Bangladesh lost both their openers on day one, ending on 34 for two in reply to Ireland's 214, in the one-off Test match in Mirpur's Sher-e-Bangla National Cricket Stadium Tuesday.
The home side lost a wicket in the last ball of the day's play as experienced opener Tamim Iqbal got caught at slip off the bowling of Irish spinner Andy McBrine, which gave the psychological advantage to the visiting camp at close of day one.
Mark Adair bowled Nazmul Hossain Shanto for a golden duck in the very first over of the innings.
Tamim and Mominul Haque then formed a 32-run partnership and when things were looking good for Bangladesh, they suddenly lost the wicket of Tamim in the final delivery of the day which delighted the Ireland camp.
Mominul was unbeaten on 12 at the end of the day's play with Bangladesh trailing Ireland by 180 runs.
Earlier, left-arm spinner Taijul Islam claimed 5/58 to help bowl Ireland out for 214.
Harry Tector top-scored with 50 for the tourists, who otherwise struggled to build partnerships after electing to bat first.

Shoriful Islam struck early to trap opener Murray Commins for five before Ebadot Hossain and Taijul dismissed James McCollum (15) and Andy Balbirnie (16) respectively.
Tector, one of the six debutants for Ireland in their first Test since July 2019, put on 74 runs with Curtis Campher for the fourth wicket to steady the innings, rescuing the side from a precarious 48/3.
Mehedi Hasan Miraz cleaned Tector up to break the stand before Taijul made two quick strikes to dismiss Peter Moor (one) and Campher (34), derailing Ireland again.
Surprisingly Tigers skipper Shakib al Hasan bowled only three overs in the whole day although he was looking fit enough to bowl.
Cameos from Lorcan Tucker (37), McBrine (19) and Adair (32) took the visitors past the 200-run mark.
Taijul trapped Adair leg-before to complete his 11th five-wicket haul in Tests and Miraz wrapped up Ireland's innings in the next over to finish with 2/43.
Ireland have lost all three of their previous Tests since becoming a Full Member of the International Cricket Council in 2017.
