Like in the first T20I on Saturday, Zimbabwe captain Craig Ervine decided to bat first after winning the toss against Bangladesh in the second game in Harare.
However, the hosts persisted with the same XI that handed Bangladesh a 17-run defeat to help Zimbabwe go 1-0 up in the series.
Only once have Bangladesh won a T20I series after losing the first game, with Sunday being a must-win for them to avoid defeat in the three-match series.
