LIVE: England lose early wickets against South Africa in Super ...
De Kock picked up where he left off against the USA, taking on all the bowlers and coming out on top.
By the end of the tenth over, South Africa were 87/1, having lost only Reeza Hendricks, caught by Harry Brook off Moeen Ali.
However, there was certainly a shout for a De Kock dismissal as Mark Wood thought he had caught him at the start of the ninth - but TV umpire Joel Wilson judged that his fingers had been pointing downwards and not taken the catch cleanly.
Still, there was some stellar fielding to come, primarily from captain Buttler behind the stumps.
First he removed De Kock with a magnificent leaping one-handed catch off the bowling of Jofra Archer.
And then he ran out Heinrich Klaasen with an exceptional piece of work, picking up the ball and turning quickly to throw a direct hit at the stumps.
His opposite number Aiden Markram had a less successful time of it, dragging Adil Rashid on to the stumps for just a single run.
And at the start of the last over, Archer took two in two balls, with Brook's catch to dismiss David Miller for a creditable 43 before Marco Jansen chipped to Sam Curran at cover for a duck.
