In pursuit of 198 at Dhaka, the hosts could only go as far as 179 for 1 despite fifties from Tamim Iqbal and Mahmudullah.
20 overs: Bangladesh 179 for 1 West Indies win by 18 runs. Great efforts from Tamim Iqbal (88 off 61 balls) and Mahmudullah (64 off 48 balls) but the target was way too big for them. Their unbeaten partnership of 132 runs goes in vain. Big kudos to Marlon Samuels whose 85 off 43 balls have made all the difference. With this match, the Caribbean team's tour to Bangladesh comes to an end. It's been a mixed one. They won both the Tests but they saw a 3-2 defeat in the ODIs. That's it from us. See you soon.
15th over: Bangladesh 119 for 1 Bangladesh need quick runs to have any chance. Tamim Iqbal (56) has completed his third T20 fifty and Mahmudullah also looks solid on 38, but quick runs are needed with the asking rate creeping towards 15. Remember they need 198 to win this contest.
10th over: Bangladesh 87 for 1 It's been a bit quiet but they are still in the hunt. Tamim Iqbal (44 not out) holds the key for the hosts. Mahmudullah (18) is keeping him good company. Both take their partnership to 40.
5th over: Bangladesh 49 for 1 There is first wicket for the Windies. It's the dangerous Anamul Haque who goes for 22 as he tries to hit Kemar Roach's short delivery out of the park. Miscues it and Darren Sammy takes the simplest of catches at mid-off. Mahmudullah joins Tamim Iqbal, who is on 27.
3rd over: Bangladesh 43 for 0 Just the start Bangladesh needed. Tamim Iqbal (23) and Anamul Haque (20) have torn into the Bangladeshi bowling. Darren Sammy, Kemar Roach and Andre Russell all leak runs.
20th over: West Indies 197 for 4 It's a huge total. Thanks to Marlon Samuels who makes an unbeaten 85 off 43 balls with the help of nine sixes and three boundaries. In the last over bowled by Rubel Hossain, Samuels hits four sixes and a four to close out the Caribbean innings with a flourish. Lendl Simmons gave Samuels good company with 18 off 12 balls, with both making 76 runs off 32 balls. Top stuff.
15th over: West Indies 122 for 4 Kieron Pollard's brief stay at the crease comes to an end as he loses his stumps while trying to hit Ziaur Rahman out of the park. He made 15 off nine balls. Meanwhile, Marlon Samuels continues solidity at the other end on 27. Lendl Simmons is the new batsman and is off the mark off the first ball.
12th over: West Indies 96 for 3 Darren Bravo's attacking innings comes to an end as he gets stumped off the bowling of young spinner Sohag Gazi for 41. The devastating Kieron Pollard has joined Marlon Samules, who is unbeaten on 23 with the help of two big sixes.
10th over: West Indies 81 for 2 Darren Bravo (39) has taken the scoring responsibility following the departure of Dwayne Smith. Has picked up two sixes off spinners Abdur Razzak and Mahmudullah. Marlon Samuels (10) is a bit circumspect at the other end. However, he's also got a six to his name off Razzak. Both batsmen have taken their partnership to 51. Good recovery by the tourists.
5th over: West Indies 34 for 2 Rubel Hossain is having a ball out there. This time he cleans up the dangerous Dwayne Smith for 24. The tourists are in a spot of bother. Marlon Samuels has been joined by the elegant Darren Bravo at the crease.
3rd over: West Indies 25 for 1 Chris Gayle's poor run continues as Rubel Hossain cleans him up for six. Meanwhile, Dwayne Smith has played some really good shots at the other end. He is unbeaten on 19 off 11 balls with the help of two boundaries and one gigantic six.
