Green st Healy b Wareham 28 (NZ 108-4)
Georgia Wareham again! Just as New Zealand's hopes had increased once more the young leggie finds a bit of magic. It's a replica of the Devine wicket with a big leg-spinner tossed up and a stumping competed as Green came out of her ground.
A big blow for New Zealand.

These two teams always take things down to the wire. The challenge Meg Lanning has got is that she's got to find two overs which Ellyse Perry would normally have bowled.
The excellent Georgia Wareham is into her final over. Maddy Green looks in the groove a flick of the wrists brings her four more. Is it happening?
Target 156
New Zealand need 53 runs from 30 balls to reach the semi-finals and knock out Australia.
Australia are going to have to finish without their best player...
Is this still on? Could New Zealand do it?
Katey Martin finds the boundary now.

You don't see Schutt drop too many of those. You could see how angry she was with herself with the way she fired it back into the keeper.
Megan Schutt drops a sitter! Maddy Green hit it straight to her at extra cover. Could that cost Australia?

To add insult to injury, that six landed in the Australian dugout and had to be thrown back by the coaching staff.
Green goes big! That's six. She isn't done yet.
How has that missed?! Green inside edges one within a whisker of her stumps and gets four.
Target 156
Australia wicketkeeper Alyssa Healy is barking at her fielders, asking for more and more. Australia are well on top.
When Devine was in New Zealand had a decent chance but it's a really tough ask now. Maddy Green hit this six earlier and she's going to have to take on the scoring now.

Australia coach Matthew Mott will be giving himself a pat on the back - it's been a good decision to bring Georgia Wareham into this side.

That is the defining moment in this knockout match, you feel. New Zealand's key batter has been enticed, beaten and stumped.
Devine st Healy b Wareham 31 (NZ 81-3)
Sophie Devine is out! Is that the game?
It's brilliant bowling from young leg-spinner Georgia Wareham as she tempts the New Zealand skipper out of her crease. Alyssa Healy completes the stumping and Australia are racing around in celebration.
Huge moment.

I had dinner with Meg Lanning last night and she didn't seem nervous at all.
A reminder that whoever wins this game will make the semi-finals and whoever loses is out. Jonasson is doing a fantastic job for Australia. New Zealand can't get her away.
The White Ferns need 75 runs to win from 42 balls.

It feels like there's tension in the ground - nobody knows who is on top and what is going to happen.
Jess Jonasson is back into the attack as Meg Lanning tries to regain control. New Zealand can't afford to let her bowl as economically as her first spell.
Need 81 runs to win from 48 balls
With the six hit on the first ball, New Zealand are happy to take singles from the remaining five balls.
The required rate is now 10.12 but the White Ferns are hanging in.
