In the sport of cricket, throwing, commonly referred to as chucking, is an illegal bowling action which occurs when a bowler straightens their arm when delivering the ball. The Laws of Cricket specify that a bowler's arm must not extend during the bowling action. Only the rotation of the shoulder can be used to impart velocity to the ball. Throws are not allowed. If the umpire deems that the ball has been thrown, he will call a no ball which means the batsman cannot be given out from that delivery. Current regulations of the International Cricket Council (ICC) set the legal limit of 15 degrees of permissible straightening of the elbow joint for all bowlers in international cricket. This law applies between the point at which the bowling arm passes above shoulder height and the point at which the ball is released. The limit is to allow some natural flexing of the elbow joint which happens during the course of legal delivery. The charge of 'throwing' against a bowler is one of the most serious and controversial that can be made in cricket, as a bowler with an illegal action cannot dismiss a batsman. This means the player cannot effectively participate in the game, and may not be selected again without significant change to the way they bowl. ==Overview and history== Law 24, Clause 3 defines a fair delivery with respect to the arm: Before the advent of developed biomechanical and audiovisual technology, this law was implemented by the on-field umpires, who judged a delivery as illegal or "thrown" on visual judgement alone. The law against throwing has not changed in its essence since overarm bowling was legalised in 1864. Tom Wills, Australia's most revered cricketer of the mid-19th century, was also its most controversial, and he was often accused of (and admitted to) throwing. Many of his contemporaries recalled his trickery: "() used to say to the umpire, 'Just look at my feet, will you; I have a bad habit now and then of going over the crease.' The umpire would look at Tom's feet, and Tom would let go a throw for all he was worth."〔Felix (2 February 1901). ("The bowling trouble" ), ''The Australasian''.〕 In 1872 he became the first cricketer to be called for throwing in a major Australian match, effectively ending his first-class career. In the early 1880s there were a number of bowlers who were widely considered to have unfair actions, with the Lancashire pair of Jack Crossland and George Nash coming in for particular criticism. After playing for Kent against Lancashire in 1885, when he faced the bowling of Crossland and Nash, Lord Harris decided to take action. He persuaded the Kent committee to cancel the return fixture. Later that season, Crossland was found to have broken his residential qualification for Lancashire by living in Nottinghamshire, and Nash dropped out of the side. Thus the two counties resumed playing each other the following season. Harris's ''Wisden'' obituarist wrote: "...there can be no doubt the action of Lord Harris, even if it did not entirely remove the throwing evil, had a very healthy effect on the game." Sydney Pardon, the editor of ''Wisden'', accused quick bowler Ernest Jones of throwing during Australia's tour of England in 1896 but it was left to an Australian umpire, Jim Phillips, to "call" Jones for throwing in the Melbourne Test in 1897. The same umpire ended the great C.B. Fry's bowling career by calling him for throwing. Pardon considered the end of the famous Corinthian's bowling career "a case of long-delayed justice". Phillips went on to call Lancashire and England fast bowler Arthur Mold in 1900 and 1901, so effectively ending his productive career. Mold took 1,673 wickets in first-class cricket at only 15.54 apiece, bowling at high pace with a sharp 'break back' from just a four pace run up, but his bowling had always attracted as much controversy as praise. He took 192 wickets in 1895 and was a Wisden Cricketer of the Year in 1892 but he left the first class scene after the 1901 season after Phillips' intervention. The Australian aboriginal fast bowler Eddie Gilbert was another fast bowler who generated extreme pace from a remarkably short run. Just 5 feet 7 inches tall and nine stone in weight he took wickets at a prodigious rate in the late 1920s in Queensland club cricket. He was chosen for Queensland against New South Wales Colts in 1930 and took 6 wickets, but the Brisbane Courier's correspondent "Long On" was moved to describe his whipped catapult action as "almost a throw". He was picked for Queensland's Sheffield Shield side and bowled with great success. Queensland selectors responded to complaints from New South Wales by filming his arm action in slow motion but took no action against him. His most famous spell came against Don Bradman on 6 November 1931. He dismissed the NSW opener with his first ball, a vicious bouncer, then knocked Bradman's bat out of his hands with the next. The next