Babar and Rizwan are both being careful. Playing defensive shots off of Ahmed's googly.

Rizwan hits the ball into the deep behind backward square leg.

In his first spell Rehan Ahmed took 0-37 before lunch in five overs.

He has taken 1-19 in his second.

Here comes Joe Root.

Alex Hartley said earlier he's been the most consistent spinner in getting wickets. Can he work his magic? Duckett seems to have gone up to the dressing room to have his ankle assessed. He seemd to go over on it in the field earlier. Doesn't look too serious though.

Root bowls a short ball but Babar works it through the square leg for one.

I was fully expecting Babar to sweep but there's only singles in this over.

Millington: Let Ahmed go for as many runs as needed, being expensive isn't important right now, giving him the feel for Test cricket and facilitating his growth based on how important he can be for England going forward is.

It is very difficult to keep the run-rate down on a pitch likes this.

It doesn't stop there.

The teen races in but it loops up and is swept again, this time between fine leg and deep mid-wicket. Not to the boundary this time though. Duckett manages to get it before the ropes.

A couple of runs but that'll be enough for them.

Ahmed's last ball is a googly but Babar works it safely for a single.

Leach is in the attack.

Babar and Rizwan are two world class players here. We saw how incredible their partnerships were during the T20 World Cup. But can they mirror that here with the red ball?

Two boundaries in the over from Rizwan. It is a wide release and swept past the short leg fielder for four.

Babar is unbelievable. He is a run-making machine.

Thank you Mike!

Good morning all!

Rehan to Babar. Now this will be interesting.

He's got his first wicket and that'll settle his nerves so he will itching for many more now.

Babar won't let him settle. It's dragged down and thumped for four. Game on.

And with that I'll leave you in the capable hands of Aymen Babar.

I'm off to experience the delights of the BBC canteen. Might work those naans into my full English - just as England innovate on the field, I innovate with the breakfast.

Perhaps Jack Leach is over-excited from that wicket as he oversteps for a no ball.

Mohammad Rizwan is the new batter in, he gets off the mark from the final ball over the over - dropping low to sweep Leach hard to the boundary.

What a moment for Rehan Ahmed. It is a good one as well. Saud Shakeel has held England up in the series.

It is a moment Ahmed will never forget.

It was an excellent delivery. It spun sharply.

The wicket will do him the world of good. There was a little bit more flight.

Has Rehan Ahmed got his first Test wicket?

Has that carried?

Ollie Pope sprawls forward at short leg to Shakeel - is that Ahmed's first Test wicket.

The umpires send it upstairs!

Babar Azam is one of three Pakistani players who have made three half centuries in his first four Test innings.

It has been a nice, efficient innings from Babar. Untroubled.

Over-pitched from Ahmed, and Babar clouts him into mid-wicket. It's cut off but thatt's 50 up for Babar!
