Batting first, opener Rahmanullah Gurbaz's 79 off 52 balls powered Afghanistan to a challenging 157-run target. The Afghan bowlers followed up the solid batting performance with an efficient bowling display to restrict the West Indies to 127/7.
Naveen-ul-Haq was the top wicket taker for the hosts with three scalps, which included the important wickets of captain Kieron Pollard and Jason Holder.
Gulbadin Naib got the big wicket of Shai Hope, who scored 52 off 46 balls. Mujeeb Ur Rahman, Karim Janat and captain Rashid Khan all got a wicket each. Mujeeb was especially effective in starving the Windies of runs, giving away just nine in three overs.
Earlier, it was the Afghanistan middle order that gave Gurbaz the necessary support as the top order batsmen were dismissed cheaply by Sheldon Cottrell and Pollard. Gurbaz hit six fours and five sixes in his innings which helped seal an impressive comeback from Afghanistan who lost the preceding ODI series 0-3 besides going down in the first T20I.
Brief scores: Afghanistan 156/8 in 20 overs (Rahmanullah Gurbaz 79, Asghar Afghan 24; Keemo Paul 2/26) vs West Indies 127/7 in 20 overs (Shai Hope 52, Evin Lewis 24; Naveen-ul-Haq 3/24)
