Highlights on BBC Two and iPlayer from 23:15 BST
Amy Jones and Bess Heath, neither of whom are afraid of giving it a biff, are England's batters charged with boosting England's total in the next four overs.
Here's how Maia Bouchier fell agonisingly short of a first ODI century.
Daniel Norcross
Commentator on BBC Test Match Special
It's not the easiest catch - none of them are in these conditions.
But Nat Sciver-Brunt walks off to a standing ovation.
Sciver-Brunt c Madavi b Ranaweera 120 (Eng 233-4)
Sri Lanka hold on this time.
Nat Sciver-Brunt's innings of classical brilliance and brutality is over as she chips Inoka Ranaweera into the hands of Harshitha Madavi at deep long-off.
Brilliant from the stand-in England skipper.
Sciver-Brunt removed at 120
Nar Sciver-Brunts offers a chance down the ground as she wallops Inoka Ranaweera down the ground, but the ball falls short of the diving fielder at long-off.
Next ball, Sciver-Brunt is down on knee and crunches Ranaweera through the covers for another four.
That is Nat Sciver-Brunt's eighth ODI hundred and her third in her last four innings.
Georgia Elwiss
England all-rounder on BBC Test Match Special
It has been a masterclass from Nat Sciver-Brunt.
There was a point where every ball felt like it was going for four. It hasn't been slogging either, both batters just played proper cricket shots.
Nat Sciver-Brunt does not let the wicket of Maia Bouchier affect her mentality at all, as he pumps Kavisha Dilhari for three consecutive fours - biffed through fine leg, scooped over the wicketkeeper's head then deftly pushed through extra cover.
She's on fire.
Georgia Elwiss
England all-rounder on BBC Test Match Special
She has been magnificent. She got starts in the T20s and didn't quite show what she was capable of, but she showed all her quality today.
Cricket can be cruel sometimes.
Aatif Nawaz
BBC Test Match Special commentator
That is so disappointing, but a terrific innings.
Bouchier lbw b Dilhari 95 (Eng 211-3)
No she cannot as Maia Bouchier misses out on a maiden ODI century after being trapped lbw by Kavisha Dilhari.
It's full from the Sri Lanka off spinner and Bouchier attempts to haul it to leg but misses out and, after a very brief conflab with Nat Sciver-Brunt at the non-striker's end, is on her way.
Maia Bouchier is on 95 off 64 balls. Could she break the record Nat Sciver-Brunt has just set?
Russel Arnold
Former Sri Lanka all-rounder on BBC Test Match Special
It has been fantastic. She has scored all around the ground and I think she only missed two deliveries in the entire knock.
Aatif Nawaz
BBC Test Match Special commentator
It has been an outstanding innings.
Nat Sciver-Brunt is back in the side and back doing what she does best.
Nat Sciver-Brunt brings up century in her 100th ODI appearance with a neat flick off her legs from the penultimate ball of Achini Kulasuriya's sixth over.
She's broken the record for England's fastest ODI hundred off 66 balls.
A fine innings.
Aatif Nawaz
BBC Test Match Special commentator
It's neck and neck in the race for the fastest hundred!
Nat Sciver-Brunt is 98 off 64 balls while Maia Bouchier has 88 off 60.
Both could break that record here.
England's fastest ODI century is 70 balls by Charlotte Edwards.
It was scored in 2012, against New Zealand.
She's on her way to a century but here's the best of Maia Bouchier's half-century.
Aatif Nawaz
BBC Test Match Special commentator
It has been a remarkable display of batting.
Nat Sciver-Brunt eyeing up a hundred gets a little giddy and a filfthy swipe to Udeshika Prabodhani just misses her off stump.
