The hosts were restricted to 232 for eight with Darren Bravo leading the way with a half-century after Pakistan captain Misbah-ul-Haq won the toss and elected to field first.
Mohammad Irfan got the big scalp of Chris Gayle in the first over. That was the wicket they were looking for and Irfan had vindicated his captain’s decision.
In reply, Pakistan looked steady until the half-way mark, but lost wickets to hand the game to West Indies. The five match series is now level at 1-1.