delivery knocked Bradman over and the third had him caught behind. A month later, playing against Victoria, he was repeatedly called for throwing. He played on for Queensland, bowling at a reduced pace, and in 1934-35 headed the Queensland averages. He was a victim of legislation outlawing intimidatory bowling, in the wake of the Bodyline affair, and retired in 1936, having taken 87 first class wickets at 29.21. He later suffered from mental illness. An epidemic of throwing plagued cricket in the 1950s. Umpire Frank Chester wanted to no-ball the South African Cuan McCarthy for throwing in 1951, but was blocked by the authorities at Lords, Plum Warner commenting diplomatically "These people are our guests". Surrey and England left-arm spinner Tony Lock was generally thought to throw his dangerous faster ball, on one occasion Doug Insole inquiring if he had been 'bowled or run out' after Lock had shattered his stumps. Left-arm paceman Ian Meckiff helped Australia to regain the Ashes in 1958-59 but feelings ran high in the England team and press that Meckiff, and others, bowled outside the laws and spirit of the game. Elder statesmen on both sides, including Gubby Allen and Don Bradman, resolved to clear the air before Australia's tour of England in 1961. In 1963–64, Meckiff was called by Colin Egar in the First Test against South Africa in Brisbane, ending his career. Twenty-one-year-old South African Geoff Griffin, who had already been called when playing for Natal, was called in May 1960 while playing against MCC at Lords and his test career was ended by umpire Frank Lee who called him four times during the Second Test. Remarkably he claimed a hat trick during the test, but South Africa lost by an innings, prompting an exhibition match to be staged as the Queen was due to visit the ground. Griffin was called by umpire Syd Buller, ending an over bowling underarm when he was no balled again for not informing the umpire of a change of action. West Indian fast bowler Charlie Griffith, perhaps the most feared fast bowler of his generation, was often suspected of throwing his faster ball although he was not called in Test matches and the promising career of Derbyshire's Harold Rhodes was stunted by constant speculation about the legality of his action. He was 'called' while playing against the South African tourists in 1960 by Paul Gibb but through he was eventually cleared and played on with great success for Derbyshire though the decade, he played just twice for England. In more recent times bowlers such as England's James Kirtley, Australia's Brett Lee and Pakistan's Shoaib Akhtar and Shabbir Ahmed have fallen under the microscope to varying degrees. Muttiah Muralitharan, one of the modern era's most celebrated exponents of spin bowling was dogged by controversy over his bowling action for much of his international career. Since his debut, he was under scrutiny from umpires due to an unusual hyperextension of his congenitally bent arm during delivery. Despite initial criticism, the first occasion when his action became a real issue was when Australian umpire Darrell Hair called him for throwing during the Boxing Day Test in Melbourne, 1995. Biomechanical trials exonerated him in the eyes of the ICC, but some players, umpires and spectators remain unconvinced. Hair publicly stated that he wouldn't hesitate to call Murali for throwing again, given the opportunity, and considered his bowling action "diabolical". The inability of cricket's officials to agree on the legality of Muralitharan's action, and the reluctance of other umpires to call him for throwing meant Hair was isolated and was later excluded from officiating in matches involving Sri Lanka. Subsequent bio-mechanical tests exonerated Muralitharan's action, showing that he did not extend his arm any more than many other bowlers with legal actions. Unfortunately this testing never completely cleared his action in the eyes of his critics, who claim the extension of the arm differs between bowling in testing and in game situations, and also when he bowls particular deliveries. During testing at the University of Western Australia several independent witnesses, including former cricketer Bruce Yardley were present to ensure Muralitharan bowled as he would in match conditions.〔(【引用サイトリンク】title=Q+A: Cricket - Muttiah Muralitharan's bowling action )〕〔(【引用サイトリンク】title=Bowling Report: Testing Muralitharan's Doosra )〕 Since the mid-1990s when Pakistani off-spinner Saqlain Mushtaq pioneered the doosra, off spinners who have bowled with a non-classical action that can produce this delivery have routinely been reported and investigated for throwing, although none have been sanctioned. Such bowlers include Harbhajan Singh, Shoaib Malik, Marlon Samuels, Mohammad Hafeez, Saeed Ajmal, Johan Botha and Shane Shillingford. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Throwing (cricket)」の詳細全文を読む スポンサード リンク
