to attempt a run. Sometimes a batsman, whilst backing up, leaves the popping crease before the bowler has actually delivered (released) the ball. Where this has happened, the bowler may legally attempt to run the non-striking batsman out in accordance with the Laws of Cricket. If he fails, and the batsman has remained within the crease, the delivery is called a dead ball. Some observers feel that dismissing a batsman in this way is poor sporting etiquette and against the spirit of the game, but many others believe that the Laws and regulations exist to be used as a structure of the game and that, as the run out backing up is expressly within the professional regulations, it is legitimate and sporting to exercise the provision, with some drawing analogies to baseball's pickoff. According to the former convention, a generous bowler may warn a batsman to stay in his crease rather than to take his wicket, but this is not required by the Laws of Cricket nor the MCC guidance notes on the Spirit of Cricket. When the run out has happened in first-class cricket, it has on occasion provoked debate. Such dismissals have always occurred and continue to divide opinion. One of the earliest recorded examples of running out a batsman "backing up" came in a match between Eton and Harrow in 1850, when Harrow's Charles Austen-Leigh was run out "backing up" by Eton bowler William Prest. Vinoo Mankad The most famous example of this method of dismissal involved the Indian bowler Vinoo Mankad. It occurred during India's tour of Australia on 13 December 1947 in the second Test at Sydney. Mankad ran out Bill Brown when, in the act of delivering the ball, he held on to it and removed the bails with Brown well out of his crease. This was the second time Mankad had dismissed Brown in this fashion on the tour, having already done it in an earlier match against an Australian XI. On that occasion he had warned Brown once before running him out. The Australian press accused Mankad of being unsportsmanlike, although some Australians, including Don Bradman, the Australian captain at the time, defended Mankad's actions. Since this incident, a batsman dismissed in this fashion is (informally) said to have been "Mankaded".
