Jaker Ali's blistering unbeaten 72 highlighted a dominant Bangladesh effort as the visitors thrashed the West Indies by 80 runs in the third and final T20 International to sweep the series 3-0 at the Arnos Vale Stadium in St Vincent on Friday (Bangladesh time).

Benefiting from a huge reprieve when he thought he had been run out on 18, the attacking right-hander took heavy toll of an uninspired Caribbean team, belting six sixes and three fours off just 41 balls to pace his side to a challenging 189 for seven after skipper Litton Das opted to bat first.

In reply, the hosts were never in the hunt for a consolation victory, eventually bundled out for 109 off 16.4 overs.

"It's been quite a wonderful series for me, throughout the Test series, ODI and the T20I… I was just trying to take time and give time (at the crease). I know myself, if I go deep in the game then I will score some runs," Jaker said after the match.

Debutant opener Parvez Hossain Emon, playing in the absence of the injured Soumya Sarkar, set the tone for the Bangladesh innings with 39 off 21 balls before "Man of the Match" Jaker took over the show with a display typical of his uninhibited batting style.

However, it could all have been very different had the on-field run-out decision against him stood following a terrible mix-up with Shamim Hossain. A fuming Jaker, believing that a second run was always on, could not disguise his rage when Shamim opted to return to the striker's end and bowler Roston Chase effected the dismissal.

Yet even as he continued to vent his frustration in the dressing room, television replays showed he had made his ground at the striker's end just before his partner returned to safety, meaning that Shamim was the man eventually on his way back to the pavilion.

"(Run-out incident) I think that's a horrible mix-up. In the dressing room, I was just kicking myself, my bat, and everything around me. And suddenly the third umpire (fourth umpire) called me. And another run-out happened because of me. I was just kicking myself, and I was broke at that moment," he said.

"But Alhamdulillah (Praise to The Almighty) allowed me to play for my team. I have scored their runs too (Shamim and Mahedi)."

All was forgiven at the end of the innings, though, as Shamim was first to embrace his teammate after his power-hitting drained any enthusiasm left in a deflated West Indies side.
