It was all down to a heroic last over from Mark Wood.
South Africa lost the first ODI of the series by 72 runs.
"At Leeds we got ourselves in a position where we could have possibly won the game with the bat... and with our strong middle order we should have done better". Alex Hales and Joe Root responded well, the pair putting on 58 prior to de Kock catching Hales behind the stumps attempting a tight cut.
England had been sweating over Stokes following the first ODI at Headingley, where he injured his knee while bowling. Two singles were followed by a dot ball, a single and another dot ball. Stokes subsequently hoisted both medium-pacer Andile Phehlukwayo and Morris high over deep midwicket for sixes. We all saw how easy he made batting look in the opening ODI.
Jos Buttler eased himself into the innings, while Stokes took charge.

Miller was unbeaten on 71 and Morris on 36 as South Africa failed to take a winning chance for a second straight ODI. Amla was hit flush on the helmet grille by Wood before falling falling for 24 when he drove Stokes to Morgan at short extra cover.
Quinton de Kock gave the South Africans an excellent start to their chase with a rapid 98 while AB de Villiers hit 52 to keep up the momentum, and it was touch-and-go right to the end as to whether they would get over the line.
But Morgan searching for a breakthrough turned to Plunkett, and the Yorkshire paceman instantly found reward, dismissing de Villiers soon after reaching his half-century.
Next ball produced another edge, with de Kock failing to hold a more hard chance.
Amla- On a flat pitch, it would be a folly to play without South Africa's run-machine.
