The wicket-keeper in the sport of cricket is the player on the fielding side who stands behind the wicket or stumps being watchful of the batsman and be ready to take a catch, stump the batsman out and run out a batsman when occasion arises. The wicket-keeper is the only member of the fielding side permitted to wear gloves and external leg guards; the role of the keeper is governed by Law 27 of the Laws of Cricket. During the bowling of the ball the wicket-keeper crouches in a full squatting position but stands up as the ball is received. Australian wicket-keeper Sammy Carter was the first to squat on his haunches rather than bend over from the waist; the keeper's major function is to stop deliveries that pass the batsman, but he can attempt to dismiss the batsman in various ways: The most common dismissal effected by the keeper is for him to catch a ball that has nicked the batsman's bat, called an edge, before it bounces. Sometimes the keeper is in the best position to catch a ball, hit high in the air.
More catches are taken by wicket-keepers than by any other fielding position. The keeper can stump the batsman by using the ball to remove the bails from the stumps, if the batsman is out of his crease after a delivery has passed the stumps into the keeper's hands; the keeper must dislodge the bail and the batsman is out if he is still outside the crease. When the ball is hit into the outfield, the keeper moves close to the stumps to catch the return throw from a fielder and, if possible, to run out a batsman. A keeper's position depends on the bowler: for fast bowling he will squat some distance from the stumps, in order to have time to react to edges from the batsman, while for slower bowling, he will come much nearer to the stumps, to pressure the batsman into remaining within the crease or risk being stumped; the more skilled the keeper, the faster the bowling to which he is able to "stand up", for instance Godfrey Evans stood up to Alec Bedser. Like the other players on a cricket team, keepers will bat during the team’s batting innings.
At elite levels, wicket-keepers are expected to be proficient batters, averaging more than specialist bowlers. See Wicket-keeper-batsman. Law 27.2, which deals with the specifications for wicketkeepers' gloves, states that: If... the wicket-keeper wears gloves, they shall have no webbing between the fingers except joining index finger and thumb, where webbing may be inserted as a means of support. If used, the webbing shall be a single piece of non-stretch material which, although it may have facing material attached, shall have no reinforcements or tucks; the top edge of the webbing shall not protrude beyond the straight line joining the top of the index finger to the top of the thumb and shall be taut when a hand wearing the glove has the thumb extended. Substitutes were not allowed to keep wicket, but this restriction was lifted in the 2017 edition of the Laws of Cricket; this rule was sometimes suspended, by agreement with the captain of the batting side. For example, during the England–New Zealand Test Match at Lord's in 1986, England's specialist keeper, Bruce French was injured during England's first innings.
England used 4 keepers in New Zealand's first innings: Bill Athey kept for the first two overs. Arthur Jones was the first substitute to keep wicket in a Test match, when he did so against Australia at The Oval in 1905. There is no rule stating. On 5 June 2015 during a T20 Blast game between the Worcestershire Rapids and the Northamptonshire Steelbacks, Worcestershire chose not to play a wicket-keeper in the 16th over of the match, their keeper, Ben Cox, became an extra fielder at fly slip. The umpires consulted with each other and agreed that there was nothing in the rules to prevent it from happening; the following are the top 10 wicket-keepers by total dismissals in Test cricket. The following are the top 10 wicket-keepers by total dismissals in one day cricket; the following are the top 10 wicket-keepers by total dismissals in Twenty20 International cricket.

Australia national cricket team
The Australia national cricket team is the joint oldest team in Test cricket history, having played in the first Test match in 1877. The team plays One-Day International and Twenty20 International cricket, participating in both the first ODI, against England in the 1970–71 season and the first T20I, against New Zealand in the 2004–05 season, winning both games; the team draws its players from teams playing in the Australian domestic competitions – the Sheffield Shield, the Australian domestic limited-overs cricket tournament and the Big Bash League. The national team has played 820 Test matches, winning 386, losing 222, drawing 210 and tying 2; as of March 2019, Australia is ranked fourth in the ICC Test Championship on 104 rating points. Australia is the most successful team in Test cricket history, in terms of overall wins, win-loss ratio and wins percentage; the Australian cricket team has played 932 ODI matches, winning 566, losing 323, tying 9 and with 34 ending in a no-result. As of March 2019, Australia is ranked fifth in the ICC ODI Championship on 102 rating points, though have been ranked first for 141 of 185 months since its introduction in 2002.
