Alice Capsey at her home ground, in front of the Australian dug-out, with her safe hands!
Jonassen c Capsey b Ecclestone 6 (Aus 168-8)
Is this the game?
Jess Jonassen looks to go big down the ground but can only pick out Alice Capsey on the long-on boundary.
Australia need 19 off four balls.
Need 19 from 5 balls
A single to start.

This game's not over, Perry on strike. This is an absolute thriller. England were walking it at one stage, Australia need 20 from this over, the world's best bowler to bowl it, but that doesn't mean she doesn't make mistakes or feel pressure.
Sophie Ecclestone is doing her best Stuart Broad impression.
She's geeing up The Oval crowd.
Ellyse Perry is on strike.
Sliced in the air by Jess Jonassen but the ball lands safe.
Australia need 20 from six balls.
Need 22 from 7 balls
Four!
Superb placement from Jess Jonassen as she bisects two leg-side fielders to find the boundary.
A wide from Lauren Bell.
Make it 26 from eight balls required.
Jess Jonassen, who has opened in T20 cricket for Australia, is the new batter.
They just keep on coming.

It beats Georgia Wareham who's trying to lift the ball over the leg side. Lauren Bell punches the air, it's a huge sigh of relief as Wareham was going so well.
Wareham b Bell 19 (Aus 160-7)
Bowled her!
An almighty heave from Georgia Wareham and she misses.
Lauren Bell doesn't with the back-of-the-hand slower ball smashing into off stump.
Australia need 27 from eight balls.
Need 27 off 9 balls
A tumbling Sophie Ecclestone restricts Australia to a single.

Former England bowler on BBC Test Match Special
Lauren Bell will look to take the pace off, back of the hand slower balls for all of this over.
Need 28 off 10 balls
Ellyse Perry chips for two into the leg side.
Alex Blackwell
Former Australia batter on BBC Test Match Special
It's still game on. There's big pressure on this penultimate over. We saw at Edgbaston, we thought maybe Ecclestone to bowl that second last over to put the pressure on, but Knight is backing the less experienced Lauren Bell.
Need 30 from 11 balls
A single to start.
Same again from England.
Lauren Bell is going to bowl the penultimate over.
That will leave Sophie Ecclestone for the last.
Need 31 from 12 balls
Superb from Sophia Dunkley!
Ellyse Perry crunches a sweep away but Dunkley gets round, and a strong left hand keeps it down to two.
Two overs left. Where do England go? They kept Sophie Ecclestone to the last at Edgbaston.

The game is swinging violently in the way of Australia!
