Quinton de Kock already has two centuries in this World Cup.
He's half way there to another.
Screams of "catchhh" from the Bangladesh fielders as Aiden Markram drives just past the reach of extra cover.
It was a full length dive but he couldn't get to it.
A hint of encouragement for Bangladesh.

Bangladesh are making it tricky for South Africa - 14 of the first 20 overs have been spin. That tells a story.
Thanks Tom.
This partnership of 63 has settled some nerves in the South Africa changing room.
Another bowling change and it is another spinner in Mahmudullah, who races through his six deliveries at the cost of just a single.
With South Africa having recovered from those two early wickets it is time for me to take a break.
I'll leave in the safe hands of Callum Matthews.
Quinton de Kock continues on his merry way as he hammers a short ball from Nasum Ahmed away through cover.
De Kock has ruthlessly punished any bad balls from Bangladesh so far.
Quinton de Kock was out for just four against England on Saturday. He looks keen to make up for that today.
SA 92-2
Quinton de Kock adds another two to his score with a cut shot that is well cut off by the boundary rider.
A further single completes another fruitful over for South Africa, who are warming to their task.
The end of the over signals a well-deserved drinks break. It looks sweltering out there.

Quinton de Kock is back in the runs again but Mustafizur should have stopped that. He got there, he'd done everything right but the ball got through.
A single brings Quinton de Kock and he brings up his half-century off just 47 balls with a clip fine off the pads that is fumbled by the fielder at fine leg and flies away to the boundary.

That's a genuine edge and Shakib Al Hasan needs to look at if he can get a slip in place. Had there been, he might have been in business.
Frustration from Hasan Mahmud as he gets a hint of seam away from Aiden Markram and finds an edge, but with no slip in place the ball runs away for four.
Unlucky.

Bangladesh have done well. I think they've done a really decent job, if they can just squeeze a wicket or two here then they can really put South Africa under pressure.
Another change of bowling and it is more spin as slow left-armer Nasum Ahmed comes into the attack.
Just the three singles come off it, with Quinton de Kock now three runs away from a very measured half-century.
Ten came off that over from Hasan Mahmud, the most expensive of the innings so far.
Quinton de Kock is efficiently picking off the bad balls, with no real risky strokes.

That is a massive hit. Leaning back and heaving it over square leg.
Quinton de Kock is in good touch.
A short ball from new bowler Hasan Mahmud is seized upon by the Proteas opener and pulled powerfully away over square leg for six.
De Kock has quietly moved on to 38 from 42 deliveries. He failed with the bat against England on Saturday while most of his team-mates ran riot, so appears in the mood to make amends today.

High and handsome. An effortless shot from Quinton de Kock.
That's more like it.
Quinton de Kock skips down the track and calmly dispatches a delivery from Shakib back over his head for six.