Australia have made a record seven World Cup final appearances and have won the World Cup a record five times in total. Australia is the first team to appear in four consecutive World Cup finals, surpassing the old record of three consecutive World Cup appearances by the West Indies and the first team to win 3 consecutive World Cups; the team was undefeated in 34 consecutive World Cup matches until 19 March at the 2011 Cricket World Cup where Pakistan beat them by 4 wickets. It is the second team to win a World Cup on home soil, after India. Australia have won the ICC Champions Trophy twice making them the first and the only team to become back to back winners in the Champions Trophy tournaments; the national team has played 116 Twenty20 International matches, winning 60, losing 52, tying 2 and with 2 ending in a no-result. As of March 2019, Australia is ranked third in the ICC T20I Championship on 120 rating points. Additionally, the team made the final of the 2010 ICC World Twenty20. On 12 January 2019, Australia won the first ODI against India at the Sydney Cricket Ground by 34 runs, to record their 1,000th win in international cricket.
The Australian cricket team participated in the first Test match at the MCG in 1877, defeating an English team by 45 runs, with Charles Bannerman making the first Test century, a score of 165 retired hurt. Test cricket, which only occurred between Australia and England at the time, was limited by the long distance between the two countries, which would take several months by sea. Despite Australia's much smaller population, the team was competitive in early games, producing stars such as Jack Blackham, Billy Murdoch, Fred "The Demon" Spofforth, George Bonnor, Percy McDonnell, George Giffen and Charles "The Terror" Turner. Most cricketers at the time were either from New South Wales or Victoria, with the notable exception of George Giffen, the star South Australian all-rounder. A highlight of Australia's early history was the 1882 Test match against England at The Oval. In this match, Fred Spofforth took 7/44 in the game's fourth innings to save the match by preventing England from making their 85-run target.
After this match The Sporting Times, a major newspaper in London at the time, printed a mock obituary in which the death of English cricket was proclaimed and the announcement made that "the body was cremated and the ashes taken to Australia." This was the start of the famous Ashes series in which Australia and England play a series of Test matches to decide the holder of the Ashes. To this day, the contest is one of the fiercest rivalries in sport; the so-called'Golden Age' of Australian Test cricket occurred around the end of the 19th century and the beginning of the 20th century, with the team under the captaincy of Joe Darling, Monty Noble and Clem Hill winning eight of ten tours. It is considered to have lasted from the 1897–98 English tour of Australia and the 1910–11 South African tour of Australia. Outstanding batsmen such as Joe Darling, Clem Hill, Reggie Duff, Syd Gregory, Warren Bardsley and Victor Trumper, brilliant all-rounders including Monty Noble, George Giffen, Harry Trott and Warwick Armstrong and excellent bowlers including Ernie Jones, Hugh Trumble, Tibby Cotter, Bill Howell, Jack Saunders and Bill Whitty, all helped Australia to become the dominant cricketing nation for most of this period.
Victor Trumper became one of Australia's first sporting heroes, was considered Australia's greatest batsman before Bradman and one of the most popular players. He played a record number of Tests at 49 and scored 3163 runs at a high for the time average of 39.04. His early death in 1915 at the age of 37 from kidney disease caused national mourning; the Wisden Cricketers' Almanack, in its obituary for him, called him Australia's greatest batsman: "Of all the great Australian batsmen Victor Trumper was by general consent the best and most brilliant."The years leading up to the start of World War I were marred by conflict between the players, led by Clem Hill, Victor Trumper and Frank Laver, the Australian Board of Control for International Cricket, led by Peter McAlister, attempting to gain more control of tours from the players. This led to six leading players walking out on the 1912 Triangular Tournament in England, with Australia fielding what was considered a second-rate side; this was the last series before the war, no more cricket was played by A
Test cricket is the form of the sport of cricket with the longest duration, is considered the game's highest standard. Test matches are played between national representative teams with "Test status", as determined and conferred by the International Cricket Council; the term Test stems from the fact of the form's long, gruelling matches being both mentally and physically testing. Two teams of 11 players each play a four-innings match, it is considered the most complete examination of a team's endurance and ability. The first recognised Test match took place between 15 and 19 March 1877 and was played between England and Australia at the Melbourne Cricket Ground, where Australia won by 45 runs. A Test match to celebrate 100 years of Test cricket was held in Melbourne between 12 and 17 March 1977, in which Australia beat England by 45 runs—the same margin as that first Test. In October 2012, the ICC recast the playing conditions for Test matches, permitting day/night Test matches; the first day/night game took place between Australia and New Zealand at the Adelaide Oval, Adelaide, on 27 November – 1 December 2015.
