We thought this was going to be one-sided because of the way Pakistan played against India. However, you can never really write Pakistan off because of their mercurial nature. They are number one in the world at surprising people.
Sorry to keep you waiting for so long but finally we have some news.
The umpires have had one last chat and decided enough is enough.
Pakistan win by 19 runs via DLS method.

Diddly Dennis: Re KAP (20:36) - it wouldn't be hard to do but you've have 20,000 fairly angry people who shelled out £50 a ticket!
Pakistan have shown a major all-round improvement in their performance since the India loss, but their fielding has just been on another level in comparison. Chalk and cheese.

Why is this a day/night match anyway? All the matches in a tournament in England in early June should start at 10:30am with an option of floodlights till 10:30pm if needed.

Pakistan's Hasan Ali was the pick of the bowlers for me. After the top four departed, he took the important wickets of Duminy and Parnell to leave South Africa reeling.
He finished with figures of 8-1-24-3

Michael Calverley: Win tonight and you cannot write off Pakistan, surely?! Winning ugly!
Several texts and tweets asking what is happening with the rain and whether we will see any more play.
We still have no update I'm afraid, but I will tell you as soon as we know.
In fact, let's see that wicket again but this time packaged together with the wickets of Hashim Amla, Quinton de Kock and Faf du Plessis.
The Pakistan bowlers powered through the South African top order.
So, what else interesting has happened today? Well, start spreading the news ... AB de Villiers was out for a golden duck.

KAP: Any chance that cricket can start a game early because rain is forecast? Surely that isn't hard to do?
Shoaib Malik showed every bit of his experience in them last few overs before the rain, making sure Pakistan were well above the DLS par score. Babar Azam has also stood firm in this innings.

Harry Bridges: Will the cricket be a draw?? Or will Pakistan win because they're ahead on the DLS?
As it stands, if play does not resume then Pakistan will win.They are 19 runs ahead of the DLS par score. More than 20 overs have also been bowled in this innings, so we will have a result.

As the Pakistan openers looked to be cruising in their run chase, enter Morne Morkel with two quick wickets.

I imagine the ICC have learned that matches where the ball is getting smacked all over are the matches people like to watch.

As has become the norm in this tournament, I will keep you entertained in the rain delay with some of the best clips from the day, updates on the weather and getting all your tweets and texts for reaction.
So, Pakistan are in a somewhat commanding position and they owe a bit of that to debutant Fakhar Zaman. The opener looked well placed on the international stage. He scored six boundaries in his 31 before South Africa made the breakthrough.

South Africa will want to get out there and try and win this game today - they won't want to be in a position where they need to beat India in their final game to reach the semi-finals.
