South Africa were going at five or six an over, but were letting the bowling dictate to them. Maybe the desire to change that was AB's downfall.

De Villiers c Kapugedera b Prasanna 4 (SA 194-3)
Hmmm, is this going to end like the New Zealand innings of yesterday? AB de Villiers, showing intent from the get-go, tries to hoick the leg spin of Prasanna across the line and gets an outside edge which loops to Kapugedera at cover.
This is like the creme caramel of fours.

It was a good knock by Du Plessis, laying the foundations for a dart for those coming in. The platform has been laid.
Pradeep 6-0-28-2
There's a group of Sri Lanka fans in the crowd, using a trumpet and some drums to create a little corner of Colombo in London. They're really good - and this is coming from a man who doesn't believe in musical instruments making their way into a ground. If I was ever to get married again - let's hope Mrs Higginson isn't reading this - I'd book them for a turn. Really good they are.
AB de Villiers - the number one ranked ODI batsman in the world - arrives with 16 overs to work his magic. Batten down the hatches, Brenda. Move your vehicle, Mick.

It's a short delivery that could have been hit anywhere. He might have been better going over point, but instead squirted it to mid-wicket and it was a very good catch.
Du Plessis c Chandimal b Pradeep 75 (SA 189-2)
Maybe the short stuff was all a plan, after all? Pradeep tests out the middle of the pitch, Faf's eyes light up and Dinesh Chandimal takes a diving catch at mid-wicket.

Sri Lanka's fielding has been a real mixed bag. We've seen a dropped catch, some fielders jumping over the ball and then a few Superman-like stops.
Prasanna 8-0-54-0
A good over from Prasanna - he of the short run-up and leg-breaks - goes for just four singles. Trevor McDonald is in the house. Bong!

We had a team meeting in New Zealand about how to play Chris Harris. Jacques Kallis had got some runs, so we asked him what he did. He said "I just try to use the outside half of my bat to work him for singles." Thanks for that, Jacques.
Amla 83 off 85 balls
Hashim Amla could make putting up flat-pack furniture look easy and graceful. He picks up a delivery from medium-pacer Gunaratne, off his pads, and the ball glides to the boundary.

Prasanna has the shortest run-up I've ever seen in world cricket. He's got some good drift.
Run-rate: 5.51
Everyone's predicting a South Africa onslaught - and it will probably happen - but the Proteas should be mindful that New Zealand were in a similar position against Australia before losing seven wickets for 37 runs.
Faf gets things moving with a well-timed cover drive which bisects two fielders on its way to the boundary.
I like big sixes and I cannot lie.
This man's come a long way from whacking bowlers round the park in the Lancashire League (back in his early days).

The South Africa 12th man just sprinted on. It might have been a little message to say that they have plenty of firepower left, so to get after the fifth bowler.
Television cameras pick out a crane winching a block of concrete up the side of a predominantly-glass skyscraper (I think it was The Shard). Slow and steady wins the race in these circumstances, although I imagine the conversation between the workers operating the crane might be: "Hurry up Bob, AB's in shortly. We don't want him sending 160g of leather our way."
Or maybe not. As you can probably summise from my nonsensical musings, things are a little stale out in the middle. Six from the over.

I don't think the outfield has been as fast for the England-Bangladesh game. There's been a lot more running.
Sri Lanka won the toss
Suranga Lakmal, I'm fairly sure, hasn't changed his hairstyle in a decade. It's sort of a messy mullet. If it works, and all that. I'm fully aware I'm on dodgy ground here since I've had a short, back and sides since being sent home from school for having tramlines shaved in back in 1997.
One thing which is different about Lakmal this time is his pace. He's touching 87mph but is also bowling far too short in these middle overs. The result is trampoline-like bounce which is being pulled rather easily by Amla and Du Plessis.

Du Plessis changed the tempo. He came out with a real intent. It's helped Amla. It was subdued from De Kock.
