You'd have to say England have had the better of the conditions today. West Indies arrived with the dampness from yesterday. They haven't played some of the brightest cricket. They made some silly decisions with the bat.
Bairstow 21, Root 36
Shannon Gabriel sends down two leg-side wides and finishes with another short one that Jonny Bairstow pulls out to the man in the deep for a single.

It was short, it sat up for Joe Root, and he got enough on it. England are racing along.

In fairness, it's not a real job.

RE Jack Skelton's job, my girlfriend recently sensed I wasn't happy in my current role and asked what I would like to do instead; when I said write the live text commentary for cricket she said that wasn't a real job, to which I replied, "well maybe we should ask Jack Skelton!" She said she didn't know who that was. It was frosty.

Two of the previous three ODI partnerships for Root and Bairstow v West Indies have seen them put on a century stand (125, 18, 138*)
Target 213
Dre Russ does at least get through the rest of the over without conceding another run.

Andre Russell is really struggling. I understand his commitment but sometimes you have to be smart about it.
Image source, ReutersAndre Russell looks crocked here.
Not sure he'll be OK to bowl a second over.
Short and wide from Russell and Root carves it away through point for more runs.
Sheldon Cottrell sets off in his inimitable running style, legs and arms extended and pumping like he's marching.
It's quite a sight. Anyway he prevents the boundary and holds Root to three runs.
Dre Russ starts with a half volley and Joe Root square drives it four. Lovely shot, dreadful delivery.
Andre Russell is coming into the attack. West Indies need the kind of spell he had against Pakistan.
Will his body hold up? He's carrying more injuries alone than England have in total.
Need 167 more runs to win
Joe Root swivels Shannon Gabriel's first ball round the corner and picks up two as short fine leg makes a half-stop.
Root then cuts out to third man and scampers two. Superb running.
A wide on height and a single off the last as Root punches into the covers and there's a misfield.
Shannon 'The Archangel' Gabriel is on for his first bowl of the World Cup.
Bairstow 20, Root 19
Even when West Indies were running through Pakistan, Sir Curtly Ambrose was badgering them for bowling too many poor balls.
You can rightly imagine he's not at all happy here.

This is poor bowling.
Joe Root, down on one knee, holding the pose as the ball races through the covers for four.
Dreamy.
Another poor long hop from Oshane Thomas, mind.

Beautiful shot! West Indies bowlers are either too full, or too short. There's no middle ground.

Glorious.
