Jamaica is an island country situated in the Caribbean Sea. Spanning 10,990 square kilometres in area, it is the third-largest island of the Greater Antilles and the fourth-largest island country in the Caribbean. Jamaica lies about 145 kilometres south of Cuba, 191 kilometres west of Hispaniola. Inhabited by the indigenous Arawak and Taíno peoples, the island came under Spanish rule following the arrival of Christopher Columbus in 1494. Many of the indigenous people died of disease, the Spanish transplanted African slaves to Jamaica as labourers; the island remained a possession of Spain until 1655, when England conquered it and renamed it Jamaica. Under British colonial rule Jamaica became a leading sugar exporter, with its plantation economy dependent on African slaves; the British emancipated all slaves in 1838, many freedmen chose to have subsistence farms rather than to work on plantations. Beginning in the 1840s, the British utilized Chinese and Indian indentured labour to work on plantations.
The island achieved independence from the United Kingdom on 6 August 1962. With 2.9 million people, Jamaica is the third-most populous Anglophone country in the Americas, the fourth-most populous country in the Caribbean. Kingston is the country's capital and largest city, with a population of 937,700. Jamaicans have African ancestry, with significant European, Indian and mixed-race minorities. Due to a high rate of emigration for work since the 1960s, Jamaica has a large diaspora in Canada, the United Kingdom, the United States. Jamaica is an upper-middle income country with an average of 4.3 million tourists a year. Jamaica is a Commonwealth realm, with Elizabeth II as its queen, her appointed representative in the country is the Governor-General of Jamaica, an office held by Sir Patrick Allen since 2009. Andrew Holness has served as Prime Minister of Jamaica since March 2016. Jamaica is a parliamentary constitutional monarchy with legislative power vested in the bicameral Parliament of Jamaica, consisting of an appointed Senate and a directly elected House of Representatives.
The indigenous people, the Taíno, called the island Xaymaca in Arawakan, meaning the "Land of Wood and Water" or the "Land of Springs". Colloquially Jamaicans refer to their home island as the "Rock." Slang names such as "Jamrock", "Jamdown", or "Ja", have derived from this. The Arawak and Taíno indigenous people, originating in South America, first settled on the island between 4000 and 1000 BC; when Christopher Columbus arrived in 1494, there were more than 200 villages ruled by caciques. The south coast of Jamaica was the most populated around the area now known as Old Harbour; the Taino still inhabited Jamaica when the English took control of the island in 1655. The Jamaican National Heritage Trust is attempting to locate and document any evidence of the Taino/yamaye. Today, few Jamaican natives remain. Most notably among some Maroon communities as well as within some communities in Cornwall County, Jamaica Christopher Columbus claimed Jamaica for Spain after landing there in 1494, his probable landing point was Dry Harbour, called Discovery Bay, St. Ann's Bay was named "Saint Gloria" by Columbus, as the first sighting of the land.
One and a half kilometres west of St. Ann's Bay is the site of the first Spanish settlement on the island, established in 1509 and abandoned around 1524 because it was deemed unhealthy; the capital was moved to Spanish Town called St. Jago de la Vega, around 1534. Spanish Town has the oldest cathedral of the British colonies in the Caribbean; the Spanish were forcibly evicted by the English at Ocho Rios in St. Ann. In the 1655 Invasion of Jamaica, the English, led by Sir William Penn and General Robert Venables, took over the last Spanish fort on the island; the name of Montego Bay, the capital of the parish of St. James, was derived from the Spanish name manteca bahía, alluding to the lard-making industry based on processing the numerous boars in the area. In 1660, the population of Jamaica was about 4,500 1,500 black. By the early 1670s, as the English developed sugar cane plantations and "imported" more slaves, black people formed a majority of the population; the colony was shaken and destroyed by the 1692 Jamaica earthquake.
The Irish in Jamaica formed a large part of the island's early population, making up two-thirds of the white population on the island in the late 17th century, twice that of the English population. They were brought in as indentured labourers and soldiers after the conquest of Jamaica by Cromwell's forces in 1655; the majority of Irish were transported by force as political prisoners of war from Ireland as a result of the ongoing Wars of the Three Kingdoms at the time. Migration of large numbers of Irish to the island continued into the 18th century. Jews were expelled from Spain in 1492 and forcibly converted to Christianity in Portugal, during a period of persecution by the Inquisition; some Spanish and Portuguese Jewish refugees went to the Netherlands and England, from there to Jamaica. Others were part of the Iberian colonisation of the New World, after overtly converting to Catholicism, as only Catholics were allowed in the Spanish colonies. By 1660, Jamaica had become a refuge for Jews in the New World attracting those, expelled from Spain and Portugal.
An early group of Jews arrived in 1510, soon after the son of Christopher Columbus settled on the island. Working as merchants and traders, the
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
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
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.
