Ellis Achong 1932. Achong is better known for playing cricket. He was mainly a bowler. His stock ball was left-arm orthodox spin (left-arm finger spin), but one of his variations was unorthodox left-arm spin. After bowling this variation to have Walter Robins stumped at Old Trafford in 1933, it is reputed that Robins said to the umpire, Joe Hardstaff Sr., "fancy being done by a bloody Chinaman". Learie Constantine is said to have replied: "Do you mean the bowler or the ball?" An unorthodox left-arm spin delivery (spinning from the off side to the leg side for a right-handed batsman) is known
Wrist spin manner. Additional spin many be put on the ball through two other means: the active pronation of the arm from an initially supinated position just before the ball is released, and the extension of the wrist at the moment of release. Both techniques increase the effect of the "cutting" mechanism. The slower a spin bowler delivers the ball, the more actively he must attempt to impart spin onto it in order to maintain the same rate of revolution. Although the biomechanical details of wrist spin are the same for right and left handed bowlers, such bowlers are often discussed separately,