Women's Test cricket is played over four days, with slight differences in format from men's Tests. Test matches are the highest level of cricket, statistically, their data form part of first-class cricket. Matches are played between national representative teams with "Test status", as determined by the International Cricket Council; as of June 2017, twelve national teams have Test status, the most promoted being Afghanistan and Ireland on 22 June 2017. Zimbabwe's Test status was voluntarily suspended, because of poor performances between 2006 and 2011. In January 2014, during an ICC meeting in Dubai, the pathway for new potential Test nations was laid out with the winners of the next round of the ICC Intercontinental Cup playing a 5-day match against the bottom ranked Test nation. If the Associate team defeats the Test nation they could be added as the new Test country and granted full membership. A list of matches, defined as "Tests", was first drawn up by Australian Clarence Moody in the mid-1890s.
Representative matches played by simultaneous England touring sides of 1891–92 and 1929–30 are deemed to have "Test status". In 1970, a series of five "Test matches" was played in England between England and a Rest of the World XI; these matches scheduled between England and South Africa, were amended after South Africa was suspended from international cricket because of their government's policy of apartheid. Although given Test status, this was withdrawn and a principle was established that official Test matches can only be between nations. Despite this, in 2005, the ICC ruled that the six-day Super Series match that took place in October 2005, between Australia and a World XI, was an official Test match; some cricket writers and statisticians, including Bill Frindall, ignored the ICC's ruling and excluded the 2005 match from their records. The series of "Test matches" played in Australia between Australia and a World XI in 1971–72 do not have Test status; the commercial "Supertests" organised by Kerry Packer as part of his World Series Cricket enterprise and played between "WSC Australia", "WSC World XI" and "WSC West Indies" from 1977 to 1979 have never been regarded as official Test matches.
There are twelve Test-playing men's teams. The teams all represent individual, independent nations, except for England, the West Indies and Ireland. Test status is conferred upon a group of countries by the International Cricket Council. Teams that do not have Test status can play in the ICC Intercontinental Cup designed to allow non-Test teams to play under conditions similar to Tests; the teams are listed below with the date of each team's Test debut: England Australia South Africa West Indies New Zealand India Pakistan Sri Lanka Zimbabwe Bangladesh Ireland Afghanistan In the mid 2010s, the ICC evaluated proposals for dividing Test cricket into two tiers, with promotion and relegation between Tier-1 and Tier-2. These proposals were opposed by others; these proposals were not implemented. A standard day of Test cricket consists of three sessions of two hours each, the breaks between sessions being 40 minutes for lunch and 20 minutes for tea; however the times of sessions and intervals may be altered in certain circumstances: if bad weather or a change of innings occurs close to a scheduled break, the break may be taken immediately.
Today, Test matches are scheduled to be played across five consecutive days
India national cricket team
The India national cricket team known as Team India and Men in Blue, is governed by the Board of Control for Cricket in India, is a full member of the International Cricket Council with Test, One Day International and Twenty20 International status. Although cricket was introduced to India by European merchant sailors in the 18th century, the first cricket club was established in Calcutta in 1792, India's national cricket team did not play its first Test match until 25 June 1932 at Lord's, becoming the sixth team to be granted Test cricket status. In its first fifty years of international cricket, India was one of the weaker teams, winning only 35 of the first 196 Test matches it played. From 1932 India had to wait until 1952 20 years for its first Test victory; the team, gained strength in the 1970s with the emergence of players such as batsmen Sunil Gavaskar and Gundappa Viswanath, all-rounder Kapil Dev and the Indian spin quartet of Erapalli Prasanna, Srinivas Venkataraghavan, Bhagwat Chandrasekhar and Bishen Singh Bedi.
