It pitches in line from around the wicket but it's sliding across and missing off stump. Hales was confident there and he was right to review it. 

Alex Hales is given out lbw to Kraigg Brathwaite but he reviews immediately.

Root throws the bat to Carter and edges down to third man for four more. He's now into the 70s. A thicker edge brings the Yorkshireman a couple more. Zero threat from West Indies. They are just getting through the overs. Nothing more.

That's absolute rubbish from Kraigg Brathwaite as the off-spinner comes on - halfway down the pitch and about a metre down the leg-side. You'd do well not to hit that for four and Joe Root doesn't miss out. The 150 partnership is up from 155 balls - the sequence per 50 has been 64-49-42.

From personal experience I think we get rid of bowlers too quickly. Now we're playing an ODI at home and we don't have a bowler who looks capable of even taking a wicket. You have to have the desire to bowl fast. That doesn't have anything to do with the pitches. 

Root belts Carter for another boundary as the partnership approaches 150. Nine off the over.

England are moving along smartly here. They'll be looking for 320 minimum. The problem with the West Indies bowling attack is bringing guys in and, when they get the opportunity, they are not taking wickets. I don't think we have enough bowlers that are penetrative enough to get wickets at this level, in terms of pace.

20 overs to go, nine wickets in hand and England are facing county cricket-standard bowling. All set up for carnage.

Nurse offers up a lame foll toss and Joe Root goes to his 21st ODI half-century with a reverse-sweep for four. This is routine for England. Inoffensive, ineffective bowling. 

Alex Hales has now got his strike-rate above one a ball - and a slog square of the wicket on the leg-side off Carter takes it higher still. The England opener now has 89 from 85 balls.

I think Hales may like a bit of Carter, he may line him up in the next few balls.

That's more like it from Hales, a reverse-sweep bringing him four off the opening delivery of Nurse's fourth over. And then he goes aerial again - very high over mid-wicket and he clears the rope for his third six of the innings. 150 up for England too.

Root has played quite interestingly in this series, he's not in an electric place. But he's dug in and he clearly seems comfortable to be able to adapt to the different needs of who's batting.

Jonathan Carter comes on, replacing Carlos Brathwaite. Three wickets in 19 previous ODIs for the medium-pacer isn't exactly frightening. Still, he's not giving much away in his opening over and England have to deal in singles again.

Thanks very much, Amy. England are in a great position here to really give it some hammer in the second half of the innings. 300 has to be the minimum target from this point. Ashley Nurse continues after his second over went for 13. The off-spinner reestablishes a degree of control - just three singles from that over.

And with that, I'll leave you with Alan Jewell to take you through to the end of England's innings. 

Alex Hales gets off strike and Joe Root calmly works a single as England reach the halfway point. I'm still not entirely sure how that ball managed to miss all three fielders - they were all charging towards mid-wicket and yet it dropped right in the middle of all of them.
