A thick edge from Joe Root against Wanindu Hasaranga but there's enough bat and angle behind it to help the ball run away for a couple of runs.

On Sri Lanka's batting, it is all very well for players to be out of form and understandably so with the lack of preparation. But two reverse sweeps on the first day of a Test?

I was just pondering Joe Root's hair - it looks better than that awful, Beckham-lite thing he was sporting in the summer but he's had quite the close crop. It's managed to make him look both old and young at the same time.

Joe Root has had a very savage haircut. I am told Ollie Robinson was the one who performed it this time.

John Petrie: I know he has had a dip in form, but when you watch Root bat you can see just how good he is. He always seems to have more time to play his shots.

There's 13 overs left in the day - and do you know, we might get them all in.

Thank everything for spinners who go about things as quickly as they can. The less faffing, the better.

Oh, close! Jonny Bairstow drives the ball straight back at Lasith Embuldeniya, who sticks his right hand up but ends up grasping at fresh air. Bairstow gets a couple of runs for his troubles but that wasn't too far away...

I don't think England will be able to believe the day they have had.

To have lost the toss and potentially have got into such a strong position, having played such little cricket. It really has been a bit of a dream day.

Jonny Bairstow gets in on the bounday act, leaning back to a short delivery from Wanindu Hasaranga and guiding it away through backward point for four.

Joe Root is the first batsman in the match to reach 30.

There's a stat.

Haven't these two played well? They have been busy and run between the wickets well. If a bad ball has come they have put it away.

Four! Joe Root hammers a sweep away off Lasith Embuldeniya and sends the crows that were gathering down at mid-wicket flying away.

A single from the final ball of the over brings up the 50 partnership beween this pair from 110 balls.

There is enough in the pitch for Sri Lanka's spinners. A couple of quick wickets and it could change quite quickly.

England are in the driving position. It has been a bit of a gift for them to be in this position.

Jonny Bairstow lunges out of his crease and is struck on the pad, but an optimistic appeal is waved away by umpire Dharmasena. This is nice, calm, patient cricket. Something we haven't seen an awful lot of today.

A thick outside edge from Jonny Bairstow as he shows his bat face to Lasith Embuldeniya but he's played it wih soft hands, and it rolls safely away from the slip fielder and out for a couple of runs.

England only trail by 76...

Gosh, I can't wait to have a nap.

It just for some reason didn't look right. But, Root has got away with one.

I don't think I'm allowed to tell you what Mickey Arthur shouted when he saw that review...

It didn't - but it's missing the stumps!

My word. The technology reckons that would have bit and bounced over middle stump. Not by much, mind, but still. A life for Joe Root.
