Chittagong: Bangladesh beat Ireland by 22 runs under the Duckworth-Lewis-Stern method in a rain-affected first of three T20 internationals between the sides.
Rony Talukdar struck a career-best 67 from 38 balls as the hosts posted 207-5 in 19.2 overs before rain ended their innings prematurely.
When play resumed, Ireland found themselves chasing a formidable target of 104 off eight overs.
Despite a brave effort, the tourists could only manage 81-5.
Gareth Delany top-scored for Ireland with an unbeaten 21 off 14 balls, ably assisted by Harry Tector (19) and stand-in skipper Paul Stirling (17).
Taskin Ahmed excelled with the ball, ending with figures of 4-16.
Stirling and Mark Adair combined for an opening wicket partnership of 32, but when the latter was bowled by Hasan Mahmud for 13, three further wickets fell in quick succession to leave Ireland 40-4.
Brief scores:
Bangladesh 207-5 (19.2 overs): Talukdar 67, Das 47; Young 2-45
Ireland 81-5 (8 overs): Delany 21*, Tector 19, Stirling 17; Taskin 4-16
