Pakistan kept faith with the same team which won the second match by 24 runs on Friday for a 2-0 lead. They won the first match by four wickets on Wednesday.
Pakistan were again forced to sit out Shoaib Akhtar who missed the first two matches due to a calf injury. Team manager Yawar Saeed said Akhtar has almost regained fitness but was not risked.
West Indies dropped wicket-keeper Carlton Baugh to bring Brendan Nash back in the team as their only change, handing Xavier Marshall wicket-keeper's duty.
