The inswinging yorker, of the kind Waqar Younis hurled, is one of cricket’s most aah-inspiring sights. As it leaves a bowler’s hand, it seems the ball will harmlessly reach first or second slip. But as it traverses the 18 yards in the air to reach the other end of the pitch, something happens: it curves in menacingly towards the batsman, leaving him scampering around trying to prevent the ball from thudding into his pads or knocking down the stumps. Good batsmen know how to defend it or work it away; bad ones end up flummoxing even the wicket-keeper.
