Though, After inventing the reverse swing and reintroducing leg-break bowling in international cricket, Pakistan cricket went on to formulate yet another unorthodox delivery: The doosra.
Uunlike the reverse swing, this name was coined by its main inventor: Saqlain Mushtaq.
Saqlain was inducted into the team by Wasim Akram in 1995. By 1996, he was bowling a delivery that was technically supposed to come in as an off-break (to a right handed batsman), but instead would straighten up and then go the other way. It would confuse the batsmen because it was always bowled without much change being applied to the bowling action. Between 1996 and 2002, only Saqlain was bowling it and it was simply called his ‘mystery ball.'
