Stinger!

Having been brought back on strike by a single, Bouchier raps the ankle of Suzie Bates at cover with a fierce drive.

Come on, Bouchier. Give us a game within a game here.

There's no sense of strain in her shots, it's just a free flow.

Fantastic shot!

Bouchier nonchalantly picks up four more, flicking Molly Penfold's delivery off her toes to send the ball down the ground.

She then moves to 92 with a shot down to long-on.

Bouchier crashes Jess Kerr away from four wide of long-off, before taking a single to bring Nat Sciver-Brunt on strike.

The all-rounder does her best to keep Bouchier's hundred hopes alive, facing four dot balls to close the over.

Bouchier moves to 80, driving Amelia Kerr through the covers.

A century is still just about on, but she'll need to retain almost all of the strike - which she does with a single from the final ball of the over.

There was a giggle from Amelia Kerr to Brooke Halliday there because she knows that was a half-tracker.

That is pretty unfortunate for Heather Knight.

It hung in the pitch a little bit and didn't bounce as much as she expected.

Quieter over, just the single from it as Bouchier works Amelia Kerr square.

England are 32 runs from their target - how many balls will it take them?

Oooh, close.

Heather Knight gets a bit overexcited and tries to hare away off for a single into the leg side that isn't on.

Bouchier sends her back and her dive sees her bat bounce up off the ground - had the throw been direct then she'd have been in trouble.

The players are taking drinks.

Heather Knight gets in on the action!

She clouts Brooke Halliday for a flat six over square.

Hundred up for England as Bouchier hits another four, crashing Amelia Kerr to the left of mid-wicket.

She moves to 69 from 61.

Three more fours for Bouchier - she's really motoring along now!

Having brought up her fifty through point she reaches the ropes in a similar area from the following delivery, hitting slightly more loftily.

The England opener makes it three boundaries in a row with a flick through mid-wicket before pulling the final ball of the over away to make it 17 runs from the over, 16 of them hers.

Thanks Tom, all going along quite nicely here despite the loss of Beaumont

Heather Knight gets her first run, edging Sophie Devine away to third, before Maia Bouchier brings up her fifty, driving to the right of point for four. It comes off 54 balls.

With England more than halfway to victory it is time for me to hand over Mike Peter to see us home.

She tried to bowl quicker and it's not easy for a legspinner, and she's dragged it down.

Heather Knight is the new batter to join Maia Bouchier, who has not changed her approach despite that wicket, clubbing a half-tracker from Amelia Kerr through mid-off, before a lofted straight drive lands safe and England run two.

It needs another frame!

This is ridiculously tight. There's lots of rock and rolling going on from the third umpire.
