Many of my American friends are mystified by cricket: not just the rules, but the very mechanics of the game. They assume that bowling is like pitching, and can’t seem to understand that in cricket one is dealing with movement in the air (as in pitching) and movement “off the pich”, generated when the spinning ball bounces. The BBC have put up a series of brief video masterclasses on various cricket techniques; the one called Learn the basics of leg-spin is particularly good. Recommended.
