New Delhi, Aug. 5 -- Saim Ayub posted a half-century in a 138-run opening stand with Sahibzada Farhan and then took a key wicket as Pakitsan beat West Indies by 13 runs Sunday to clinch the Twenty20 cricket series 2-1.

Pakistan posted 189-4 and then bowled tightly enough to restrict West Indies to 176-6.

Pakistan's opening partnership ended when Farhan was out for 74 runs in the 17th over, his 53-ball innings finishing when he hit a low full-toss from Shamar Joseph (1-57) directly to Shai Hope at long-off.

Ayub continued until the last ball of the penultimate over of Pakistan's innings, when he hit a full ball from Jason Holder (1-34) to Sherfane Rutherford in the covers and was out for 66 from 49 deliveries.

West Indies raced to 33-0...