West Indies cricket team
The West Indies cricket team, traditionally known as the Windies, is a multi-national cricket team representing the Anglophone Caribbean region and administered by Cricket West Indies. The players on this composite team are selected from a chain of fifteen Caribbean territories, which are parts of several different countries and dependencies; as of 24 June 2018, the West Indian cricket team is ranked ninth in the world in Tests, ninth in ODIs and seventh in T20Is in the official ICC rankings. From the mid-late 1970s to the early 1990s, the West Indies team was the strongest in the world in both Test and One Day International cricket. A number of cricketers who were considered among the best in the world have hailed from the West Indies: Sir Garfield Sobers, Lance Gibbs, George Headley, Brian Lara, Clive Lloyd, Malcolm Marshall, Sir Andy Roberts, Rohan Kanhai, Sir Frank Worrell, Sir Clyde Walcott, Sir Everton Weekes, Sir Curtly Ambrose, Michael Holding, Courtney Walsh, Joel Garner, Sir Viv Richards and Sir Wes Hall have all been inducted into the ICC Hall of Fame.
The West Indies have won the ICC Cricket World Cup twice, the ICC World Twenty20 twice, the ICC Champions Trophy once, the ICC Under 19 Cricket World Cup once, have finished as runners-up in the Cricket World Cup, the Under 19 Cricket World Cup, the ICC Champions Trophy. The West Indies appeared in three consecutive World Cup finals, were the first team to win back-to-back World Cups; the West Indies has hosted the 2007 Cricket World Cup and the 2010 ICC World Twenty20.

The Leeward Islands Cricket Association consists of associations of one sovereign state, the two entities of Saint Kitts and Nevis, three British Overseas Territories and two other dependencies. The Windward Islands Cricket Board of Control consists of associations of four sovereign states. Cayman Islands and Turks and Caicos Islands, other historical parts of the former West Indies Federation and now British Overseas Territories, have their own teams. National teams exist for the various islands, which, as they are all separate countries much keep their local identities and support their local favourites; these national teams take part in the Carib Beer Cup. It is common for other international teams to play the island teams for warm-up games before they take on the combined West Indies team; the population of these countries and dependencies is estimated at around 6 million, more than Scotland and the Republic of Ireland. The member associations of Cricket West Indies are: Barbados Cricket Association Guyana Cricket Board Jamaica Cricket Association Trinidad & Tobago Cricket Board Leeward Islands Cricket Association.
The WICB joined the sport's international ruling body, the Imperial Cricket Conference, in 1926, played their first official international match, granted Test status, in 1928, thus becoming the fourth Test nation. In their early days in the 1930s, the side represented the British colonies that would form the West Indies Federation plus British Guiana; the last series the West Indies played before the outbreak of the Second World War was against England in 1939. There followed a hiatus. Of the West Indies players in that first match after the war only Gerry Gomez, George Headley, Jeffrey Stollmeyer, Foffie Williams had played Test cricket. In 1948, leg spinner Wilfred Ferguson became the first West Indian bowler to take ten wickets in a Test, finishing with 11/229 in a match against England.
In cricket, batting is the act or skill of hitting the ball with a bat to score runs or prevent the loss of one's wicket. Any player, batting is denoted as a batsman, batswoman, or batter, regardless of whether batting is their particular area of expertise. Batsmen have to adapt to various conditions when playing on different cricket pitches in different countries - therefore, as well as having outstanding physical batting skills, top-level batsmen will have lightning reflexes, excellent decision-making and be good strategists. During an innings two members of the batting side are on the pitch at any time: the one facing the current delivery from the bowler is denoted the striker, while the other is the non-striker; when a batsman is out, they are replaced by a teammate. This continues until the end of the innings, when 10 of the team members are out, where upon the other team gets a turn to bat. Batting tactics and strategy vary depending on the type of match being played as well as the current state of play.
The main concerns for the batsmen are not to lose their wicket and to score as many runs as as possible. These objectives conflict – to score risky shots must be played, increasing the chance that the batsman will be dismissed, while the batsman's safest choice with a careful wicket-guarding stroke may be not to attempt any runs at all. Depending on the situation, batsmen may forget attempts at run-scoring in an effort to preserve their wicket, or may attempt to score runs as as possible with scant concern for the possibility of being dismissed; as with all other cricket statistics, batting statistics and records are given much attention and provide a measure of a player's effectiveness. The main statistic for batting is a player's batting average; this is calculated by dividing the number of runs he has scored, not by the innings he has played, but by the number of times he has been dismissed. Sir Donald Bradman set many batting records, some as far back as the 1930s and still unbeaten, he is regarded as the greatest batsman of all time.
Any player, regardless of their area of special skill, is referred to as a batsman while they are batting. However, a player, in the team principally because of their batting skill is referred to as a specialist batsman, or batsman, regardless of whether they are batting. In women's cricket, the term bats woman is sometimes encountered, as is batter, but'batsman' is used in both men's and women's cricket; the batsman's act of hitting the ball is called a stroke. Over time a standard batting technique has been developed, used by most batsmen. Technique refers to the batsman's stance before the ball is bowled as well as the movement of the hands, feet and body in the execution of a cricket stroke. Good technique is characterized by getting into the correct position to play the shot getting one's head and body in line with the ball, one's feet placed next to where the ball would bounce and swinging the bat at the ball to make contact at the precise moment required for the particular stroke being played.
