A more disciplined bowling performance from Zimbabwe induced a Bangladesh batting meltdown on Friday, as the visitors lost five wickets for the addition of just 39 runs on the third morning of the first Test at Harare Sports Club.
Having bowled poorly on the second evening in allowing Bangladesh to race to an overnight total of 95 for one, Zimbabwe's pacemen tightened up in the first session on Friday and the rewards followed as Bangladesh collapsed to 134 for six at lunch.
Kyle Jarvis spearheaded the attack after a wayward Thursday in which he conceded 39 runs from eight overs, bowling six overs for just one run to heap pressure on the Bangladeshi batsmen.
It paid off at the other end when Keegan Meth grabbed his first two wickets in Test cricket, trapping Jahurul Islam lbw for 43 and bowling Mahmudullah off a bottom edge.
Shingirai Masakadza backed that up with three wickets of his own, including two in the same over when Shakib Al Hasan edged to gully and then Mohammad Ashraful threw his wicket away to depart for 38.
Masakadza also struck on the stroke of lunch, dismissing Bangladesh captain Mushfiq Rahim lbw for seven to leave Bangladesh trailing by 255 runs with just four first-innings wickets remaining.
