An analysis of the bowling action of professional cricketers in the UK for four seasons between 1981 and 1991 shows there to be a significant association between handedness and bowling style (seam or spin bowling). Furthermore, there is a significantly higher number of left-handed spin bowlers than would be predicted from the general population, but not left-handed seam bowlers. As the technical differences between left- and right-handed orthodox spin bowlers are much greater than those between left- and right-handed seam bowlers, these data are consistent with the view that the over-representation of left-handed bowlers reported by Wood and Aggleton (1989) is due to strategic rather than neuropsychological factors.
