Raza, having bowled three unthreatening overs for 19, comes off as Zimbabwe turn back to Solomon Mire who took 0-11 from two overs as first change earlier. He fires in another legside wide before Duminy carves a two to deep point and pushes a quick single wide of mid-off. More ones and twos extend this partnership to 38 - with Duminy having dominated his partner since he came in.

They've made a terrific start, no doubt about that, but at what stage should Zimbabwe attempt to go for the jugular again? This pair are starting to look comfortable for South Africa, and with plenty of overs in hand, they're still more than capable of posting a commanding total - and at the moment, Zimbabwe's spinners are virtually gifting them 4-6 runs per over. As if to prove my point, five singles are taken from Kamungozi's fourth over.

More middle-over accumulation as Duminy and Miller continue to knock Raza around Seddon Park for ones and twos with little trouble. Seven from the over picks the scoring rate up a little.

We're used to much quicker scoring rates from South Africa, but they belatedly take their score into three figures just before the halfway point of the innings as Miller pushes Kamungozi for two. It looks as though Chatara may be getting ready for a second bowling spell. Miller moves to 19 from 25 balls with a single, a delicate Duminy dab to third man takes him to nine from 16.

As Zimbabwe try to hustle through a few overs of part-time spin in the middle overs, South Africa are equally trying to hustle through for any available ones and twos, though the boundaries have dried up again.

Kamungozi - who will definitely be worth a place alongside West Indies' Andre Russell in the World Cup Mohicans XI - isn't getting much turn but with South Africa needing to rebuild, he's quickly through his over for the cost of only two runs.

Zimbabwe turn to opening batsman Sikandar Raza, a part-time off-spinner, as their seventh bowler. South Africa plunder four singles - I mentioned their deep battling line-up before the game, they may well need it today.

Two left-handers in to face the leggie as JP Duminy joins David Miller at the crease. Kamungozi, sporting a mohican-style haircut, is quickly through the rest of his over, just a single from it. Who'd have predicted this?

We're just under an hour away from the start of India v Pakistan in Adelaide (03:30 GMT) - we'll be switching our focus to that game fairly soon, but you can listen to both games via the BBC website.

"That is an absolutely excellent catch. It is a tough one, right on the boundary edge, but the smile on Craig Ervine's face as he jumped over the side of rope said everything - he knew he had that catch. He looked like a ballerina, stretching out and grabbing it. That's the biggest wicket today potentially."

ABDV gone - brilliantly caught by Craig Ervine at long-off! Ervine leaps in the air to take the ball in both hands, then throws it up again just before his momentum takes him over the line, walks over the rope and then hops back onto the playing area to complete the catch. We saw some terrific catches yesterday (including one in the crowd), but that was right up there with them. A great moment for leg-spinner Tafadzawa Kamungozi, it was only his second delivery.

"South Africa have not imposed themselves. They are almost waiting for Zimbabwe to stand aside."

Williams rattles through his third over, three singles from it.

Meanwhile, in the women's ODI, England have dismissed NZ captain Suzie Bates for 39 - New Zealand are 66-1 after 14 overs in reply to England's 217-9.

Sloppy from Cap'n Chigumbura, he starts the over with a no-ball which De Villiers helps away for a single. That means Miller to face the free-hit ball... which is a knee-high full toss, and the left-hander gratefully whacks it over cow corner for six.

Madness outside the Adelaide Oval. Reckon blue shirts outnumber green by at least five to one.

Left-hander David Miller is the new batsman, he's more used to coming in at 250-3 with licence to blaze away in the last few overs rather than having to come in with less than 70 on the board and help rebuild an innings. A familiar face to Yorkshire fans from a couple of stints of T20 blasting, Miller is off the mark with a single off his first ball. De Villiers takes some easy singles against Williams's left-arm spin - how South Africa could do with one of his record-breaking centuries now.

"That is one of those balls where do you really need to go out there? Du Plessis had moved across and got the faintest touch as he tried to glance it - that's a bonus for Zimbabwe. It puts more pressure on South Africa just as they were gaining some momentum."

But Zimbabwe bounce straight back with a strangle down the leg side - Chigumbura fires down a loose delivery and Du Plessis feathers an edge to the delighted keeper Brendan Taylor.

Scorecard

Zimbabwe, let's be honest, would have bitten your hand off if you'd offered them 59-2 at drinks after they'd won the toss. While Faf du Plessis and AB de Villiers are taking singles at will, there's not been a boundary since the seventh over... but Du Plessis ends that particular drought with a lofted six over long-off.

Our first sight of spin today as Williams is off after two overs, replaced by slow left-armer Sean Williams. Four singles from the over, and the players have earned some drinks.
