Extensive research conducted by the International Cricket Council is set to reveal that 99% of bowlers in the history of cricket have been throwers. The study was undertaken in the wake of the furore surrounding Muttiah Muralitharan, whose doosra was banned earlier this year after Chris Broad, the match referee for the Tests against Australia, reported it to the ICC.
According to Derek Pringle in the Daily Telegraph, Murali is no different from the vast majority of his fellow players. The current law states that there should be no straightening or partial straightening of the bowling arm during delivery, and in-depth research has revealed that even bowlers like Glenn McGrath and Shaun Pollock, usually considered examplars of the classical action, occasionally go over the prescribed tolerance limit, bending their arms by as much as 12 degrees.
The biomechanics men - Dr Marc Portus, Professor Bruce Elliott and Dr Paul Hurrion - used cameras shooting at 250 frames per second (ten times the speed of a TV camera) to illustrate phenomena such as adduction and hyper-extension, which can convince an observer watching with the naked eye that the bowler is chucking.
Research was also undertaken during the ICC Champions Trophy in England, where it was found that 13 of the 23 bowlers filmed straightened their arms more than the current permissible levels. Ramnaresh Sarwan, he of the fairly innocuous legspin, was the only man observed who didn't straighten his arm at all.
