Saqlain Mushtaq made his Pakistan debut in September 1995, aged 18. He was an orthodox off-spinner with a fast arm and a strong wrist. Within a year he had developed a variation that turned the wrong way — using a flick of the wrist and middle finger that produced an action almost indistinguishable from his stock off-break. Moin Khan, standing up to the stumps, would call out to him from behind: 'Doosra!' (the other one). The label stuck. Saqlain produced devastating ODI figures with the doosra — 5/29 against South Africa in Lahore, 5/35 against Bangladesh, 4/12 against India. He took 20-plus ODI five-fers in his career, more than any other off-spinner. The flip side: as the doosra spread (Muralitharan adopted it; Harbhajan Singh and Saeed Ajmal would later) the ICC's chucking laws came under permanent stress. Saqlain's own action was tested but never deemed illegal under the post-2004 regime that allowed 15 degrees of arm extension.
