A long Jordan over gets even longer when he sends down a wide - but the force is with De Kock when even a good yorker is drilled back past the bowler, off the toe end of the bat, for four. He has 105 from 98 balls. SA need 145 from 20 overs - or 120 balls, should you prefer.

Jordan bowls a high full toss to De Kock - so high, in fact, that it's called a no-ball. De Kock has fended it off for a single, but it means Amla will have a "free hit". But as Amla backs away, Jordan fires it in, yorker-length, outside off stump and the danger is averted.

"A standing ovation for De Kock, not just from his team-mates but the whole ground."

De Kock steers Stokes for two to move to 99, then has to dig out another good yorker - but as he guides a short ball for a single to fine leg, the whole ground rises for his second century in three games. It's his 10th ODI century, from 96 balls. Well batted, sir.

"He was done, he would have been a goner. If only Jordan could produce more of those ones at key moments."

De Kock has to jam his bat down on a good yorker from Jordan, miss that and he'd have been plumb lbw. I know that yorkers are no longer "en vogue" in modern international cricket, but I'd humbly suggest that's probably the best ball I've seen Jordan bowl this series, and perhaps he ought to try to repeat it. But no, the last ball is banged in halfway down, De Kock launches another one into the sky over mid-wicket, is that four or six? Looked to have hit the boundary "rope" on the full? It's four.

A single means this is now the highest opening partnership for SA against England in ODIs, beating the 156 by Andrew Hudson and Gary Kirsten in 1995-96.

Rashid wheels away for his seventh over, it's not been the Yorkshire leggie's day with the ball. It's a fairly tight over, just two from it, and Rashid has 0-35 from seven.

And for those of you hoping for a weather intervention... if it rained now, SA are more than 20 above the D/L par score.

"It is incredible, Amla has got great hands. When he is at his best, it is his wrists that are the thing."

De Kock sees off the over. What can England do now? Bowl for run-outs?

"I would never be an umpire, it is hard work all this."

Replays show the ball clipping the edge of De Kock's right pad as he played and missed down the leg side. Not a great call from Jos Buttler who immediately signalled to his captain that he wanted the review.

Chris Jordan returns, banging in an attempted bouncer, but Amla is calmness personified as he plays the ball late, guiding it through third man for four. Jordan then bowls one down the leg side, umpire Cloete signals a wide, but England - with more than a hint of desperation - call for a review for a catch behind...

"They cannot contain him. De Kock, in no time at all, is into the 90s."

De Kock continues to show England a clean pair of metaphorical heels as he clubs a four past the square leg umpire. The Proteas are very much on top at the halfway stage. The irrepressible De Kock has 91 from 80 balls.

"You have got to keep control as long as you can The batsmen are in comfort mode. You have to try and make it uncomfortable."

De Kock eases the pressure with another six off the second ball of Rashid's sixth over. A loose full toss gets what it deserves and is smacked over long-off.

"They are making it look very comfortable. Every now and again when you think they are just playing ones and twos, Quinton de Kock just explodes."
