Pakistan captain Babar Azam will be aiming for a T20 series clean sweep and a shot at the No 1 ranking for batsmen when his team take on Zimbabwe in the third and final match of the series on Tuesday. Pakistan have taken an unassailable 2-0 lead following wins by six and eight wickets in the first two games in Rawalpindi. The hosts will be wary of taking it too lightly in the third match of the encounter as they had lost the dead rubber of the preceding ODI series via Super Over. Captain Azam will also have a personal milestone on his radar. The right-hand batsman lost the No 1 ranking for T20 batsmen earlier in the year to England's Dawid Malan and will be aiming to reclaim it. He made match-winning contributions of 82 and 51 in the first two matches and another big effort should help the 26-year-old get close to top spot. Malan currently leads the charts with 877 points with Azam close behind on 869. Pakistan will also be buoyed by the performance of leg-spinner Usman Qadir. The 27-year-old leggie, son of the late spin great Abdul Qadir, picked up 3-23 in the second match and impressed experts with his control and variations. "It is nice when young players perform," Azam after the second T20. "I played my early cricket with Usman so it was good to see him bowl like that. Overall, it's a good show by some talented players."
