Cricket is an unpredictable game, especially when you’re a swing bowler

I spent something over twenty years struggling to make the ball curl in the air. It was just about the only thing in cricket I could do. I found out pretty early on that I couldn’t bowl fast enough to bother anyone with pace, but I could learn how to move the ball sideways, so I worked on that. It was work, too – I spent lots endless time in the nets experimenting with different ways to make the ball change direction over 22 yards, so much so that I remember one frustrated batsman in the nets shouting at me, “can’t you bowl just one that just goes straight?”

These experiments never took me much beyond “conventional” swing.
