of the oldest sites of human habitation in Canada. The characteristics of Canadian indigenous societies included permanent settlements, complex societal hierarchies, trading networks; some of these cultures had collapsed by the time European explorers arrived in the late 15th and early 16th centuries and have only been discovered through archeological investigations.
The indigenous population at the time of the first European settlements is estimated to have been between 200,000
A delivery or ball in cricket is a single action of bowling a cricket ball toward the batsman. During play of the game, a member of the fielding team is designated as the bowler, bowls deliveries toward the batsman. Six legal balls in a row constitutes an over, after which a different member of the fielding side takes over the role of bowler for the next over; the bowler delivers the ball from his or her end of the pitch toward the batsman standing at the opposite wicket at the other end of the pitch. Bowlers can be either right-handed; this approach to their delivery, in addition to their decision of bowling around the wicket or over the wicket, is knowledge of which the umpire and the batsman are to be made aware. Deliveries can be made by spin bowlers. Fast bowlers tend to make the ball either move off the pitch or move through the air, while spinners make the ball "turn" either toward a right-handed batsman or away from him; the ball can bounce at different distances from the batsman, this is called the length of the delivery.
It can range from a bouncer to a yorker. There are many different types of delivery; 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, the tactical intent of the bowler. Leg spin deliveries and mirror equivalents for left arm unorthodox spin: Leg break Googly Topspinner Flipper Slider Flicker ball Off spin deliveries and mirror equivalents for left arm orthodox spin: Off break Doosra Arm ball Topspinner Carrom ball Teesra Fast bowling deliveries: Bouncer Inswinger Reverse swing Leg cutter Off cutter Outswinger Yorker Beamer Knuckleball Slower ball The variations in different types of delivery, as well as variations caused by directing the ball with differing line 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 batsman's concentration and technique, in an effort to get him out.
The bowler varies the amount of loop and pace imparted to various deliveries to try to cause the batsman to misjudge and make a mistake. As the crease has a width, the bowler can change the angle from which he delivers to the batsman in an attempt to induce a misjudgement; the bowler decides what type of delivery to bowl next, without consultation or informing any other member of his team. Sometimes, the team captain will offer advice or issue a direct order regarding what deliveries to bowl, based on his observations of the batsman and the strategic state of the game. Another player who offers advice to the bowler is the wicket-keeper, since he has a unique view of the batsman 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, used, more suitable to their deliveries rather than a fresh pitch, one that hasn't come under use as much such as a pitch at the start of the match. While a bowler, with the use of variations in his/her delivery aims to target the concentration of batsmen as well as their skill and technique of batting, anticipation of the delivery is crucial for the batsman, as emphasised by Jodi Richardson. Richardson reveals the world class batsman's dilemma while facing fast bowlers, stating that the time between the batsmen's 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 batsman's crease. Side by side, Richardson alludes to the research undertaken by Dr. Sean Müller in Australia, funded by Cricket Australia's Centre of Excellence; the results of the research demonstrated the importance of anticipation of the delivery for batsmen in cricket.
They revealed that experienced batsmen 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 batsmen 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 batsmen in comparison to the experienced ones. Underarm or lob bowling was the original cricket delivery style,but had died out before the 20th century, although it was used until 1910 by George Simpson-Hayward, remained a legal delivery type. On 1 February 1981, when Australia was playing New Zealand in a One Day International cricket match, New Zealand needed six runs to tie the match from the final ball. Greg Chappell, the Australian captain, ordered the bowler to bowl underarm, rolling the ball along the ground to prevent the Number 10 New Zealand batsman any chance of hitting a six from the last ball to tie the match.
After the game, the Prime 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 limi
