Marizanne Kapp is an imposing presence at the top of her mark.

She powers through another tight over., with just two runs conceded off it. Bangladesh are going nowhere at the moment.

Including her score so far in this match (2*), Sobhana Mostary has scored 98 runs at this World Cup and is 26 away from recording the most runs for Bangladesh at a single edition of the tournament, currently held by Nigar Sultana who scored 123 in 2023.

Sobhana Mostary looks like she has more of a plan that Shathi Rani does.

Mostary looks like she is trying to get across her stumps, I think that's the right plan.

Rani is trying to swing at everything there's no placement - it is hopeless swinging.

Movement off the pitch and through the air for Ayabonga Khaka and Bangladesh pair Shathi Rani and Sobhana Mostary are struggling to get to grips with it at the moment.

There's a couple of lbw appeals after Mostary stepped across her stumps but nothing doing from the umpire.

A disciplined start from South Africa.

Here's how Marizanne Kapp nicked off Bangladesh opener Dilara Akter for a duck a few moments ago.

No bat involved so South Africa burn a review.

It must be tough for Laura Wolvaardt to say no to Marizanne Kapp.

Surprising South Africa have reviewed. Again there was no appeal from Sinalo Jafta behind the stumps.

Bangladesh are struggling to navigate how hard to go. They need to be a bit more proactive and then they'll not have to take as many risks.

Marizanne Kapp is bounding in with real purpose. I mean, does she know any other way?

However, Shathi Rani has a bit of confidence and slog sweeps the South Africa all-rounder over mid-wicket for a couple.

A few balls later and Kapp thinks Shathi has nicked a booming drive and talks Laura Wolvaardt into a review.

Sobhana Mostary’s batting average of 32 at this Women's T20 World Cup is the best of any player for Bangladesh in the tournament's history.

Ayabonga Khaka eases into her rhythm a little more than the fiery Marizanne Kapp which allows Bangladesh to settle a bit more.

Shathi Rani and Sobhana Mostary both off the mark.

Marizanne Kapp is unbelievable, more so because of her longevity.

She has been opening the bowling for so long. To be successful in T20 is not easy, but she's kept evolving.

Marizanne Kapp has a face like thunder.

She thinks there's an edge from Shathi Rani to a ball on a length but Sinalo Jafta gets her footwork slightly off and ends up spilling a diving catch.

That looked fairly routine for the South Africa wicketkeeper, but TV replays show the ball, in fact, clipped Shathi's hip rather than the bat as she attempted to work it to leg.

A little bit of strange one as there wasn't a huge appeal from the wicketkeeper, but Marizanne Kapp was off celebrating!

Dilara Akter has to go for nought!

Right, Dilara Akter has just taken guard at the striker's end.

Marizanne Kapp has the ball in hand for South Africa.

Play!

South Africa have beaten Bangladesh in two Women’s T20 World Cup meetings - winning by by 10 wickets in February 2023 and by 30 runs in November 2018.

Bangladesh are going to need to play better than they did against the West Indies - they only scored 103 and it was nowhere near enough.

They'll learn from that and try put a better score on the board. They restricted England to 118 and if they can get something around the 120 mark they can cause South Africa a few problems.

Bangladesh: Dilara Akter Dola, Shathi Rani, Sobhana Mostary, Murshida Khatun, Nigar Sultana Joty (captain and wicketkeeper), Shorna Akter, Ritu Moni, Fahima Khatun, Rabeya Khan, Nahida Akter, Marufa Akter.

South Africa: Laura Wolvaardt (captain), Tazmin Brits, Marizanne Kapp, Anneke Bosch, Sune Luus, Chloe Tryon, Nadine de Klerk, Annerie Dercksen, Sinalo Jafta (wicketkeeper), Nonkululeko Mlaba, Ayabonga Khaka.

This is the final game in Group B for both of these sides so it's time to talk about permutations and our old friend net run rate (NRR).

With two points and a NRR of minus 0.835 Bangladesh are all but out of the tournament barring a freak result here, and England imploding in their two remaining matches.

On the basis England are likely to beat Scotland on Sunday then it would all boil down to what happens in England v West Indies on Tuesday.

If South Africa win today and England win both their remaining matches, the Proteas will go through on six points as runners-up, two clear of West Indies.

However, if West Indies (NRR 1.708) beat England (NRR 0.653) then those two sides would join South Africa (NRR 1.527) on six points with places determined by NRR. Current NRR for each side in brackets.

So South Africa's aim today is to beat Bangladesh and try to boost their NRR in the process by winning big.

South Africa skipper Laura Wolvaardt: "We are happy to have a bowl. We were a little bit in two minds for this game. Obviously a lot of talk about net run rate and everything. I think you can control that a bit better when you are chasing so happy to have a bowl.

"How will we manage the net run rate? It's a tough one there's so much cricket to still be played in the group. England have only played two so it's hard to know exactly but we just need to win as big as we can. I feel confident we can do that today.

"World Cups just bring the best out in every cricketer and I am happy to be able to contribute. Hopefully we all can to get that win tonight."
