Another over ticks by. Eight from it. England could do with a wicket.
England's best fielder is the square-leg umpire who can't get out the way of a pull shot and saves England four runs.
Stopped with the shin but she's OK to continue.
England are stalling a little, I'm not 100% sure what the plan is. Wolvaardt moves to 32 off 28 with a hack off Nat Sciver-Brunt over the leg-side ring for four more.
South Africa's fifty comes up after 48 balls as Wolvaardt dabs a single into the off side.
I still think England are ahead in this one, but I'm not as confident as I was 30 balls ago.
South Africa are capable of flicking the switch. England need to be wary.
Ecclestone is bowling now, she starts with four singles. I reckon England won't mind that.

I am not sure South Africa are striking quickly enough. England have been scoring so quickly in this tournament you'd think you'd need 170 at least.
Seven comes off Glenn's first over. South Africa are starting to build something.

Wolvaardt is a star of this South Africa side. She played that beautifully.
South Africa are starting to motor along now as Wolvaardt cuts for four more.
England could do with a wicket you feel.
Wolvaardt 18, Brits 15
Better for England as spinner Sarah Glenn starts with a single and a 'skiddy' dot.
Heather Knight has a defensive field now.

That signals there is not a huge amount of pace in this wicket.
And that's the powerplay, South Africa finish it on top as Laura Wolvaardt steps on to her back foot and pulls another one to the fence.
The ball just sort of died there. England can't get much pace on the ball.
Nat Sciver-Brunt is in to bowl the final set of the powerplay.
The ground is filling up now, a really good bubbling atmosphere as NSB fires in a wide delivery.

A little off from Dean in that over. She couldn't get her length right. A little bit of momentum is building for South Africa after a quiet start.
Charlie Dean gets out of a very poor over. 14 from it and just like that South Africa have doubled their score.
It was never going to be easy was it folks?
Launched! Poor ball from Charlie Dean which Laura Wolvaardt picks beautifully and smashes over the covers for a maximum.
Brits pulls a three to take South Africa up to 20. The hosts are rallying.

I am baffled here.

That is a poor call.
