Top 5 most controversial moments in cricket

1. The Underarm (1981)

With New Zealand requiring six runs to tie the match, Australian captain at that time, Greg Chappell instructed his younger brother, Trevor Chappell to deliver the last ball to batsman Brian McKechnie as an underarm along the ground. Trevor did so and McKechnie had no choice but to defend as Australia went on to win the match. However, this action caused immeasurable outrage which eventually led to an official amendment to the international laws of cricket to prevent it from occurring again.
