Reverse Swing Emerges — Sarfraz, Imran and the Pakistani Revolution

Sarfraz Nawaz had been experimenting with the technique since the late 1970s and is generally credited as its inventor.

Imran Khan, on his return from injury in 1985, worked specifically with Wasim Akram on the mechanics of reverse swing.

The classical theory was that a cricket ball swings only when new and shiny. Pakistan's bowlers, conditioned to abrasive subcontinental pitches and rough outfields, discovered that an old ball with one side kept dry and shiny and the other roughed up could be made to swing in the opposite direction to the conventional in-swinger — fast, late and around the batsman's leg stump. Sarfraz Nawaz is widely credited as the inventor; Imran Khan refined and propagated the technique through the 1980s; Wasim Akram and Waqar Younis perfected it into a coordinated weapon by the end of the decade. The technique was viewed with suspicion by English and Australian players, who alleged ball-tampering, until eventually the wider game accepted reverse swing as a legitimate and dominant skill. By 1992, Pakistan's Wasim and Waqar would dismantle England in England with reverse swing — but the seed had been sown in the early 1980s in Karachi, Lahore and Faisalabad.

“I learned reverse swing from Sarfraz. I taught it to Wasim. That is the line.”

“We thought it was tampering. It wasn't. It was skill.”

By the early 1990s every Test attack in the world was trying to learn reverse swing.
