Former Pakistan spin wizard Saqlain Mushtaq was one of the finest bowlers of his generation. Saqlain is credited with the invention of the 'doosra' delivery, adding to a list of Pakistani innovations in cricket including the batsman's reverse-sweep and reverse swing bowling. The doosra, which means "the second one" in Urdu, turns from legside to offside -- the opposite direction to orthodox off breaks. From former India spinner Harbhajan Singh to former Mushtaq's compatriot, several spinners mastered the art of bowling the 'doosra'.
