Pakistan invented reverse swing in the 1960s. That was a long time ago. It was, unlike the wrong’un, not mastered for a long time, and took a decade to go from the Lahore Gymkhana to the Melbourne Cricket Ground (MCG) in 1978-79. But when it did, it changed cricket.
Thirty seven years ago...
Thirty two Tests into his career, Sarfraz Nawaz had only two five wicket hauls and, much like his nation, he had yet to make much of an impact on world cricket.
When he came back on, Australia were 305/5, cruising towards the monstrous 382 fourth innings chase. The second new ball was old, and Sarfraz started swinging this old ball violently.
He bowled Allan Border, Graeme Wood caught behind next ball, Peter Sleep was clean bowled, Kim Hughes was out soon.
Next over, Wayne Clark was bowled playing back to a ball he couldn't understand.
Then, a no ball, one run, and Rodney Hogg was LBW.
When Alan Hurst wasn't out first ball, the crowd cheered. Next ball, Hurst was caught behind.
Australia were now 310/10. Sarfraz had 2/85 but now he had 9/86. This number currently adorns one of the walls of the MCG as part of an art installment.
Most of the Australian batsmen had helmets. They were prepared for Imran Khan's scary pace. They would survive that.
At the other end, a man who bowled as if his hip needed to be replaced shuffled in with a sideways action and bowled just above medium pace.
