Sammy: "Yes I was smiling because of the position the game was, but there were butterflies in there. We came here to win this match and qualify, and we've done that, so we're really happy."
Faf: "It felt like the whole game we were half a step behind West Indies and we were trying to catch up the whole time. 10 runs maybe more from the batters - 135 deck. But a great fight by the boys. This game makes us all very old, very quickly! West Indies were just a little bit better than us today. It was a little bit frantic that first six overs".
"We've been getting wickets in the powerplay," added Sammy, "and that's been putting pressure on the opposition. Today we were under pressure chasing a low total, and every decision we took out there they responded. But I really want to commend my team on [how my team coped with the pressure]."
11.20pm And that's it for our coverage. I'm Will Luke, and do join us tomorrow for another crucial encounter: England v Sri Lanka. If England win, they're through to the semis. It's all getting thoroughly interesting. Bye!
11.15pm I'm sure you're all dying to hear from the captains, so, hang on in there.
Marlon Samuels: "Sometimes you have to bat accord to situation," he says. The pitch was "a bit on the slow side [but] credit to South Africa, [they] bowled in good areas.
"The bowlers [West Indies] have been doing a wonderful job. Badree up front, then Benn. We have the power and have a mix of different players who [can rotate the strike]."
11.05pm Where this leaves South Africa is less certain, but it'll be almost impossible for them to qualify. Faf looks mortified - so he should be at posting such a lowly total - as the players all shake hands. We'll hear from the captains shortly.
And West Indies have qualified for the semi-finals of the ICC World Twenty20 2016
Ramdin on strike now - 1 from 3. South Africa have brought the field in. Brathwaite towers over Ramdin and has a chat with him mid-pitch
2 from 4
3 from 4
Rabada to bowl the final over
Good grief! 9 from the last over. It's not what we expected, really; I think we all felt 123 was fairly comfortable, didn't we?
Brathwaite on strike
10 from 7
Easy catch, that, to a pretty lazy stroke. 10
14 from 9. Samuels on strike. Two balls left in the over and Samuels will want the strike for the final over
Spiere: "Blockhole! Blockhole! Blockhole!!!"
15 from 10
16 from 11
20 from the last two overs. To be even clearer, 20 from 12. Crikey moses, it's getting tasty
A dot ball, ladies and gentlemen...
...but only a single
Massive over, that. He loves it, Tahir - quality bowler under pressure
He's on a hat-trick!
