Game will respect game. Kapp will respect Ecclestone and wait for that bad ball and then try and put it away. She's not going to take unnecessary risks.

Sophie Ecclestone purses her lips between deliveries to Marizanne Kapp. This is an intriguing battle.

Charlie Dean fumbles in the ring to allow Kapp to pick up a single, much to the England left-arm spinner's chagrin.

Spin from both ends as Charlie Dean is brought into the attack, but the runs are flowing a little easier for South Africa now.

A little too much turn from Dean's fourth delivery and Sune Luus with a tidy leg glance for four.

You can already see Marizanne Kapp trying to be proactive against Sophie Ecclestone, getting back into her crease and manoeuvring the ball into different gaps. And because England have got this aggressive field, they've got three close fielders in, there are gaps for South Africa to score.

You can't just be a sitting duck for Sophie Ecclestone as Wolvaardt found out. She will just keep firing it in. It's good to see Kapp trying something different to make England think.

Sophie Ecclestone is smirking again, but there's more than a touch of frustration.

A rather filthy hack from Sune Luus flies over the slip cordon and races away for four through third.

Two balls later and Ecclestone is not quite so sanguine when Marizanne Kapp whips it off her legs for another boundary all along the carpet.

England have kept it nice and tight, they haven't run away with things. They got the crucial wicket just before lunch, which should've been taken an hour and a half earlier. Filer should have been kept on. England made up for an error there.

In the afternoon session yesterday, England really got into it and got a lot of runs scored. It's not going that way for South Africa.

I think Laura Wolvaardt's bat was close to the pad. It was very close. Umpires are human beings and that's what DRS is for. That's exactly why it's so frustrating.

Marizanne Kapp confidently plants her front foot and drives the first ball of Lauren Bell's ninth over for four.

A couple of balls later and Kapp rides the bounce and guides a short-ish delivery through point for four more.

There's not even a flicker of joy on Kapp's face for either shot. The cameras cut to Laura Wolvaardt watching on from the stands, rather glum. Clearly the South Africa captain is still rather annoyed by her dismissal.

Typically miserly from Ecclestone going for just 13 runs in her first 10 overs. Only once in Test cricket has her economy been lower after 10 overs - against South Africa in Taunton (2022) where she conceded just 12.

Sophie Ecclestone wheels away, round the wicket, with that familiar action of hers.

Marizanne Kapp works her first delivery it into the leg side before Sune Luus blocks out the next five.

A much-needed boundary for South Africa, their first for a while.

It takes the pressure off Sune Luus, who's been in for a while and needs to take that responsibility as Marizanne Kapp gets settled in.

Lauren Bell takes a breath, pontificating bowling strategies at the top of her run up, before skipping into her stride and bounding into the crease.

Plenty to think about between overs as she strays on to the legs of Sune Luus and she elegantly flicks off her heel for four through the leg side.

This is a huge moment with Marizanne Kapp early in her innings. She's the glue for South Africa, her and Laura Wolvaardt.

England will be hoping to get rid of her early because a bit like Nat Sciver-Brunt, you have to get her early or it's difficult to get her at all.

England captain Heather Knight is grinning after a quip is delivered by a colleague.

Marizanne Kapp does not carry the air of someone willing to indulge in such light-hearted patter, though. She's made a diligent start to her innings against Sophie Ecclestone.

England will hope the departure of Laura Wolvaardt opens up an end.

A leading edge from Sune Luus off the final delivery of Lauren Bell's over sees the ball spoon up into the air towards the point region, but it plops safely into the turf.

England building some pressure here.

South Africa needed to be proactive against Sophie Ecclestone because if she just twirls away from one end, the pressure will tell eventually and it did with Laura Wolvaardt.

She looked frustrated with herself because she'd done all the hard work, she'd got through the tough passages, and let it go.

I can understand why it's been given. The question is would it have gone on with the angle of the arm? But because Wolvaardt was trapped on the crease, the umpire probably felt it was going to hit the stumps. It was a tighter one than some of the other decisions we've seen.

You could see the frustration from Wolvaardt there because she was eyeing up three figures. For England, that is the big wicket that they wanted.

Ryana MacDonald-Gay is patiently chugging in, attempting to winkle out a wicket with control and persistence rather than anything more extravagant.

South Africa's batters happy to nudge her into the gaps at the Mangaung Oval in Bloemfontein. Three runs off the over.

A bit of flight offered by Sophie Ecclestone as she tempts and teases Laura Wolvaardt. However, the South Africa will be not be moved and defends stoutly.

Ecclestone finishes the over chuckling to herself. Wolvaardt has a decidedly more steely look on her face.
