It was a good single from Ben Stokes. That's what Dom Sibley needs because he's not a naturally aggressive player of spin, he doesn't seem to have too many options. Roston Chase must quite enjoy bowling at Sibley because he doesn't do too much different, it's very patient batting.

Dom Sibley was very slow setting off, Ben Stokes was perfectly in control. It was a little bit tighter than it should have been.

Is he be the answer long-term? Who knows. But he's showing application others have lacked in recent years.

Sibley has a slip, a leg-slip and a short-leg for company and eventually manages to drop the ball into a gap big enough for Stokes to call him through for a single.

There's a bit of a stutter before Sibley makes his ground.

Andy: I really like the look of Dom Sibley. An actual opener who wants to stick around and not give away his wicket! What a novelty! No doubt the moaners will complain he doesn’t score quick enough.

Stokes continues to walk down the pitch to Roach. If that's not a sign the light is fine then I don't know what is. Just a no-ball from the over.

A quiet start after tea.

The West Indies will look at the first hour before lunch and think that they've missed a trick. Their bowling wasn't very accurate.

Sibley survives another over but doesn't look like causing any damage. He plays a few practice strokes after the final ball and they looked pretty defensive too.

I've just backed Sibley, and don't want to contradict on myself, but he has to find a few more scoring shots off the spinner.

Who is complaining?

The Barbadian Murali - Roston Chase - is going to have another spell.

SCFCTom: I just don’t understand our media. We complain that we have no batsman who can hang in there and bat a long time. Now Dom Sibley is doing exactly that, he is being criticised for slow scoring and “sucking the life” out of the game. Unbelievable.

Mark Wood is munching on an apple on the boundary edge along with some of the other England players not playing in this game. Jack Leach is there too with his cap on backwards.

Kemar Roach starts with a maiden after tea.

The men in charge are happy. Kemar Roach is thrown the ball. Here come Ben Stokes and Dom Sibley.

We probably won't get a full session in because of the light but hopefully we get a fair chunk.

People at the ground say it is dark but the umpires are back out in the middle. The West Indies fielders are following them although the light meter is out.

There was about as much action in the final couple of overs before the break than in the previous 10.

Sibley could have been caught and Stokes launched a big six.

Not having it.

Unless there is a strange micro-climate making the cricket ground darker than it is a mile away across Salford Quays, it's not too dark to play cricket.

It's dark. The floodlights are casting four shadows off everyone in the middle and glinting off reflective surfaces. It's hard to see this day going the distance. On top of that, Windies skipper Jason Holder was having an animated chat with the umpires at tea. No clue as to what it was about.

It must be said it was slow going at times in that session. Zak Crawley was out from the very first ball after lunch and then Joe Root steadied things.

In the end, Root was out playing a loose shot for 23.

Ex-England spinner on BBC Test Match Special

The surface has done a bit. I thought it looked flat when they took the covers off this morning. It keeps everyone interested.

Thanks Amy.

The faffing with light meters has really annoyed me. I am currently sat about a mile away from Old Trafford in our office. We can see the football ground down the road from the cricket ground.

There is no way this light is too bad to play cricket in. It annoyed me so much I stood up and took a picture out of our office window to show you.

Get on with the game!

Right. I am done for the day.

I'm handing you over to Matthew Henry, who has a bee in his bonnet about the light situation at Old Trafford.

Dom Sibley calmly sees off the last ball and then strolls off for tea.

83 runs in that session, for the loss of two wickets.
