I am sure that Ireland actually got lucky in this match. Because if the match was played till the end they would have lost. But at the same time, I will also say that the performance from Bangladesh was not good as well. Against a weaker opponent like Ireland, they should have scored at least 280. And that's regardless of the conditions. Of course, Bangladesh was not able to even reach 250. I think this type of performance is not going to cut it when they will be playing in the world cup.
I hope Bangladesh will be able to perform well in the world cup considering that they will play at least 9 matches in the world cup. So they will have a good chance of qualifying. The captaincy does look a little weird but I think he was saving the spin bowlers for the middle overs.
Today's first ODI match has been abandoned due to rain, but I will focus more on the fact that Bangladesh team's batting performance has been very poor today rather than calling Ireland team lucky in today's match. If we follow the scoreboard we can see that among the Bangladeshi opening batsmen Tamim Iqbal and Liton Das both got out very early and Liton Das hit the golden duck.
sourceI was very worried that Bangladesh would not be able to get a good run in today's match due to the loss of big wickets, but anyway Mushfiqur Rahim among the seniors and batsman Nazmul Hossain Shanto among the young stars along with a few runs of others enabled Bangladesh to set a target.
However, I have the same thought as you that as a team, Bangladesh is much stronger than the Ireland team, so the performance of Bangladesh has not been very good. And I see today's performance as an indication that the Ireland team may be able to put up a strong performance going forward.
