Ireland suffered a loss in their first T20 international against Bangladesh after falling to a 22-run defeat on the Duckworth-Lewis-Stern method.A hefty rain delay cut the Bangladesh innings short by four balls as they finished on 207 for five and Ireland scrambled to chase a giant target of 104 in eight overs as set by DLS.Bangladesh's top order produced a fine display to prop them up with Litton Das scoring 47 and Rony Talukdar smashing 67 off 38 balls before being bowled by Graham Hume.Shamim Hossain made a decent cameo with 30 runs, but play was brought to a halt in the final over due to rain, leaving captain Shakib Al Hasan unbeaten on 20 alongside Mehidy Hasan on four.Ross Adair and captain Paul Stirling made a strong start to the Irish chase, scoring 32 from the first two overs but the wickets soon tumbled for the visitors as Adair was swiftly bowled by Hasan Mahmud in the third over.Any chance of an unlikely comeback was then shattered by Taskin Ahmed, who took three wickets in the fourth over to dismiss Lorcan Tucker, Stirling and George Dockrell before taking the wicket of Harry Tector in the final over as Ireland were restricted to 81 for five.
