Zimbabwe's radar is still leaving a little to be desired here, Chigumbura fires in the fifth wide of the innings - no mucking around, these are proper legside wides. De Villiers is moving up through the gears, taking singles at will - Du Plessis is playing the supporting role to his skipper, though their speed between the wickets bring them a well-run two to long leg off the last ball.

"You just wonder how South Africa would have gone in the innings if some of those shaky early shots from these two, especially AB de Villiers, went to hand. That would have been a body blow to this team. Suddenly, in the last 10 minutes, they look more settled and are generating more control out there."

Steady bowling from Mire, steady progress from South Africa, though Zimbabwe have posted a man out at long-on. Four singles and a two from the over, while Mire adds a wide to the score. There are plenty of Zimbabwe fans in the ground, and some are showing off their dancing skills.

New Zealand are flying as they chase a target of 218 to beat England in the third women's one-day international. The White Ferns are 47-0 after eight overs in Tauranga.

"South Africa are starting to build something now. AB de Villiers is trying to up the pace - he wasn't happy with the opening 10 overs. If he gets set then I think we're up for a treat."

Captain Elton Chigumbura - briefly an overseas signing at Northants a couple of years ago - brings himself into the attack as Zimbabwe's fourth right-arm seamer. More careful accumulation from the Proteas third-wicket pair, but when Chigumbura drags it down too short, De Villiers swats him for four through mid-wicket, earning himself a burst of "Smooth Operator" by Sade over the ground PA system. A single takes ABDV to 13 from 19 balls - positively tortoise-like by his own high standards...

Zimbabwe make their first bowling change and turn to the medium pace of Solomon Mire - apparently pronounced "Mirr-ray" - in place of Chatara. South Africa find easier pickings against him, with De Villiers and Du Plessis picking up some ones and twos.

And a snippet of news from MCC - they've awarded honorary life membership to former India captain Sourav Ganguly, an honour he shares with fellow ex-skippers Sachin Tendulkar, Rahul Dravid and Kapil Dev.

"Panyangara has mixed things up well. He is not the quickest but has put the ball into good areas. He has found a little bit of swing and his team will be happy with him. Now might be the time to switch things around."

Iain: Great start for Zimbabwe. Could be a real shock on here...

Panyangara stays on for his sixth over, and South African hearts are in mouths as Du Plessis nearly gives away his wicket, chipping the ball towards mid-off - the ball lands just in front of the diving fielder, but that was nearly three down for under 30. Two singles from the over, Panyangara has 1-17 from six.

Sunday Times cricket correspondent Simon Wilde: That celebration by Panyangara won't be bettered at this World Cup. Falls over in delivery and proceeds to massage the ground with his groin.

If you're just joining us, I can assure you the scorecard is working perfectly - South Africa are two down, for not many, against Zimbabwe. Yes, Zimbabwe. Du Plessis dabs a single, and De Villiers - having played himself in for eight dot balls - comes down the track and effortlessly lifts Chatara for six over long-off to get off the mark. Which, when you're as naturally talented as ABDV... is probably the completely logical thing to do.

That's it for the first powerplay - but with the Proteas on the rack, you may not see too many field changes next over, even with the restrictions lifted.

"Zimbabwe have bowled nice and tightly, and in good areas. They look like they have got a spring in their step, as you would expect from those two wickets. They look organised."

Zimbabwe have got South Africa rocking here - but the second wicket brings captain AB de Villiers, rated by many as the best batsman in the world on current form, to the crease. He sees off the rest of the over.

"That has got to be the best celebration I've ever seen! Panyangara has got Amla through the gate - Zimbabwe are flying. He backed off the length, put pressure on him and Amla could have been more definitive with the shot, he was a bit loose."

Listen to TMS commentary via the audio icon at the top of the page, or the "Live Coverage" tab.

Bowled him! Panyangara induces an inside edge onto his stumps from Amla's tentative prod, and having collapsed to the turf, the bowler celebrates by wriggling like an electric eel!

As seems to be the modern trend, the umpires advise Amla to walk off slowly while they check for a no-ball - something that doesn't seem to be done on-field any more - but he can only trudge off and South Africa are two down.

Chatara, emboldened after coming close to dismissing one of the best batsmen in the world, seems to find an extra yard of pace as he pings in a bouncer and Amla weaves out of the way. Only a single off the last ball prevents a maiden.

"Amla often doesn't ask his batting partner for their thoughts - he usually just walks with his bat under his arm. But on this occasion he was right to review the decision."

So it goes upstairs to third umpire Paul Reiffel - Amla has stepped across his stumps as he usually does, but is it too high? Yes - the ball-tracker shows it sailing over the top of middle stump. Amla - who's not normally a "reviewer" according to Neil Manthorp on TMS - survives.

"My gut feeling was that it was a little bit high. But if Zimbabwe are able to get this breakthrough it would be massive. But it is worth a review."
