This is the first boundary of the match, superbly cut away by Quinton de Kock.
Mustafizur Rahman continues as the reprieved Reeza Hendricks smashes the ball through the covers for his first boundary of the match.
Every run he scores will sting more and more for Bangladesh.

It wasn't the sort of slip catch they were anticipating because it was off the back foot and it wasn't a great ball to be honest.
How expensive might that prove to be?
Reeza Hendricks dropped at slip! The South Africa opener goes for a cut shot off the back foot and a thick edge flies to Tanzid Hasan at first slip, but the ball squirms from his grasp.
Potentially a huge moment.
Lovely shot from Quinton de Kock as he pounces on a wide delivery from fellow left-armer Mustafizur Rahman and cuts the ball away square for four.
We will have some spin opening at the other end as offy Mehidy Hasan Miraz limbers up.
Quinton de Kock and Reeza Hendricks are out in the middle on what looks another stiflingly hot day in Mumbai.
Mustafizur Rahman will open the bowling for Bangladesh.

South Africa will just want to replay exactly what happened here three days ago against England.
Just the one change per side. Lungi Ngidi has a minor knee issue so Lizaad Williams comes in for his second one-day international appearance.
As we know Bangladesh have captain Shakib Al Hasan back, he comes in for Towhid Hridoy.
South Africa: Quinton de Kock, Reeza Hendricks, Rassie van der Dussen, Aiden Markram (c), Heinrich Klaasen, David Miller, Marco Jansen, Gerald Coetzee, Keshav Maharaj, Kagiso Rabada, Lizaad Williams.
Bangladesh: Tanzid Hasan, Litton Das, Najmul Hossain Shanto, Shakib Al Hasan (c), Mushfiqur Rahim (wk), Mehidy Hasan Miraz, Mahmudullah, Nasum Ahmed, Hasan Mahmud, Shoriful Islam, Mustafizur Rahman.

We heard on Sunday that Temba Bavuma was progressing well and we saw him warming up with the first-choice bowlers this morning and we all thought he was going to play.
Reeza Hendricks has been in very good form. I wonder if this is just another opportunity if Bavuma is just a little bit under the weather still.
Bangladesh captain Shakib Al Hasan: "I’m fully fit.
"Beating them in 2019 and having a good record against them generally will give us a lot of confidence but today is another game, another venue and another pitch and we’ll have to play our best cricket.
"We wanted to bat first as well but I don’t mind bowling first as well. Hopefully we can restrict them to a reasonable total and chase it down."
South Africa captain Aiden Markram: "We will try and approach the game in a similar way to the England game. The wicket looks familiar."
On fielding later in the day in cooler conditions: "It will certainly help. It's really hot. The previous game against England took its toll on everyone in the middle, so it gives us a slight advantage."
On beating England after losing to Netherlands: "It proves that anyone can beat anyone and there is no such thing as an easy game. We took lessons from the Netherlands game and bounced back against England. But today is a new day and we have to respect the game of cricket."
Aiden Markram wins the toss and decides to have a bat first. No real surprise given the searing heat in Mumbai.
The good news for Bangladesh is that skipper Shakib Al Hasan is fully fit, but South Africa are still without their regular skipper Temba Bavuma as it is Aiden Markram who is in the middle for the toss.
Afghanistan and Pakistan treated us to a thriller on Monday as this World Cup becomes increasingly unpredictable.
