South African cricketer, Johan Botha, who also plays for Adelaide Strikers, has approved the biomechanical test of his bowling action and is able to continue playing in CA Tournaments, Cricket Australia says on Wednesday.
Johan Botha was cited by umpires Simon Fry, Michael Graeme-Smith and Geoff Joshua in the RYOBI CUP match between South Australia and Victoria at Bankstown Oval on October 4. After the report, he was needed to undergo biomechanical screening of his action at the Australian Institute of Sport in Canberra last Wednesday.
The test, performed under the CA and International Cricket Council testing methods, needed Johan Botha to bowl 6 balls from each of the deliveries in his repertoire; an off-spinner, quicker ball and flicker ball. The testing discovered that Botha`s bowling action for all deliveries is under, or equal to, the permitted elbow extension of 15 levels, with an average extension of 9 degrees. Had any delivery in those 18 balls been considered against the law, Botha would’ve failed the testing.
His bowling action was captured by a 20 camera motion test system sampling at 250 fps, allowing for the 3D dimension of human movement.
