Root, promoted to open in absence of injured Roy, becomes first England batsman to score three WC hundreds
Morgan (back) & Roy (hamstring) both injured and don't bat in England's run chase
Windies bowled out for 212 in 44.4 overs - Pooran 63, Wood 3-18, Archer 3-30
Russell and Gayle were both dropped - England have now dropped as many catches as Pakistan in this WC (8)
Shimron Hetmyer has gone for the floppy hat now. It's a strong look.
That's not quite so nice though, Hetmyer having an awful hoick at Adil Rashid as he tries to sweep, before he thumps the last ball of the over towards Eoin Morgan at cover. Hetmyer shows his annoyance as he swings and misses at yet another Rashid wrong 'un.
Pooran 43, Hetmyer 37
Full from Joe Root and Nicholas Pooran, a little awkwardly, shuffles the ball off his pads and into the off side.
Just two runs from the over. Tidy.

I think this is good from Eoin Morgan, to get the ball spinning away from the left-hander.
Shimron Hetmyer is batting without a cap. No helmet, no cap, just a terrific blonde lid on show.
Give him the World Cup now.
Well, at least we know the bails come off.

I don't know what that was about. The umpires had a discussion, then walked away and nobody was none the wiser. We probably never will be.
What's happened there?!
Joe Root's gone running away in celebration, thinking Nicholas Pooran has smashed his bat into the stumps, but it's actually Jos Buttler's gloves that have disturbed the zing bails.
Double spin now - here's Joe Root.
Now then. Jason Roy has emerged from the dressing room.
He's not on the pitch - he's stood just beyond the advertising boards, talking to a member of the England staff, and going through what looks to be a couple of stretches.
A big swing from Nicholas Pooran, eyeing up Adil Rashid for another six, but the ball bobbles on the bounce to Chris Woakes at deep cover.
Some wristy flicks keeps the singles ticking along but, after a bit of a battering in the last over, that's a good comeback by Rashid.

Jack Kirkland: Maybe an unpopular opinion but I haven’t been that impressed by Rashid this World Cup. Hoping he surprises me this game but he seems to be so readable for the batsmen.

That's better from Ben Stokes, back-to-back yorkers tapped away by the batsmen, before Nicholas Pooran flicks a leggy single away.
A clever bit of running ensures West Indies work two from the final ball of the over.

With this acceleration from the West Indies, Eoin Morgan might be tempted to get Jofra Archer or Mark Wood loose.

Shimron's got his eye in. Down the ground goes Ben Stokes' second delivery, Hetmyer clearing his front leg and thumping the ball back past the bowler.
Shot! A flay of the bat from Shimron Hetmyer, and he clubs Ben Stokes through mid-on for a stonking four.
Cheers, Jack.
I am 100% here to watch Pooran and Hetmyer working the England bowlers around. Two of my favourite batsmen.
A thoroughly intriguing passage of play in store.
And who better to guide you through such intrigue than Amy Lofthouse?
Catch you later.
Only James Anderson and Graeme Swann have more men's ODI wickets at this venue than Adil Rashid (9).

Good reply from Adil Rashid, beating Nicholas Pooran with a googly. Jos Buttler whips off the bails but Pooran never left his crease.
Turn for Rashid there.
