The gangling Khulna bowler returned career best figures in any form of cricket as he took seven for 17 in eight overs to prompt a collapse for the touring side who crashed to 227 all out in 46.1 overs after being 216 for five chasing 288 to win. The home team now lead the five-match series 2-1.

The second string Bangladesh side had earlier thrived on two splendid half centuries by opener Al-Shahriar (62) and Faisal Hossain (61 n.o) to amass 287 for 7 in the allotted 50 overs after captain Alok Kapali had decided to bat first.

But the Zimbabweans appeared unruffled by the huge task as openers Peit Rinke and Trevor Gripper smashed the two new ball bowlers Alamgir Kabir and Tareq Aziz Khan to all parts of the ground in their 99- run stand that came in just 14.4 overs. However, things changed with the introduction of Razzak who dismissed both openers by accepting return catches. Incidentally, both batsmen fell on 49.

Bowling a mixture of flat, fastish deliveries and occasional flighted ones, Razzak also accounted for number three Visumuzi Sibanda (9) as he finished his first six-over spell for 14 runs. Fellow Khulna man and left-arm slow bowler Manjarul Islam Rana aided him with two wickets.

Richard Sims and Stuart Matsikenyire briefly raised hopes for Phil Simmons' charges but Razzak came back to take four wickets for two runs in his second spell, which included the scalp of Matsikenyire (48) as Jamaluddin Babu pulled off a one-handed blinder at gully. Kapali ended the Zimbabwean chase when he castled number ten Jordan Nicolle.

In the morning, the A side's batting had set up the match. Al Shahriar made a long-awaited return to form with an uncharacteristically sedate knock that saw him play 92 balls before he was run out. Left-hander Faisal, who has been one of the new faces along with Razzaq to be called up for the Tigers' preliminary camp for the tour of the West Indies, continued to impress in his undefeated 67-ball innings that had four hits to the fence.

Skipper Kapali, coming off a ton in the previous match, contributed a 52-ball 33 while wicketkeeper Dhiman Gosh provided the flourish towards the end. The Bangla-desh under-19 wicketkeeper's 38 came off just 24 balls and featured four fours and a six.

The last two matches of the series will be held in Khulna on April 5 and 6.
