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.[1][2][3][4] 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.[5] John Arlott called him, “a cricketer of effect rather than the graces”.[6] An animated presence at the batting crease, he constantly adjusted his equipment and clothing, and restlessly tapped his bat on the ground as the bowler ran in. Basing his game on a sound defence learned during many hours of childhood lessons, Chappell employed the drive and square cut to full effect.[5] He had an idiosyncratic method of playing back and across to a ball of full length and driving wide of mid on,[7] but his trademark shot was the hook. A specialist slip fielder, he was the fourth player to take one hundred Test catches. Since his retirement in 1980, he has pursued a high-profile career as a sports journalist and cricket commentator, predominately with Channel Nine.[4] He remains a major figure in Australian cricket: in 2006, Shane Warne called Chappell the biggest influence on his career.[8]
