Bangladesh captain Shakib Al Hasan took five wickets as Ireland were beaten by 77 runs in their second Twenty20 international in Chattogram, giving the hosts an unassailable 2-0 series lead.Chasing 203 in a match reduced to 17 overs a side following a rain-delayed start, the tourists lost skipper Paul Stirling to the opening delivery from Taskin Ahmed.Shakib (five for 22) then took the scalps of Lorcan Tucker, Ross Adair, Gareth Delany, George Dockrell and Harry Tector as Ireland stuttered to 43 for six, before eventually finishing on 125 for nine.The greatest resistance came from Curtis Campher, who hit 50 before becoming the third and final victim of Taskin.Bangladesh, having been inserted to bat, had earlier posted 202 for three, with Litton Das contributing 83 and Rony Talukdar 44 – that pair putting together an opening stand of 124 – while Shakib made 38 not out.The third and final T20 of the series takes place at Zohur Ahmed Chowdury Stadium on Friday.
