The underarm bowling incident of 1981 took place on February 1st 1981, when Australia played New Zealand in a One Day International cricket match, the third of five such matches in the final of the Benson & Hedges World Series Cup, at the Melbourne Cricket Ground. With one ball of the final over remaining, New Zealand required a six to tie the match. To ensure that New Zealand did not get the runs they needed, the Australian captain, Greg Chappell, instructed his bowler (and younger brother), Trevor Chappell, to deliver the last ball underarm, along the ground. This action was legal at the time, but nevertheless seen as being against the spirit of cricketing fair play.
The series was tied 1–1, with New Zealand having won the first match, and Australia the second. At the end of the third match, the batsman at the non-striker's end, Bruce Edgar, was on 102 not out, and his innings has been called "the most overlooked century of all time".
The match had already had a moment of controversy earlier. During the Australian innings, Martin Snedden claimed a low outfield catch off the batting of Greg Chappell when Chappell was on 58. In his live commentary former Australian cricket captain Richie Benaud exclaimed "that is one of the best catches I have ever seen in my life".
Snedden's catch was ruled not out by the umpires. It was some years before TV replays could be used in umpiring decisions. However the Channel Nine TV broadcast did show viewers a number of slow motion replays of Snedden's catch from a number of different TV angles including a close up of Snedden diving to fairly claim the catch. After reviewing several TV replays Benaud re-affirmed what he had initially seen live, stating in his commentary: "there is no question in my mind that that was a great catch - clearly caught above the ground, a superb catch."
