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
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
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
Tobago is an autonomous island within the Republic of Trinidad and Tobago. It is located 35 kilometres northeast of the mainland of Trinidad and southeast of Grenada, about 160 kilometres off the coast of northeast Venezuela. According to the earliest English-language source cited in the Oxford English Dictionary, Tobago bore a name that has become the English word tobacco; the official bird of Tobago is the cocrico. Christopher Columbus first sighted Tobago on the 14th of August, 1498. Subsequently, several powers fought over possession of the island; the original Island Carib population had to defend the island against other Amerindian tribes. During the late 1500s and early 1600s, the natives defended it from European colonists, including 1654, including an attempt by the Courlanders, who colonised the island intermittently between 1637-1690. Over the ensuing years, the Curonians, English, French and Swedish had caused Tobago to become a focal point in repeated attempts of colonisation, which led to the island having changed hands 33 times, the most in Caribbean history, before the Treaty of Paris ceded it to the British in 1814.
In 1662, the Dutch brothers Adrian and Cornelius Lampsins were granted the title of Barons of Tobago, ruled until the English captured the island in 1666. Adrian recaptured Tobago in 1673, but was killed in battle when the English, under Sir Tobias Bridge yet again took control of the island. From about 1672, during the temporary British rule of 1672-1674, Tobago had a period of stability during which plantation culture began. Sugar and indigo factories sprang up and Africans were imported by the British to work as slaves; the economy flourished. France had abandoned the island to Britain in 1763, by 1777 Tobago was exporting great quantities of cotton, indigo and sugar, but in 1781, the French re-invaded Tobago, destroyed the plantations, forced the British governor to surrender. The island's buoyant economy fell into decline. In 1814, when the island again came under British control, another phase of successful sugar-production began, but a severe hurricane in 1847, combined with the collapse of plantation underwriters, end of slavery in 1834 and the competition from sugar with other European countries, marked the end of the sugar trade.
In 1889 the island became a ward of Trinidad. Without sugar, the islanders had to grow other crops, planting acres of limes and cocoa and exporting their produce to Trinidad. In 1963 Hurricane Flora ravaged Tobago, destroying the crops. A restructuring programme followed and attempts were made to diversify the economy; the development of a tourist industry began. Trinidad and Tobago obtained its independence from the British Empire in 1962 and became a republic in 1976, just as Trinidad; the population was 60,874 at the 2011 census. The capital, has a population of 17,537. While Trinidad is multiethnic, Tobago's population is of African descent, although with a growing proportion of Trinidadians of East Indian descent and Europeans. Between 2000 and 2011, the population of Tobago grew by 12.55 percent, making it one of the fastest-growing areas of Trinidad and Tobago. Local Government and Central Government functions in Tobago are handled by the Tobago House of Assembly; the current Chief Secretary of the THA is Kelvin Charles.
The People's National Movement controls 10 of the 12 seats in the Assembly, with the Progressive Democratic Patriots led by union leader Watson Duke controlling two seats since the 23 January 2017 election. Tobago has two parliamentary seats, Tobago East and Tobago West, which are controlled by the People's National Movement, which won them in the general elections of Trinidad and Tobago on 7 September 2015; the island was most featured in the international press in early 2007, for its establishment of a Minister of Mental Health. Minister Ellen Tang was appointed on the first anniversary of the launch of the Happiness Project, her aide, Melody Williams, has been allocated a major proportion of the annual housing funding to revamp government housing projects all over the island. Tobago is divided into seven parishes – three in the Western Region and four in the Eastern Region: Tobago has a land area of 300 km² and is 40 kilometres long and 10 kilometres wide, it is located at latitude 11° 15' N, longitude 60° 40' W north of Trinidad.
Tobago is hilly, mountainous and of volcanic origin. The southwest of the island is flat and consists of coralline limestone; the hilly spine of the island is called the Main Ridge. The highest point in Tobago is the 550-metre Pigeon Peak near Speyside; the climate is tropical, the island lies just south of the Atlantic hurricane belt, making it vulnerable to occasional southward-travelling tropical storms. Average rainfall varies between 3,800 mm on the Main Ridge to less than 1,250 mm in the southwest. There are two seasons: a wet season between June and December, a dry season between January and May. Due to its close proximity to the hurricane belt, the island was struck by Hurricane Flora on September 30, 1963; the effects were so severe. The hurricane laid waste to the banana and cacao plantations that sustained the economy, wreaked considerable damage on the pristine tropical rainforest that makes up a large proportion of the interior of the island's northern half. Many of the plantations were subsequently abandoned, the economy changed direction away from cash crop agriculture and toward tourism.
In 2004 Hurricane Ivan, while less severe than Flora caused significant damage. The Tobago Forest Reserve is
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
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
Stumped is a method of dismissal in cricket. The action of stumping can only be performed by a wicket-keeper and, according to the Laws of Cricket, a batsman can be given out stumped if: the wicket-keeper puts down the wicket, while the batsman is: out of his ground. Being "out of his ground" is defined as not having any part of the batsman's body or his bat touching the ground behind the crease – i.e. if his bat is elevated from the floor despite being behind the crease, or if his foot is on the crease line itself but not across it and touching the ground behind it he would be considered out. One of the fielding team must appeal for the wicket by asking the umpire; the appeal is directed to the square-leg umpire, who would be in the best position to adjudicate on the appeal. Stumping is the fifth most common form of dismissal after caught, leg before wicket and run out, though it is seen more in Twenty20 cricket because of its more aggressive batting, it is governed by Law 39 of the Laws of Cricket.
It is seen with a medium or slow bowler, as with fast bowlers a wicket-keeper takes the ball too far back from the wicket to attempt a stumping. It includes co-operation between a bowler and wicket-keeper: the bowler draws the batsman out of his ground, the wicket-keeper catches and breaks the wicket before the batsman realises he has missed the ball and makes his ground, i.e. places the bat or part of his body on the ground back behind the popping crease. If the bails are removed before the wicket-keeper has the ball, the batsman can still be stumped if the wicket-keeper removes one of the stumps from the ground, while holding the ball in his hand; the bowler is credited for the batsman's wicket, the wicket-keeper is credited for the dismissal. A batsman may be out stumped off a wide delivery but cannot be stumped off a no-ball as bowler is credited for the wicket. Notes: The popping crease is defined as the back edge of the crease marking (i.e. the edge closer to the wicket. Therefore, a batsman whose bat or foot is on the crease marking, but does not touch the ground behind the crease marking, can be stumped.
This is quite common. The wicket must be properly put down in accordance with Law 28 of the Laws of cricket: using either the ball itself or a hand or arm, in possession of the ball. Note that since the ball itself can put down the wicket, a stumping is still valid if the ball rebounds from the'keeper and breaks the wicket though never controlled by him; the wicket-keeper must allow the ball to pass the stumps before taking it, unless it has touched either the batsman or his bat first. If the wicket-keeper fails to do this, the delivery is a "no-ball", the batsman cannot be stumped
