South Africa dismiss New Zealand for 167 to win by 190 runs
Superb Maharaj claims four wickets, Jansen three, Coetzee two and Rabada one
Proteas post 357-4 after being put in
De Kock hits fourth century of tournament before falling for 114
Van der Dussen makes 133 and Miller adds 53 off just 30 balls
SA now top of table and on brink of semis; NZ drop to fourth
Six runs come from that over, with Mitchell Santner bowling out without adding to his 14 wickets for this World Cup.
Seven overs to go and we're still waiting for the South Africa destructiveness that we have become so used to seeing at this World Cup.
A good century from Rassie van der Dussen today. He's added more than 30 runs to his total since being dropped by Trent Boult on 72.
Santner continues. One of the World Cup's leading wicket-takers is yet to strike today and this is his last chance to do so.
South Africa will have been aiming to get towards around 350, but unless they go full throttle immediately, it feels as if they will fall short of that.

Van der Dussen brings up his century from 101 balls. It's been a very controlled innings.
Now he's got license to go after the bowling.

The innings has been timed to perfection but now you feel he's got to go to fifth or sixth gear.
He's been cruising through the innings but now is the time to accelerate.
Van der Dussen brings up three figures with a calmly placed pull shot that nurses its way to the boundary rope.
100 runs off 101 balls, a steady rate, a good platform and now, you feel he has to try and cash in on what he has got and purely aim to inflict more damage to New Zealand's bowlers.

New Zealand will be pleased that Heinrich Klaasen has yet to appear. He's been a bit of a cheat code for South Africa.

Jimmy Neesham is a bowler that South Africa will probably look to target now.
Halfway through this over from Jimmy Neesham and so far, it has returned three singles.
New Zealand will be ecstatic about this, with South Africa's scoring rate in overs 41-50 at this World Cup streets ahead of any other nation.

David Miller up against Mitchell Santner in ODIs has scored just 14 runs in five innings and been out twice, for an average of only seven.
Just four singles come from that over, which Mitchell Santner and New Zealand will take as a victory.
South Africa have batted well so far, but it has been a bit on the steady side. They need to go big in these final nine overs to ask some serious questions of New Zealand and their ability to chase.

Santner knew it but I can understand why Latham took it on because there were a couple of noises.
David Miller survives, there was clear daylight between bat and ball. A review wasted.

Santner just shook his head.
Daniel Norcross
BBC Test Match Special commentator
Latham likes it but Santner is less keen.
They're going to have a look because he heard a noise.
A potential first-baller for David Miller. A bit of uncertainty as to whether he has edged it. New Zealand take it upstairs.
Thanks, Mike.
De Kock and Van der Dussen have put together a 200-run partnership for a second time in this World Cup, South Africa's fifth double century in history.
They made exactly 200 today and 204 against Sri Lanka.
South Africa do make an interesting call here, with David Miller being introduced at four before Aiden Markram and Heinrich Klaasen.
Right then, an exciting final 10 overs in store. Here's Jonty Colman to take you through them.

That partnership was worth exactly 200. It is the second time Quinton de Kock and Rassie van der Dussen have shared a 200-run stand in this World Cup.
The other was against Sri Lanka.

Soft dismissal from De Kock. He just guides the ball to backward point and Glenn Phillips is never dropping that.
De Kock has a bit of a grimace, he can't believe he has put it there and his good knock comes to an end.
He's been unbelievable and has been playing without fear at this World Cup.
