Aiden Markram is a very classical player. This is what the South African middle order can do with a platform.
Heinrich Klaasen follows that with a beautifully timed drive straight down the ground for four.
These two can be destructive but they are also two of the most delightful players to watch if and when they get going.
SA 192-3
Cheers, Jonty.
And my word, Aiden Markram. At least give me a couple of dot balls to get settled in.
He absolutely drills Mark Wood's first ball straight at Dawid Malan at close cover. It feels harsh to call it a drop, because it's more a case of Malan saving his teeth than an attempt at a catch.
Either way, it doesn't stick, but blimey. That was hit very, very, very hard.
The way he has bowled, you would not think Adil Rashid is struggling physically at the moment.
With 20 overs to go, South Africa are approaching 200 and you feel this partnership is crucial to their chances of a very big score.
To take you through the final 20 overs of this innings, I shall hand you over to Ffion Wynne.
Cricinfo's Matt Roller: Adil Rashid is clearly struggling physically - doubled over between overs while fielding on the boundary after a stomach upset - but is keeping England in this match. Two massive scalps in the middle overs already.
Adil Rashid is really getting some joy here, there was almost a caught and bowled chance for him, with Markram and Klassen both struggling to get their shots away so far.
Meanwhile, over at the Bharat Ratna Shri Atal Bihari Vajpayee Ekana Cricket Stadium in Lucknow the Netherlands are making a decent fist of it against Sri Lanka.
Sybrand Engelbrecht (70) and Logan van Beek (59) helped the Netherlands recover from 91-6 to post 262 all out after they won the toss and decided to bat first.
Off-spinner Aryan Dutt has since bagged two wickets - the dangerous Kusal Mendis one of them - to reduce the Sri Lankans to 104-3 off 16.3 overs.
Since the World Cup four years ago, Heinrich Klaasen has the best strike rate against spin in ODI cricket.
He will look to target Adil Rashid, who will continue his spell at the other end.

That is a fine shot. It was not a half-volley, he had to greet the ball on the bounce and still had the power to beat Ben Stokes at mid-off.
That is up there with the one of the shots of the day.
Back-to-back fours from Markram off Atkinson, two great shots from South Africa's stand-in captain.
A push from Markram gives him the first boundary through the off side, but it was hardly a bad ball from the Surrey quick.
The second is whacked over mid-wicket and runs through to the sponge.

A beautiful shot from Heinrich Klaasen, hitting with the spin.
England are toiling out there.
There have been a lot of rotations of fielders since the beginning.
Rashid gets punished in the last ball of the over, with a gorgeous reverse sweep from Klassen guiding that shorter ball for four.
We have seen Reece Topley doing some work on the boundary, first with a ball and now a medicine ball. Perhaps, he will return to the field soon.
A good over for Atkinson on World Cup debut. He gives away just five runs, four coming from that excellently timed cover drive from Klaasen.
Adil Rashid will stay on at the other end.

I have no idea what Joe Root heard there. It's a significant gap between bat and ball.
Not a great review, clear daylight between bat and ball.

Joe Root is appealing from mid-wicket. He is convinced but I'm not sure how he heard anything from the noise out there.
There was nothing from the bowler.
England end the over with a review.
Atkinson's bouncer looked to be hooked away by Markram, but he misses.
Buttler thinks there might be a top edge. Atkinson does not seem too moved, but Root is very keen and they take it upstairs.

There is a lot to like about Gus Atkinson. He hasn't played much List A cricket and that is a debate in itself but he has got a lot of potential and he has got a lovely simple bowling action.
A brilliant first two balls for the neutral in this battle between Atkinson and Klaasen.
The first beats the bat and really is an excellent delivery.
The second? Crunched for four by the No.11 ranked ODI batter in the world.
