In restricting the hosts to 124 for nine, in reply to their total of 135 for seven, the tourists took the series 2-0 and moved up to second in the international rankings, behind Sri Lanka.
West Indies, the world T20 champions, dropped to fourth in what was yet another setback following hard on the heels of the 3-1 loss to the Pakistanis in the preceding One-day international series.
An unbeaten 46 by man-of-the-match Umar Akmal and 44 from opening batsman Ahmed Shehzad paced Pakistan to a total that was always going to be challenging on a slow, turning surface ideally suited to the sub-continental team.
Spinners Sunil Narine and Samuel Badree shared five wickets for the West Indies in what would prove to be an ominous precursor of the task the home side had to face in the quest to get a share of the honours.
After looking dead and buried at 17 for four, though, the Caribbean side fought back through the middle of their innings thanks to a battling top score of 35 from Dwayne Bravo and an aggressive 28 from Sunil Narine.
After his sensational debut in the first match on Saturday, when he took three wickets and then hit a six to win the match off the final ball, Zulfiqar was the deserving man of the series.
Meanwhile, the Pakistan Cricket Board (PCB) said they were “extremely concerned” over British media reports that their ODI series with the West Indies was being investigated for alleged suspicious betting patterns.
The Mail on Sunday raised the allegations over claims of wrongdoing in the series which Pakistan won 3-1 with one game tied.”The PCB is obviously extremely concerned at the recent allegations of fixing reported in the media with regard to the recently concluded ODI series between Pakistan and West Indies,” an official told cricinfo.com
“The PCB maintains zero tolerance towards corruption in the game, but investigations in this matter falls within the purview of the ICC’s Anti-Corruption and Security Unit.
“The PCB is in contact with the ICC on this issue and understands that the ICC will be issuing a media release soon.”