The movement of the batsman for a particular delivery depends on the shot being attempted. Front-foot shots are played with the weight on the front foot and are played when the ball is pitched up to the batsman, while back-foot shots are played putting the weight onto the back foot to bowling, pitched short. Shots may be described as vertical bat shots, in which the bat is swung vertically at the ball, or horizontal or cross-bat shots, in which the bat is swung horizontally at the ball. While a batsman is not limited in where or how he may hit the ball, the development of good technique has gone hand in hand with the development of a standard or orthodox cricket shots played to specific types of deliveries; these "textbook" shots are standard material found in many coaching manuals. The advent of limited overs cricket, with its emphasis on rapid run-scoring, has led to increasing use of unorthodox shots to hit the ball into gaps where there are no fielders. Unorthodox shots are typical – but not always – more high-risk than orthodox shots due to some aspects of good batting technique being abandoned.
The stance is the position. An ideal stance is "comfortable and balanced", with the feet 40 centimetres apart and astride the crease. Additionally, the front shoulder should be pointing down the wicket, the head facing the bowler, the weight balanced and the bat near the back toe; as the ball is about to be released, the batsman will lift his bat up behind in anticipation of playing a stroke and will shift his weight onto the balls of his feet. By doing this he is ready to move swiftly into position to address the ball once he sees its path out of the bowler's hand. Although this textbook, the side-on stance is the most common, a few international batsmen, such as Shivnarine Chanderpaul, use an "open" or "square on" stance; the term used to describe. While the bat should be raised as vertically as possible, coaching manuals suggest that correct technique is for the bat to be angled from the perpendicular; some players have employed an exaggerated backlift. Others, who have employed the more unorthodox open stanc
Batting average (cricket)
In cricket, a player's batting average is the total number of runs they have scored divided by the number of times they have been out. Since the number of runs a player scores and how they get out are measures of their own playing ability, independent of their teammates, batting average is a good metric for an individual player's skill as a batter; the number is simple to interpret intuitively. If all the batter's innings were completed, this is the average number of runs they score per innings. If they did not complete all their innings, this number is an estimate of the unknown average number of runs they score per innings; each player has several batting averages, with a different figure calculated for each type of match they play, a player's batting averages may be calculated for individual seasons or series, or at particular grounds, or against particular opponents, or across their whole career. Batting average has been used to gauge cricket players' relative skills since the 18th century.
Most players have career batting averages in the range of 20 to 40. This is the desirable range for wicket-keepers, though some fall short and make up for it with keeping skill; until a substantial increase in scores in the 21st century due to improved bats and smaller grounds among other factors, players who sustained an average above 50 through a career were considered exceptional, before the development of the heavy roller in the 1870s an average of 25 was considered good. All-rounders who are more prominent bowlers than batsmen average something between 20 and 30. 15 and under is typical for specialist bowlers. A small number of players have averaged less than 5 for a complete career, though a player with such an average is a liability unless an exceptional bowler as Alf Valentine, B. S. Chandrasekhar or Glenn McGrath were. Career records for batting average are subject to a minimum qualification of 20 innings played or completed, in order to exclude batsmen who have not played enough games for their skill to be reliably assessed.
Under this qualification, the highest Test batting average belongs to Australia's Sir Donald Bradman, with 99.94. Given that a career batting average over 50 is exceptional, that only five other players have averages over 60, this is an outstanding statistic; the fact that Bradman's average is so far above that of any other cricketer has led several statisticians to argue that, statistically at least, he was the greatest athlete in any sport. Disregarding this 20 innings qualification, the highest career test batting average is 112, by Andy Ganteaume, a Trinidadian Keeper-batsman, dismissed for 112 in his only test innings. Batting averages in One Day International cricket tend to be lower than in Test cricket, because of the need to score runs more and take riskier strokes and the lesser emphasis on building a large innings, it should be remembered in relation to the ODI histogram above, that there were no ODI competitions when Bradman played. If a batter has been dismissed in every single innings this statistic gives the average number of runs they score per innings.
However, for a batter with innings which finished not out, the true average number of runs they score per innings is unknown as it is not known how many runs they would have scored if they could have completed all their not out innings. This statistic is an estimate of the average number of runs. If their scores have a geometric distribution this statistic is the maximum likelihood estimate of their true unknown average. Batting averages can be affected by the number of not outs. For example, Phil Tufnell, noted for his poor batting, has an respectable ODI average of 15, despite a highest score of only 5 not out, as he scored an overall total of 15 runs from 10 innings, but was out only once. A batter who has not been dismissed in any of the innings over which their average is being calculated does not have a batting average, as dividing by zero does not give a result.

Alternative measures of batting effectiveness have been developed, including: Strike rate measures a different concept to batting average – how the batter scores – so it does not supplant the role of batting average, it is used in limited overs matches, where the speed at which a batter scores is more important than it is in first-class cricket. A system of player rankings was developed to produce a better indication of players' current standings than is provided by comparing their averages. Cricket statistics Batting average Bowling average
