Massive wicket for South Africa and very sporting of Nat Sciver-Brunt to walk off straightaway, too.

I'm pretty sure that Nonkululeko Mlaba did get a little touch on the ball as it went past but the TV replays weren't 100% conclusive so had Sciver-Brunt waited for the third umpire to make the decision, who knows what the outcome might have been?

Probably still out but you never know.

Anyway, Charlie Dean is the new batter for England.

It almost feels like that's the only way you are going to get Nat Sciver-Brunt out today. A devastating way to end a beautiful innings that was going so fluently.

What an unfortunate, painful way to go. Mlaba definitely got a hand on it, although she was just trying to stop it.

The fielding today has been quite disappointing, especially when you know how good a team can be. The timing when you are throwing yourself to the boundary is so important otherwise silly mistakes happen.

No boundaries and just four from Sune Luus' set as South Africa try to regain the control they had in the early part of this session.

Nat Sciver-Brunt has been out there for a while now and asks for some new gloves at the end of the over.

The bad ball every over allows Amy Jones to hit it for four and that gets her going. Then, she will block the straighter ball.

To keep Jones quiet, South Africa need to keep bowling middle and leg.

Two boundaries for Amy Jones as England enjoy their most productive over for some time.

She crunches the first ball of the Nonkululeko Mlaba over through the covers before sweeping firmly behind square a couple of balls later.

A pair of singles later in the over take England to 350.

With wickets falling around her, Nat Sciver-Brunt, after scoring her record-breaking century, has reduced her scoring rate with 20 runs off 39 balls after reaching the landmark.

The ground fielding errors are creeping back in for South Africa and the latest, a completely needless fumble as the ball rolled gently out to long-on, allows Nat Sciver-Brunt to scamper back for two rather than the single it should have been.

England are not exactly flying at the moment, run-rate wise, but you feel like the runs are coming a little easier again and South Africa's energy has dropped.

Nonkululeko Mlaba is back on the money for the first four balls in the over but after a brief delay - for what, it is not entirely clear - she drops short again.

Amy Jones thumps it again, in the air, but out of reach of the fielders in the covers for another boundary.

The ball is doing something but the new ball might turn sharper and skid-on as well. I would take the new ball and bring Marizanne Kapp back into the game but still keep a spinner from one end.

Sune Luus now bowls a long hop to Amy Jones but the England right-hander doesn't get hold of the pull shot and has to settle for one.

It's been all spin since tea but with the second new ball available in six overs, that may change before long.

Poor ball from Nonkululeko Mlaba - a rarity since tea - and Amy Jones is able to go back and pummel it through that packed cover region for four.

It's the only scoring shot of the over but a couple of mistakes are creeping in for South Africa again, they will want to tighten up again before England start to regain the sort of momentum they had in the afternoon session.

A misfield in the covers relieves a bit of the pressure that was growing on England.

It was a wide half-volley from Sune Luus and driven firmly by Nat Sciver-Brunt - but straight to cover.

However, it flicks the fielder's hand and gets through, running away to the short boundary.

There is some turn in the pitch now. Charlie Dean and Sophie Ecclestone will be seeing these balls turn past the outside edge and be thinking that it's good news for them when they bowl.

Two from Nonkululeko Mlaba's latest and it's another over bowled in double quick time.

At this rate, they will have bowled the 98 overs with time to spare.

With spin at both ends and the boundaries having dried up, South Africa are racing through their overs now.

That might be needed to get the scheduled 98 in the day bowled.

England are still being very careful against Nonkululeko Mlaba.

Nat Sciver-Brunt takes a single from the first ball of the over but that's it for the scoring as Amy Jones is dotted up for the next five.

Proactive batting from Amy Jones.

She charges Sune Luus to meet the ball on the full and thump it back down the ground for four.

Seven from the over to get England moving again.
