New Zealand are forced to deal in singles in Marco Jansen's latest, getting three of them in total.
Rachin Ravindra swishes at the last, trying to uppercut it but gets nothing but fresh air.
Target 358
A three! That's something of a rarity at this World Cup - and in one-day cricket in general.
It comes as Will Young flicks the ball over mid-wicket but it slows up as it approaches the boundary sponge and Reeza Hendricks is able to flick it back.
Steady start from New Zealand.

That's bounced over middle and off and gone way to the right of Quinton de Kock. That swung!
Target 358
Marcos Jansen is causing some real problems for New Zealand.
The left-armer beats Rachin Ravindra on the inside edge with a ball that nips back and then keeps going to get past Quinton de Kock for four byes.
Will Young then tries to take on a short ball, mistimes it but just gets enough on it to loop the ball over the mid-wicket fielder for a single.

Rachin Ravindra's father named his son after Rahul Dravid and Sachin Tendulkar, his two favourite cricketers. Growing up my favourite players were Geoff Boycott and John Edrich, so what would that be... Boydrich?

Rachin Ravindra has scored 406 runs at an average of 81 in this tournament.
There is quite the reception for Rachin Ravindra as he walks out, the New Zealand left-hander has announced himself at this World Cup and found plenty of new admirers.
He has to wait to take strike, though, and before he does, Will Young drives Lungi Ngidi for four - it should have been stopped by Keshav Maharaj lets the ball through his legs.
When Ravindra does get on strike, he gets off the mark first ball with a single.

Marco Jansen has taken most of his wickets in the powerplay, they're using his power up front.
Conway c Markram b Jansen 2 (NZ 8-1)
That run continues for Devon Conway.
He played and missed at the first ball of the Marco Jansen over but no such luck with the last.
It's a back of a length delivery, Conway pushes at it and a thick edge is superbly snaffled by Aiden Markram, diving to his left at second slip.
Phil Long
BBC Test Match Special statistician
Devon Conway scored 152* against England off 121 balls - in the five matches since he's failed to go past 50.
Target 358
Lungi Ngidi takes the new ball from the other end and that is a very tidy start from the South Africa fast bowler.
A maiden as Will Young is unable to get the ball through a packed off-side field.
Target 358
Six from the over, a decent start to the chase for New Zealand.
Albeit the required rate is now 7.18 an over. As South Africa have shown throughout this tournament, though, with a solid platform, you can catch up quickly late in the innings.
Target 358
A bit of shape early for Marco Jansen but that just takes the ball onto the pads of Will Young, who flicks it away fine.
Four.
Everybody ready?
The New Zealand openers are out and Marco Jansen will bowl the first over for South Africa.
Two slips in place.
Thanks, Jonty.
The expectation is that this pitch will be better for batting under lights. That was one of the reasons Tom Latham gave for New Zealand batting first.
However, good pitch or not, 358 is a big chase and would challenge any side. South Africa's bowlers are pretty handy, too...
That's all from me for now, I shall hand you over to Sam Drury to take you through the start of this New Zealand chase.
A cameo performance from David Miller made a big difference, bringing up a half-century off 29 balls.
That spell included hitting these back-to-back sixes...
Trent Boult was the pick of the bowlers for New Zealand. He only took one wicket, but it was that of captain Temba Bavuma, having conceded only 49 runs off his 10 overs.
South Africa's score of 357-4 was largely down to the performances of both Rassie van der Dussen and Quinton de Kock.
Both men scored centuries and together, they made a partnership of 200.
Watch all of their best shots from that first innings here.
After a blockbuster World Cup with four centuries so far, will South Africa's Quinton de Kock re-think his ODI retirement plans?
