A great bowling change from Meg Lanning - the captain introduces her own potent brand of partnership-breaking, slingy right-arm seam - and it traps Brunt in front second ball.

England won toss
Brunt bludgeons a two down to fine leg, where Grace Harris makes a good diving stop, but with 36 needed from 48 deliveries, there now seems to be an increasing belief around Cardiff that England might pull this off. (Famous last words).
Australia could do with a wicket, so turn back to Rene Farrell - and Sciver nurdles a single to fine leg to bring up the fifty partnership.
A boundary at the start of the over always takes the pressure off - and it's a profitable over for England as their fourth-wicket pair plunder four more singles. This stand is worth 49, and England need 41 from 54 balls.

Quote MessageIt has been a low-scoring affair but we have seen the most amount of sixes yet in this series. Grace Harris hit three and now Sciver has got in on the action. This is an interesting phase of the game now.
Now it's Katherine Brunt's turn to join in as spinner Grace Harris - bowling with her cap on - is despatched for four through mid-wicket on her first delivery.

Quote MessageSciver is a strongly-built, athletic player. The first six for England is a sign of what she can do.
Our first sight of Australian spin today as they turn to slow left-armer Jess Jonassen, who's had a marvellous series with bat and ball. But the increasingly assured Sciver hoists her for a six over long-on. At the halfway stage, they need 49 from 60 balls.

Quote MessageIn the T20 format Sciver has come on and got wickets but her main role is to bat. She hasn't fulfilled that much yet this series. But she has a chance here to see England through to a win.
There's some nail-biting in the England dug-out (both literal and metaphorical) but there's a decent round of applause as Sciver and Brunt push the score past 50. Sciver seems to have adjusted well to this pitch, cutting Coyte for a two and a three. Her 24 has only taken 22 balls - and she's kept the strike.
Healy belatedly stands back from the stumps, but that gives Sciver the chance to come out of her crease next ball. Healy then comes back up to the stumps - this is more like a game of Grandmother's Footsteps than cricket this over - but Sciver keeps the score ticking with ones and twos. 66 needed from 72 balls.
England's men have started to arrive at Cardiff for their T20 international which starts at 15:00 BST - we'll have full coverage of that one later on - but for now it's feeling like an uphill struggle for their female counterparts - although if Healy keeps missing legside wides, letting another one through to the boundary for five wides, it could be a close-run thing.
More fluent batting from Sciver, guiding Coyte for two through extra cover. She has 14 from 13 balls.
All right-arm seam so far from Australia as the Southern Stars turn to Sarah Coyte's medium pace - but she fires one down the leg side which beats Brunt, wicketkeeper Healy and disappears for five wides. They all count, England...

Quote MessageAll England need is the grit to see them over the line. Australia have shown that hunger and desire over the series. England can bring this home comfortably but they need the belief to do so.
Brunt is off the mark with a two and a single as the powerplay concludes.
Eng 26-3
Despite Farrell's excellent figures, Australia make a change and turn to fellow right-arm seamer Megan Schutt. Brunt hasn't connected cleanly yet, and when she is sent back by Sciver, Schutt has the chance to run her out but her underarm throw misses the stumps at the striker's end as Brunt pulls out the full-length dive.
