Well they needed that. Brute force, an ugly shot but it doesn't matter. It's effective.
Biffed down the ground for four!
Henry Moeran
BBC Test Match Special commentator
The crowd will try and help as much as they can.
Target 157
"Twooooooooo," bellow the ground as Wolvaardt finds a gap. They get back but it's still a good over for Australia,
South Africa need 53 runs from the last four overs.
A wide helps...
South Africa need another boundary here...
This is good from Ash Gardner. She is firing the ball in and Chloe Tryon can't get it away.

We're going to be talking about one of two things after this game. Has Laura Wolvaardt timed this run chase brilliantly? Or is it too little too late?
A good diving stop prevents Wolvaardt adding another boundary. Everything has to go.

Laura Wolvaardt is keeping South Africa in this final.
Target 157
I tell you if Laura Wolvaardt wins this they'll be naming Newlands and Table Mountain after her.
She smacks another four to end the over, sending the crowd wild.
59 runs are needed from 30 balls.

Laura Wolvaardt is keeping her side in!
You just have to listen to the crowd to know how much it means to everyone out there.
Four more to Laura Wolvaardt!
Springboks captain Siya Kolisi, the South Africa bench and the vast, vast majority of this Newlands crowd are on their feet because that's the 23-year-old's fifty.
Darcie Brown is back to bring some Australian control...

Laura Wolvaardt is now the leading run-scorer in this World Cup.
Need 69 runs from 36 balls
There were 15 runs from that over after the 14 hit in the one before.
There's a chance...

The crowd haven't given up, they certainly believe. South Africa are now going, it's all a bit MS Dhoni for me.
HUUUUUGE from Laura Wolvaardt!
This is better.
Maybe it's just a little bit more likely now...
Chloe Tryon biffs a vital boundary. Siya Kolisa is acting as a cheerleader in the crowd.
