Bangladesh beat Ireland by 22 runs in the rain-affected first T20 in Chattogram Sunday.

Under the Duckworth-Lewis-Stern method, Ireland's target was revised to 104 runs in eight overs, but they could only manage to score 81 for five wickets, with Taskin Ahmed registering a career-best 4-16.

Ireland, who scored 18 and 14 runs off the first two overs bowled by Nasum Ahmed and Mustafizur Rahman respectively, lost their first wicket in the third over when Hasan Mahmud removed Ross Adair for 13.

Taskin struck thrice in the next over, ripping through Ireland's middle order.

After another 40-minute delay, the match restarted with a revised target for Ireland.
