Trevor Martin Chappell is a former Australian cricketer, a member of the South Australian Chappell family which excelled at cricket. He played 3 tests and 20 One Day Internationals for Australia. He won the Sheffield Shield with New South Wales twice, and scored a century for Australia against India in the 1983 World Cup. His career was overshadowed, however, by an incident in 1981 in which he controversially bowled an underarm delivery to New Zealand cricketer Brian McKechnie to prevent the batsman from hitting a six.
