Young leg spinner Shadab Khan (4-14) gave another match-winning bowling performance and Hasan Ali held his nerve for Pakistan to sneak a three-run victory over the West Indies to take the series.
West Indies had the game under control at 60-1 but threw it away with some curious batting in the closing overs.
Earlier, Pakistan struggled against the twin spin threat of Narine and Samuel Badree. Their ninth-wicket pair of Wahab Riaz and Shadab put on 36 quickfire runs off the final four overs to get Pakistan to 132.
Pakistan 132 (Malik 28, Narine 3-22, Brathwaite 3-37) beat West Indies 129 for 8 (Samuels 44, Shadab 4-14) by three runs.
