3.06pm Mahmudullah calls his players in. Bangladesh have declared. Mushfiqur walks off acknowledging the crowd's cheers. Top innings from the little man. Holds the record for most Test double tons by a wicketkeeper, and the highest individual score by a Bnagladesh player. Bangladesh rack up 522. And to think they were 26 for 3 at one point. Mominul Haque was dropped on 9 yesterday. Had that catch been taken, this innings could have panned out very differently. But such is Test cricket. Lapses don't go unpunished so easily, and Zimbabwe have learned that the hard way. Big turn on offer, the cracks will start opening up given time. Zimbabwe must be completely deflated after nearly two days on the field. Can Bangladesh prey on that?

This is Bangladesh's highest Test score, crosses Shakib's 217 v New Zealand in Wellington in 2017. Mushfiqur had made 159 in the same innings.

Having already crossed Aminul Islam's 535 minutes earlier in the session, Mushfiqur Rahim now has also crossed Mohammad Ashraful's 417 balls to be at the crease for the longest time for Bangladesh (in terms of minutes and balls).

Waqar Durrani: "How about Jim Laker 19 wickets in a Test, would have wished 20 instead."

Jez: "And talking of Sanga, he also had an undefeated 199, which was followed by 192 in the next game."

Muhammed: "Remember, Sachin 194* when India declares the innings"
