Off-spinner Saeed Ajmal took his fourth five-wicket haul in tests as Pakistan completed a facile nine-wicket win within four days in the second test against Sri Lanka on Saturday to take a 1-0 lead in the three-match series. Needing 94 for victory, opener Mohammad Hafeez remained unbeaten after scoring a quickfire 59 and knocked off the runs with Azhar Ali (29) after Pakistan lost Taufeeq Umar early.
