Bangladesh can complete a tour whitewash of Zimbabwe in the second and final Twenty20 match on Sunday.
Having won the one-day series 3-0, Bangladesh took a 1-0 lead in the two-match T20 duel with a four-wicket win on Friday.
After putting Zimbabwe into bat, Bangladesh bowled the tourists out for 131 but were reduced to 80-5 in their subsequent run chase.
Zimbabwe's efforts with the ball proved in vain, however, as Bangladesh recovered to finish on 136-6.
The only bright spot for Zimbabwe was the form of Malcolm Waller with the bat, the right-hander top scoring with 68.
And Waller has called on Zimbabwe to improve with the bat as they aim to salvage a share of the series and end the tour with some small consolation.
He said: "In the next game, we need a lot more runs on the board and bowl well and have a good start and make things easier for ourselves."
Meanwhile Bangladesh captain Mashrafe Mortaza believes the game can be used as a measuring stick for his side ahead of the ICC World Twenty20 in March.
Mashrafe said: "This could be the last chance for us to see how some of new players react under pressure [in this format]."
Tamim Iqbal (31) and Mahmudullah (22) were the only Bangladesh players to score above 20 in the opening game in Mirpur.
The conditions at the Shere Bangla National Stadium are unlikely to be conducive to high-scoring in the second game, with 150 regarded as par on a surface on which the ball can keep low.
With their bowlers having produced a strong performance in the first match, Bangladesh should have plenty of faith in the attack to take advantage of a favourable pitch and complete a miserable tour for Zimbabwe.