Traditionally much stronger at home than abroad, the Indian team has improved its overseas form in limited-overs cricket, since the start of the 21st century, winning Test matches in Australia and South Africa. It has won the Cricket World Cup twice – in 1983 under the captaincy of Kapil Dev and in 2011 under the captaincy of Mahendra Singh Dhoni. After winning the 2011 World Cup, India became only the third team after West Indies and Australia to have won the World Cup more than once, the first cricket team to win the World Cup at home, it won the 2007 ICC World Twenty20 and 2013 ICC Champions Trophy, under the captaincy of MS Dhoni. It was the joint champions of 2002 ICC Champions Trophy, along with Sri Lanka; as of 19 October 2018, India is ranked first in Tests, second in ODIs and second in T20Is by the ICC. Virat Kohli is the current captain of the team across all formats, while the head coach is Ravi Shastri; the Indian cricket team has rivalries with other Test-playing nations, most notably with Pakistan, the political arch-rival of India.
However, in recent times, rivalries with nations like Australia, South Africa and England have gained prominence. The British brought cricket to India in the early 1700s, with the first cricket match played in 1721. In 1848, the Parsi community in Bombay formed the Oriental Cricket Club, the first cricket club to be established by Indians. After slow beginnings, the Europeans invited the Parsis to play a match in 1877. By 1912, the Parsis, Sikhs and Muslims of Bombay played a quadrangular tournament with the Europeans every year. In the early 1900s, some Indians went on to play for the England cricket team; some of these, such as Ranjitsinhji and KS Duleepsinhji were appreciated by the British and their names went on to be used for the Ranji Trophy and Duleep Trophy – two major first-class tournaments in India. In 1911, an Indian team went on their first official tour of the British Isles, but only played English county teams and not the England cricket team. India was invited to The Imperial Cricket Council in 1926, made their debut as a Test playing nation in England in 1932, led by CK Nayudu, considered as the best Indian batsman at the time.
The one-off Test match between the two sides was played at Lord's in London. The team went on to lose by 158 runs. India hosted its first Test series in the year 1933. England was the visiting team that played 2 Tests in Calcutta; the visitors won the series 2-0. The Indian team continued to improve throughout the 1930s and'40s but did not achieve an international victory during this period. In the early 1940s, India didn't play any Test cricket due to the Second World War; the team's first series as an independent country was in late 1947 against Sir Donald Bradman's Invincibles. It was the first Test series India played, not against England. Australia won the five-match series 4–0, with Bradman tormenting the Indian bowling in his final Australian summer. India subsequently played their first Test series at home not against England against the West Indies in 1948. West Indies won the 5-Test series 1–0. India recorded their first Test victory, in their 24th match, against England at Madras in 1952.
In the same year, they won their first Test series, against Pakistan. They continued their improvement throughout the early 1950s with a series win against New Zealand in 1956. However, they did not win again in the remainder of the decade and lost badly to strong Australian and English sides. On 24 August 1959, India lost by an innings in the Test to complete the only 5–0 whitewash inflicted by England; the next decade saw. They won their first Test series against England at home in 1961–62 and won a home series against New Zealand, they managed to draw another series against England. In this same period, India won its first series outside the subcontinent, against New Zealand in 1967–68; the key to India's bowling in the 1970s were the Indian spin quartet – Bishen Bedi, E. A. S. Prasanna, BS Chandrasekhar and Srinivas Venkataraghavan; this period saw the emergence of two of India's best batsmen, Sunil Gavaskar and Gundappa Viswanath. Indian pitches have had the tendency to support spin and the spin quartet exploited this to create collapses in opposing batting line-ups.
These players were responsible for the back-to-back series wins in 1971 in the West Indies and in England, under the captaincy of Ajit Wadekar
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
Kochi known as Cochin, is a major port city on the south-west coast of India bordering the Laccadive Sea. It is part of the district of Ernakulam in the state of Kerala and is referred to as Ernakulam. Kochi is the most densely populated city in Kerala; as of 2011, it has a corporation limit population of 677,381 within an area of 94.88 km² and a total urban population of more than of 2.1 million within an area of 440 km², making it the largest and the most populous metropolitan area in Kerala. Kochi city is part of the Greater Cochin region and is classified as a Tier-II city by the Government of India; the civic body that governs the city is the Kochi Municipal Corporation, constituted in the year 1967, the statutory bodies that oversee its development are the Greater Cochin Development Authority and the Goshree Islands Development Authority. Called the Queen of the Arabian Sea, Kochi was an important spice trading centre on the west coast of India from the 14th century onward, maintained a trade network with Arab merchants from the pre-Islamic era.
