Mehedi's first spell in Test cricket comes to an end. Not a bad start from the young un, who bowled 10 overs and took 2-13. There is no respite for England from the spin, though, as Taijul Islam brings some left-arm off-spin to proceedings. He starts with a maiden.

Ever-reactive to the glare of a camera, the home crowd are out of their seats and bouncing around. They've got plenty to cheer as well. Their side are well on top. This is a better over from Kamrul Islam Rabbi, who finds good line to keep England to two singles.

No rest for Mehedi, who remains economical but is handled well by Moeen. These two are doing a decent job of rebuilding the innings. But on a turner like this there is no room to relax.

What I'm hoping today is that England are pro-active with changing the batting order, moving Bairstow up. You need to break it up with left and right handers and also that they are pro-active with moving their feet and getting that momentum.

Slip, gully and short-leg in for Kamrul, who continues despite his loose last over. Moeen opens up for the first time, latching on to a full ball to drive through cover. Classic Ali.

He misjudges the penultimate ball, though, ducking and turning his head to a short ball that doesn't bounce and is a few centimeters away from clocking him in the temple.

Mehedi has the makings of the perfect spinner, he gets side-on and through his action, but the key for me is the revs on the ball. England have got some work to do.

Mehedi restores order for Bangladesh with another tight over. Root plays with authority, Moeen looks very uncertain. The latter offers a tentative poke at the last ball, which spins past his bat. It is not easy as a left-hander in this situation.

We're set up for a brilliant Test match. I'm not sure how far into the five days it will go.

Ooooh, England have just got away with one. Had Bangladesh reviewed that Moeen lbw he would have been out. It pitched in line and would have clocked leg stump. The home side keep England guessing by returning to the slingy seam of Kamrul. It is a mistake. Root fills his boots, flicking one off his legs for four before driving beautifully through cover for another. Root, as is so often the case, is making this look easy while everyone else struggles.

Si Lomas: First thoughts on this pitch are it could be a 2 and a half day Test match, absolute bunsen burner.

After drinks (an absolute necessity in this heat), Mehedi continues his spin assault and prompts a huge appeal against Moeen, aho is caught on the pad sweeping. The umpire shakes his head. Looked leg side.

The over-rate is good which will be needed because I can't see them going on much after five this afternoon. After five yesterday it was very dimpsey.

Shakib keeps up the pressure, although his fielder don't help him out as Mushfiqur and his slip fielder both assume each other are catching a throw to the wicket, with the ball splitting them for an overthrow - the only run of the over.

Sounds impressive. I think.

What a debut this has already been for 18-year-old Mehedi Hasan Miraz. He is landing it well, turning it sharply and giving England all sort of problems. Root hooks one round the corner to get three more runs. 

Another salvage job, Rooty? He goes on the counter-attack, dropping to one knee and sweeping Shakib powerfully for four. He follows it up with a pull for another boundary. It is the right approach. England can't just retreat and dig in. Moeen Ali is the new man.
