A superb display from Tamim Iqbal helped wraps up series win for Bangladesh. The left-handed opener also hit five fours in his 96-ball stay as Bangladesh passed Zimbabwe’s total of 188-6 with seven overs to spare.
Tamim put on 136 with Junaid Siddique (56 not out) for the second wicket.
The fourth match had been abandoned without a ball being bowled because of a wet outfield in Chittagong on Friday.
Tatenda Taibu (64) and Craig Ervine (46) had restored some respectability to the Zimbabwe innings with a stand of 95, but both fell to spinner Shakib Al Hasan (3-58).
