Imad picked up five wickets for only 14 runs, becoming only the second Pakistani bowler and first spinner to do so.
At one point, West Indies were reduced to 48-8 but a partnership of 66 runs between Dwayne Bravo and Jerome Taylor gave WI total some respectability.
This was the largest 9th wicket partnership in a T20I match. Previous was 63 by Pakistan’s Sohail Tanvir and Saeed Ajmal vs Sri Lanka.
Earlier, Pakistan captain Sarfraz Ahmed won the toss and sent West Indies into bat.
“Dew will be a factor because of humidity, so we want to chase,” said the Pakistan T20 captain after winning the toss.
Pakistan rested Mohammad Amir from the side which beat England in the only Twenty20 in Manchester earlier this month, after the fast bowler joined the team late because of his wedding on Tuesday.
Amir’s place went to left-arm spinning all-rounder Mohammad Nawaz.
Middle-order batsman Umar Akmal also made a comeback after being overlooked for the England tour. He replaced Mohammad Rizwan from the Machester side.
“We’re excited. The morale within the group is high. Our white-ball cricket is getting better. We’ve been playing T20 cricket back home. Mohammad Amir is out, Mohammad Nawaz is in. Umar Akmal makes a comeback.”
West Indies gave a Twenty20 debut to wicket-keeper batsman Nicholas Pooran.
The second match will also be played in Dubai on Saturday while the third is in Abu Dhabi on Tuesday.
