Sekhukhune has scored 24 runs in this match so far. In her previous 48 matches for South Africa she had only scored a total of 24 so she has doubled her international runs now.
England have got fielders packed in close around Tumi Sekhukhune now.
She deserves a lot of credit for this innings. She only has 15 but she has been so solid and allowed South Africa to just reduce the deficit over by over.

Issy Wong is making things happen.

Here comes first-innings centurion Marizanne Kapp.
Can she dig her team out of another hole today?
She edges her second ball to second slip but it bounces just short and Wong beats her outside edge again next ball!
Kapp responds with a thumping drive down the ground for four. We've got another good contest here and it's only been one over.

That's a great catch by Kate Cross. She watched the ball and followed it and took a great catch to her left to remove the dangerous Lee.
England will feel they've got an opening here and Kapp will be tired after that 150 in the first innings and after putting in a shift with the ball.
Lee c Cross b Ecclestone 36 (SA 118-5)
Big, big wicket.
That has come at a very good time for England as Lizelle Lee was just getting going. She attempts one big shot too many at Sophie Ecclestone and in attempting to hit over mid-off, skies the ball high, high in the air and Kate Cross takes an extremely well-judged catch running backwards.

We've got the brains trust all having a gander. Ecclestone, Knight and Sciver are together to see how they can get Lizelle Lee who has played some great shots so far.
It got a bit chaotic a couple of overs ago with a few missed chances. The first drop of Amy Jones' was the only real, legitimate chance, and Lizelle Lee has frustrated them since.

England are building up this pressure nicely and it's caused the two batters to come together in the middle for a bit of a chat. Lee just passing on some wisdom.
Issy Wong is making things happen.
She gets a ball to take Sekhukhune's outside edge that just drops short of gully before pinning her on the pads with a full toss.
It's given not out but Wong hangs around in the middle of the pitch as if hinting for a review but Heather Knight has already turned her back, walking back to her position at slip.
Replays show it was going miles down the leg side, but that's a maiden.

It's not often you see players going after Ecclestone but Lizelle Lee is seeing it well and taking her on.
Trail by 15
Lizelle Lee is not going to let Sophie Ecclestone settle here and, as Australia taught us over the winter, that's the best way to play her.
She gets down on one knee and slog sweeps for four. Tidy.

England all-rounder on BBC Test Match Special
Issy Wong getting a bit caught up in everything that is going on. She needs to just calm down a little bit there.
Ohhh dear.
Issy Wong gets a bit too frustrated as she throws the ball back at Tumi Sekhukhune in her follow through but it's a wild one and Amy Jones is a) nowhere near it and b) not expecting it so the ball runs away for four.
Wong apologises and walks away for a calming down stint on the boundary.
Georgia Elwiss
England all-rounder on BBC Test Match Special
I wonder if Issy Wong will have had a quick word with Lee on the way past just to let her know she's still after her and she's still coming.

Lizelle Lee has given that the beans!
Lizelle Lee gets straight back into action after a drink as Issy Wong offers some width and she pummels it T20-style over mid-off for four!
Georgia Elwiss
England all-rounder on BBC Test Match Special
The momentum shift since Lee has come out has been interesting. She's always going to play in that aggressive way and has made up her mind how she's going to play. She's got a solid partner at the other end and they're doing a great job of rotating the strike.
England started the session brilliantly, removing Sune Luus, but they've been frustrated by the stubbornness of Sekhukhune and the aggression of Lee.
They were very close to getting Lee out lbw early on but their review was unsuccessful and she's made it count.

The first 11 overs of the day saw just 10 runs but the next 9 overs we've seen 38 runs.
