The Underarm delivery 

We have to go way back to 1981 to find our most unsporting and controversial moment in cricketing history. During an ODI match between Australia and neighbouring New Zealand, the Black Caps needed only six runs to win from the final ball. Since the only way to achieve six runs in single ball was by clearing the boundary ropes, then Aussie captain Greg Chappell had told his bowler (and his brother) Trevor to deliver a grounded underarm ball. That made it literally impossible for the New Zealanders to score anything off the ball, let alone a six. The incident was considered as one of the darkest and the most unsporting moments of the great sport. Even though Australia won the game; they lost at many people’s heart because of the unsporting action they took that day.
