CHITTAGONG: Bangladesh won their five-match one-day international cricket series against fellow minnows Zimbabwe in style after beating the visitors by six wickets in the fourth match here today. The visitors were shot out to one-day international cricket's fifth lowest total, setting the hosts an easy target of 45 to seal the series 3-1 before Thursday's final match. In reply, Bangladesh overcame some moments of panic, losing four wickets in five runs after the openers added 33 runs in 6.3 overs, before cruising home to a well-deserved victory. The visitors lost their four top batsmen for eight runs, due largely to some innocuous shots on a wicket that was forecast to be a batting paradise. All-rounder Malcolm Waller (13) tried to build the innings with Stuart Matsikenyeri (11), but once he lofted a catch at cover-point off Bangladeshi captain Shakib Al Hasan, Zimbabwe's innings folded up for just 44 in 24.5 overs. Shakib was the wrecker in-chief, picking up three wickets and conceding just eight runs in 6.5 overs. Left-arm spinner Enamul Haque got three wickets. But it was the pace-spin opening attack of Nazmul Hossain and Abdur Razzak which triggered the collapse, both grabbing two wickets each while giving away only 10 runs apiece. Nazmul was adjudged man of the match for picking the heavyweight wickets of Masakadza and Charles Coventry and the brilliant catch that sent back Waller. "I just tried to bowl straighter and stump to stump," said Nazmul.
