Cook 153*; Root 136
Cook & Root add 248 from 39-2
Malan 28* - dropped on 2 at slip
Debutant Stoneman 8, Westley 8
Inaugural day-night Test in England
First match of three-Test series
You've been tweeting and texting away about pink balls, whether lunch should be called lunch and England openers. Stoneman may not have shone this morning, but Cook did what he does best. The ex-England captain very rarely looked troubled as he scored his 56th Test half-century.

The pink ball, modelled by Ebony Rainford-Brent. The consensus is it's done a bit, but that any movement that might have been on offer has been negated by too much loose West Indies bowling.

Here's one for you. After Stoneman is axed I know an established Test player who's opened in county cricket and is a pretty decent bowler - Chris Woakes to open the batting for England!

What a review this was from Windies captain Jason Holder. I was pretty sure this was out at first glance. Although, like many of you, I have struggled to see this pink ball at times! Tom Westley played across the line and was hit low on the pad.

I'm all for a knee jerk reaction - So Root to open for Stoneman (when he continues to fail), Westley to remain (looks Test capable), then bump everyone up to accommodate Woakes at eight - then you have a decent looking team.

The more openers England go through, the greater the pressure on the next man coming in. Surrey's Mark Stoneman had hit two solid boundaries - but a loose shot, combined with a cracking delivery from Roach, and he was making his way back to the dressing room.

There's been nothing out of the ordinary; it was like a normal day's cricket.
Is it 23 November 2006? Are we back at the Gabba in Brisbane? Kemar Roach did his best Steve Harmison impression by sending down this widest of wides.

Cheers Amy.
This day-night malarky is all very strange. But it's given us lots to talk about. Right then, let's spend the 'lunch' break by taking a look back at some clips from today.
These new times have messed up my eating habits. Anyway, here's a quick reminder of the timings for the rest of the day, before I leave you with Kal Sajad for the next few hours.
In a bit!

Stop giving away easy boundaries - that's the key. West Indies bowled some decent deliveries in between but they eased the pressure. They need to look at that for the next session.
Cook 50, Root 40
Root works a leisurely single, and that'll be lunch. Or dinner. It's definitely dinner.
That's not a bad start for either side, really - the West Indies got the ball to move a touch this morning to take those two wickets, before Root and Cook steadied things for England.

Cook is certainly playing well. He's served England for many years with distinction. He's got a lot still to contribute.
Eng 107-2
It's time for the traditional spinner's over before lunch - here's offie Roston Chase. He comes around the wicket to Cook, just a smidgen of turn on offer as Cook ignores the first three deliveries. Chase spears the ball a bit wider, Cook drives - and a misfield at mid-wicket allows him to bring up his fifty! He raises his bat to the crowd while the fielder, quite wisely, hides his face in his hands.

I've enjoyed this from Anthony about the science behind the pink ball. You lot put me to shame.
Anthony England: The pink shine is a resin coating, the colour isn't impregnated into the leather. Sounds like an old pink ball is going to be difficult to see under the lights. A new one, with its plastic sheen, not so bad.
It's only going to get worse then if the ball darkens/dulls any more with wear, and doesn't reflect the lights well. The colour doesn't go deep - that's the key problem I reckon. The science isn't quite right for the job. It's all in the chemistry.

Four! That's a good old-fashioned half-volley from Kemar Roach, and Cook has thrashed it pleasingly through the covers. A single takes Cook to 49, before Root has to thrash his bat down on a yorker to spare his toes - and his stumps - from taking a bruising. Root wanders to short leg to have a quick word with himself, before he gets another full delivery which this time he hoicks to the boundary.

To have scored 20 boundaries by the 25th over is just too much. West Indies are guilty of over pitching it and giving away the boundaries.
Alzarri Joseph strays onto Joe Root's legs and again, another whirl of the pad goes racing away to the boundary. It's a quick outfield for sure. And again! Root goes through the off-side this time, letting the ball take the outside edge and go trailing away. A short ball comes Root's way but again, it's hip height, and it's very easy for the England captain to jab his bat down on it.
