High Quality Content by WIKIPEDIA articles! Ian Michael Chappell (born 26 September 1943) is a former cricketer who played for South Australia and Australia. He captained Australia between 1971 and 1975 before taking a central role in the breakaway World Series Cricket organisation. Born into a cricketing family—his grandfather and brother also captained Australia—Chappell made a hesitant start to international cricket playing as a right-hand middle-order batsman and spin bowler. He found his niche when promoted to bat at number three. Known as “Chappelli”, he earned a reputation as one of the greatest captains the game has seen. Chappell`s blunt verbal manner led to a series of confrontations with opposition players and cricket administrators; the issue of sledging first arose during his tenure as captain and he was a driving force behind the professionalisation of Australian cricket in the 1970s.
