In cricket, left-arm unorthodox spin – often known as slow left-arm chinaman and abbreviated to SLC – is a style of bowling. The bowler uses a wrist torsion action to spin the ball so that when it pitches it turns from off to leg for a right-handed batsman, i.e. from left to right from the bowler's perspective. The direction of turn is the same as that of a conventional right-handed off spin bowler, however, the ball will usually turn more sharply due to the spin being imparted predominantly by the wrist. Charlie 'Buck' Llewellyn, a South African all-rounder who played at the end of the 19th century, laid claim to inventing the delivery. Some chinaman bowlers occasionally bowl the mirror image of a leg-spinner's "googly" (or "wrong'un" in Australia), which turns in the opposite way in order to trick the batsman. In this instance the ball turns away from the batsman, as if the bowler were an orthodox left-arm spinner.
The chinaman style of bowling is very rare, as not only is it difficult to bowl accurately (in common with leg spin), but the turn into the right-handed batsman is seen as less dangerous than the turn away from the batsman generated by an orthodox left-arm spinner, so virtually all left-armers choose to bowl orthodox. On the other hand, the chinaman bowler does have some compensating advantages. He can impart more spin than the finger-spinner, generally yielding more turn and bounce (a factor in Johnny Wardle's decision to use this style on pitches outside England, whereas the orthodox style was more effective on damp English pitches). The LBW law allows for a favourable decision even when the ball has pitched outside off stump, whereas it does not similarly favour balls which pitch outside leg (a factor in George Tribe's decision to use this style). In addition, the wrist-spinner can bowl the googly and topspinner with a comparatively modest adjustment in technique, allowing a wider range of deliveries.