Occupied by the Portuguese in 1503, Kochi was the first of the European colonies in colonial India. It remained the main seat of Portuguese India until 1530; the city was occupied by the Dutch and the British, with the Kingdom of Cochin becoming a princely state. Kochi ranks first in the total number of domestic tourist arrivals in Kerala; the city was ranked the sixth best tourist destination in India according to a survey conducted by the Nielsen Company on behalf of the Outlook Traveller magazine. Kochi was one of the 28 Indian cities among the emerging 440 global cities that will contribute 50% of the world GDP by the year 2025, in a 2011 study done by the McKinsey Global Institute. In July 2018, Kochi was ranked the topmost emerging future megacity in India by global professional services firm JLL. Kochi is known as the financial and industrial capital of Kerala, it has the highest GDP as well as the highest GDP per capita in the state. The city is home to the Southern Naval Command of the Indian Navy and is the state headquarters of the Indian Coast Guard with an attached air squadron, named Air Squadron 747.
Commercial maritime facilities of the city include the Port of Kochi, an International Container Transshipment Terminal, the Cochin Shipyard, offshore SPM of the BPCL Kochi Refinery and the Kochi Marina. Kochi is home for the Cochin Stock Exchange, International Pepper Exchange, Marine Products Export Development Authority, Coconut Development Board, companies like HMT, Apollo Tyres and Synthite, petrochemical companies like the FACT, TCC, IREL, Petronet LNG, Merchem, HOCL and Kochi Refineries, electrical companies like TELK, V-Guard and industrial parks like the Cochin Special Economic Zone, Smart City and Kinfra Hi-Tech Park. Kochi is home for the High Court of Kerala and Lakshadweep, Naval Physical and Oceanographic Laboratory, Indian Maritime University, Sree Sankaracharya Sanskrit University and the Cochin University of Science and Technology. Kochi is home to Kerala's National Law School, the National University of Advanced Legal Studies. Kochi has been hosting India's first art biennale, the Kochi-Muziris Biennale, since 2012, which attracts international artists and tourists.
Ancient travellers and tradesmen referred to Kochi, variously alluding to it as Cocym, Cochym and Kochi. The Cochin Jewish community called Cochin "Kogin", seen in the seal of the synagogue owned by the community; the origin of the name "Kochi" is thought to be from the Malayalam word kochu azhi, meaning'small lagoon'. Yet another theory is that Kochi is derived from the word Kaci, meaning "harbour". Accounts by Italian explorers Nicolo Conti, Fra Paoline in the 17th century say that it was called Kochchi, named after the river connecting the backwaters to the sea. After the arrival of the Portuguese, the British, the name Cochin stuck as the official appellation; the city reverted to a closer transliteration of its original Malayalam name, Kochi, in 1996. This change in name was challenged by the city municipal corporation but court dismissed the plea. Kochi was the centre of Indian spice trade for many centuries, was known to the Yavanas as well as Jews, Syrians and Chinese since ancient times.
It rose to significance as a trading centre after the port Muziris around Kodungallur was destroyed by massive flooding of Periyar in 1341. The earliest documented references to Kochi occur in books written by Chinese voyager Ma Huan during his visit to Kochi in the 15th century as part of Admiral Zheng He's treasure fleet. There are references to Kochi in accounts written by Italian traveller Niccolò Da Conti, who visited Kochi in 1440. On the Malabar coast during the early 15th century and Kochi were in an intense rivalry, so the Ming dynasty of China decided to intervene by granting special status to Kochi and its ruler known as Keyili to the Chinese. Calicut had been the dominant port-city in the region. For the fifth Ming treasure voyage, Admiral Zheng He was instructed to confer a seal upon Keyili of Kochi and enfeoff a mountain in his kingdom as the Zhenguo Zhi Shan. Zheng He delivered a stone tablet, inscribed with a proclamation composed by the Yongle Emperor himself, to Kochi; as long as Kochi remained under the protection of Ming China, the Zamorin of Calicut was unable to invade Kochi and a military conflict was averted.
The cessation of the Ming treasure voyages had negative results for Kochi, as the Zamorin of Calicut would launch
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.
