Dhaka, Nov. 27 -- Bangladesh slumped to a 39-run defeat in the opening T20, undone by the Tector brothers' clean striking and a disciplined Irish attack that held its nerve through heavy dew.

The Tigers, now on a four-match T20I losing streak, never recovered from a disastrous start to their chase of Ireland's 181 in Chattogram on Tuesday.

Ireland's innings was bookended by the Tector brothers. Tim's explosive 19-ball 32 launched them forward after Paul Stirling's early fours, and Harry's unbeaten 69 off 45 balls, laced with five sixes, powered them to a commanding finish.

But the match turned decisively during Bangladesh's chase, when the Irish bowlers attacked early and never let go.

The slide began immediately.
