The underarm bowling incident of 1981 is a sporting controversy that took place on 1 February 1981, when Australia played New Zealand in a One Day International cricket match, the third in the best-of-five final of the 1980–81 World Series Cup, at the Melbourne Cricket Ground.[1]
With one ball of the final over remaining in the match, New Zealand required a six to tie the match. To ensure that New Zealand were unable to achieve this, the Australian captain Greg Chappell instructed his bowler (and younger brother) Trevor Chappell to deliver the last ball to batsman Brian McKechnie underarm along the ground. Trevor did so, forcing McKechnie to play the ball defensively, meaning Australia won. This action, although legal at the time, was nevertheless widely perceived as being wholly against the traditional spirit of cricketing fair play.
The outrage caused by the incident eventually led to an official amendment to the international laws of cricket to prevent it from occurring again.
