Bodyline, also known as fast leg theory bowling, was a cricketing tactic devised by the English cricket team for their 1932–33 Ashes tour of Australia. It was designed to combat the extraordinary batting skill of Australia's leading batsman, Don Bradman. A bodyline delivery was one in which the cricket ball was bowled at pace, aimed at the body of the batsman in the expectation that when he defended himself with his bat, a resulting deflection could be caught by one of several fielders deliberately placed nearby on the leg side.
At the time, no helmets or other upper-body protective gear was worn, and critics of the tactic considered it intimidating, and physically threatening in a game traditionally supposed to uphold conventions of sportsmanship. The England team's use of the tactic was perceived by some, both in Australia and England, as overly aggressive or even unfair. It caused a controversy that rose to such a level that it threatened diplomatic relations between the two countries before the situation was calmed. (Full article...)
