Pakistan held off a desperate late surge by the West Indies to take the second and final Twenty20 international by 11 runs at the Arnos Vale Stadium in St Vincent on Sunday.
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.
"It was a tough tour and credit must be given to everyone associated with the squad for the success that we have enjoyed here," said a delighted Pakistan captain Mohammad Hafeez, who also played a key role with the ball in dismissing the dangerous but out-of-form Chris Gayle cheaply for the second time in two days.
Brief scores: Pak 135/7 (A Shehzad 44, U Akmal 46no; Narine 3/26) bt WI 124/9 (Dwayne Bravo 35, Narine 28) by 11 runs, win series 2-0.
