Bangladesh scored 52 runs for 2 wickets in 8 overs in their third game of the Super 12 at the Twenty20 World Cup at Brisbane's Gabba ground on Sunday against Zimbabwe.
Opener Najmul Hossain Shanto scored 27 runs off 25 balls while another opener Soumya Sarkar out after scoring 0 runs from 2 balls.
Earlier, Bangladesh captain Shakib Al Hasan won the toss and chose to bat first.
Bangladeshi players are under pressure as they have been defeated by South Africa in the last match in Sydney while Ervine's are eyeing an unlikely tilt at a semi-final spot as his team defeated favourite Pakistan.
Zimbabwe's form is as good as their fighting spirit, and the way they defended the 130 against Pakistan was proof.
Bangladesh squad: Soumya Sarkar, Najmul Shanto, Liton Das, Shakib Al Hasan (capt), Afif Hossain, Yasir Ali, Nurul Hasan, Mossadek Hossain, Taskin Ahmed, Mustafizur Rahman, Hasan Mahmud.
