SA 160-2published at 27 overs
Right, time for some pace. Can Mark Wood make an impact in his second spell?
He's on the money with the first three balls, conceding just one, before a superb bit of fielding by Eoin Morgan to make a vital stop on the fourth.
The fifth finds the inside edge of De Villiers' bat and runs away fine for four. Streaky stuff, but it's still five runs off the over.

Graeme Swann
Ex-England spinner on BBC Test Match SpecialWhen I played, De Villiers was more effective in the white-ball game. He's a lucky batsman, he had a habit of getting away with decisions that others wouldn't.
SA 154-2published at 26 overs
Risk-free cricket from South Africa as this accomplished pair just keep things ticking over nicely.
A nudge for a single here, a push for two there and nothing rash, just hitting the odd bad ball for four with excellent timing.
Simple stuff once again as they nurdle Rashid around for eight off the over.
South Africa wickets to fall so farpublished at 17:00 British Summer Time 27 May 2017
If you're just joining us, it's largely the De Kock and De Villiers show at the moment.
But it's not been all bad for England - the hosts have picked up a couple of wickets, with Stokes removing Amla and Plunkett finding Du Plessis' edge.
How they'd love a couple more.
SA 147-2published at 25 overs
Quinton de Kock, now batting in a cap, continues his run of sublimely-timed flicks and clips through mid-wicket as he brings up his 10th boundary of the innings.
His partner, still batting in a helmet, gets in on the act as he steps away and smashes Moeen over wide mid-off for four.
That De Villiers boundary brings up the 50 partnership. These two have put on 53 off 53 balls. England desperately need a couple of quick wickets.
SA 136-2published at 24 overs
Shot! AB de Villiers gets himself set and lofts Adil Rashid away over cover for four.
Bit more flight on that one from the leggie but the South Africa captain was ready for it.
Got response by Rashid though as he concedes only one more run off the over.

Ex-England spinner on BBC Test Match SpecialAt the minute, the bowling team have their nose in front, only because of scoreboard pressure. However, with these two at the crease, I'd happily be South Africa.

De Kock 70, De Villiers 16
Moeen Ali rifles through another over. He's solid again, conceding only five runs.
England's spin twins have been accurate but De Kock and De Villiers look largely unruffled at the moment.
SA 126-2published at 22 overs
Image source, Rex FeaturesAdil Rashid almost bowls De Kock around his legs with a googly but as it's down leg, it's called a wide.
A sickening quirk of the cricket laws there, ruthlessly enforced by the umpires.

Ben Wire: South African batting seems under-confident. South African sport in general seems subdued right now.
Not sure you can put Quinton de Kock in that bracket though...
SA 119-2published at 21 overs
Here's Moeen Ali to try and make something happen.
A tidy, if non-threatening, start as De Kock and De Villiers are happy to just dab him around for five off the over.
SA 114-2published at 20 overs
AB de Villiers brings up his first boundary, rocking back to cut a short ball from Adil Rashid away through backward point.
South Africa are picking up seven runs an over with consummate ease at the moment, stifling England and the crowd.
SA 107-2published at 19 overs
Prior to this innings, De Kock had a conversion rate of 50% in ODIs, having scored 12 centuries and 12 half-centuries.
He's showing no signs of letting up here either, as another exquisitely-timed punch down the ground beats the man and rolls away for four.
SA 100-2published at 18 overs
Tidy response by Adil Rashid, just five singles off the over as the tourists bring up the 100,
50 for De Kockpublished at 17 overs
SA 95-2
Image source, Rex Features...and there's a half century for Quinton de Kock, off exactly 50 balls.
The keeper-opener guides one down to third man to reach the mark.
It's been an excellent innings so far and should he convert it to a century, you have to think South Africa will chase down this target or get mightily close at least.
The tourists will be wary that they were on target for a long time at Headingley too though, but lost wickets at key times.
SA 94-2published at 16.4 overs
South Africa captain AB de Villiers strides out to the crease. How England would love to snare him cheaply here.
A watchful start from ABDV, dabbing one into the leg side for a single to get off the mark.
Here's Quinton de Kock on 49...

Vic Marks
Ex-England spinner on BBC Test Match SpecialThat's timely for England. Should you play that or not? It's a length ball just outside off stump. He might have been thinking about dabbing down to third man, but it ended up as a horrible prod.

Du Plessis c Buttler b Plunkett 16 (SA 93-2)
Liam Plunkett certainly isn't going to let South Africa dominate - a lovely ball, in that teasing area outside off stump and Faf du Plessis knicks it through to Jos Buttler.
The South African had played some nice shots for his 16, but just prodded forward to one without enough conviction and it tickles the edge.
SA 93-1published at 16 overs
Well Rashid does provide a bit more activity, but unfortunately for the hosts, it's a long hop that Faf du Plessis pounces on to pull for four.
There's a long way to go, of course, but England need to be careful this doesn't start drifting away from them too soon.
