Romario Shepherd looks frustrated as he gets one to rise up at Harry Brook and cramp him for room, but Brook still somehow manages to rock back and glove the ball over the wicketkeeper's head for four.

Good ball, good shot.

Not sure that Cariah did much wrong in that over but he’s still been monstered for 23 runs. Brook and Livingstone aren’t waiting for the last 10 overs. The slog has started early.

And again! Back-to-back sixes from Liam Livingstone as he hammers the ball over deep mid-wicket.

23 runs off that over in total. The best of the match so far.

Now Liam Livingstone is joining the party. He takes a hop, skip and jump down the track and carts the ball back over Yannic Cariah's head for another six.

That was a ludicrously brilliant six from Brook. To get that sweep fine enough to beat deep square leg had shades of Suryakumar Yadav.

This is Harry Brook's third ODI fifty in 13 matches. His highest score of 80 came against South Africa in January.

The answer to that question will be yes,

Harry Brook sweeps Yannic Cariah over square leg for six, before helping himself to a four through fine leg next ball.

On a horrible, multi-paced pitch, that is a very accomplished and composed 50 from Brook.

A single next ball brings up Harry Brook's half-century. A battling effort in tricky conditions from the Yorkshireman.

Will he now put the foot down in the final 13 overs?

That six from Harry Brook was England's first since the sixth over, which was also off Romario Shepherd's bowling.

That’s more like it. Too short from Shepherd and Brook has picked out the floodlight pylon.

Harry Brook was listening. He has seized onto a short delivery from Romario Shepherd and clobbers the ball over long-off for a massive six.

The longer England’s batters survive, the more difficult they make batting look. First it was Crawley who slowed to a glacial pace, and now Brook is struggling to get the ball off the square.

England have scored just 15 runs since Zak Crawley's departure for 48 in the 30th over.

There hasn't been a boundary for 31 balls.

Well bowled Gudakesh Motie. Just three singles from his final over means he ends with figures of 2-49.

Even though they have slowed down slightly if England continue at this rate they will still reach 272, which would be a defendable total on this pitch.

This is an important series for Liam Livingstone. He has played 23 ODIs but hasn't ever really nailed down his place.

During the World Cup, he played six matches and scored just 60 runs.

Ooh, another delivery holds up in the pitch, this time from Alzarri Joseph, and Harry Brook misses the ball as he opens the face outside off stump.

Another very tidy over from Joseph, with just the single off it.

England have scored just 10 runs from the last five overs. Their run rate has now dipped below five-and-a-half an over.

Joe Root who isn't part of this England squad has the best record of any overseas batter on this ground having scored 261 runs at an average of 65.25.

England need to be very careful here. It's important they don't get too greedy - anything over 275 is going to be very difficult for WI to get on this pitch.

This innings is starting to look and feel like some of the ones we saw at the World Cup, which is obviously not good.

Liam Livingstone is the next batter as West Indies eye a route through to England's tail.
