Amy Satterthwaite - who hit an important 54 with the bat - comes on with her off-spin.

Knight and Jones look comfortable out there as they work the gaps for five singles from the over.

Some of the England team are wearing lots of layers, as are some of the fans. It's getting nippy in Derby.

Thanks, Ffion!

Will England chase down 245? Will New Zealand win and take us to a series decider on Sunday?

We have 25 overs to go and it could go either way - don't go anywhere.

Amy Jones drives beautifully down the ground to add four more runs to England's total.

It's another passage of the game now where batting is looking pretty comfortable. The trend of the series has been a pair gets themselves settled, and from nowhere a wicket falls.

Can these two defy the trend and see England home? Kal Sajad is here to take you through to the end.

These two are just starting to settle a little for England. They're finding it easy against the spin of Kasperek.

Eight runs from Leigh Kasperek's over, who isn't giving New Zealand the level of control that they would have been hoping for from her.

There's no spin and she hasn't had the consistency of Charlie Dean, who took three wickets earlier.

Nat Sciver hasn't had a good series with the bat, potentially one of England's players who is feeling tired after a very intense summer.

Jess Kerr returns and goes for just two, including a big swing and a miss from Amy Jones off the final ball that she's lucky not to edge behind.

That's a lovely looking shot. It was a real full-fledged swipe of the bat.

Well that'll ease the pressure.

Heather Knight reverse sweeps Leigh Kasperek's first ball for four before Amy Jones goes for a more conventional drive, but with the same result.

Looks like they're going to target the spinner after the seamers bogged them down.

England 77-3 after 20 overs and New Zealand were 82-3.

England are looking to rebuild. The run-rate is similar to where New Zealand's was at this stage and they've lost the same amount of wickets. It's a crucial phase in the game for England's batters given what we've seen in the series.

England are in the rebuilding phase but New Zealand are keeping them in check. The pressure's building and it feels like something has to give.

Who's going to crack first?

Jensen and Rowe have bowled well here. They've bowled tidily and in partnership. England need to be careful.

Amy Jones nearly falls to the trap - New Zealand have a catching midwicket to her from ball one because so often she's been out chipping the ball there. Luckily for her, this one just drops wide and she scampers a quick single.

Another testing over from the impressive Hannah Rowe. They've really put the squeeze on England and stopped those runs flowing.

Wonder if Henry or Alex can provide us with a melting update? I suspect that might be something to do with the sun, though.

A maiden from Hayley Jensen.

Amy Jones and Heather Knight look very relaxed as they meet in the middle for their between-overs conference.

Another good over from Hannah Rowe, who has been superb and caused real problems for all the batters so far.

It's been said about a fair few of England's dismissals in this series but Tammy Beaumont won't want to see many repeats of this one.
