What that means is West Indies have sealed their place in the semi-finals in the World T20. South Africa are now relying on Sri Lanka to beat England tomorrow to keep their faint hopes alive.
Agonising stuff for South Africa and Hashim Amla! Ramdin scoops one out to third man and he makes the catch, but it trickles out of his grasp and rolls out to the boundary. Another hugely dramatic finish here.
West Indies beat South Africa by three wickets
Rabada looks too cause havoc on the final over but Brathwaite meets his second ball with a tremendous hit that flies into the stands for six! West Indies just need to keep their composure here, they need two from four.
19th over – West Indies 114-7
Samuels starts the over by meeting a slow ball with a tidy scoop over to the right that flies past the third man, his fifth boundary of the match. He is hauling them over the line at the minute, meeting Morris' ball with a terrific bottom edge. But if West Indies are to win this, it won't be with him on the field, off the next ball he heaves a big hit in the air but it is perfectly tracked by De Villiers who makes the decisive catch. West Indies need nine from the final over.
WICKET! Marlon Samuels (43 c AB de Villiers b Chris Morris
18th over – West Indies 103-6
Pressure is building on West Indies, effective bowling from Wiese limits them to just three singles. 12 balls left in this match.
17th over – West Indies 100-6
Huge, huge over for South Africa! Big let off for Samuels as he hammers Tamir's delivery straight back to the bowler, but it is too hot to handle and the opportunity is gone. South Africa get their wicket two balls later with Russell thumping one over midwicket where David Miller is on the spot. Darren Sammy is in to help but is on his way back out straight away, fooled by Tahir's googly. Tahir wants a hat-trick with Brathwaite in, but he misses out this time.
WICKET! Darren Sammy (0) b Imran Tahir
WICKET! Russell (4) c David Miller b Imran Tahir
Bit of a delay as we change balls here ahead of the 17th over. Four fours from Marlon Samuels has left the Windies with 24 of the win.
16th over – West Indies 99-4
Samuels hits another superb four, adjusting himself brilliantly before directing it down the line to move his side to within three runs of a 100 and 23 off the victory. He and Russell chalk up another single each.
15th over – West Indies 91-4
Four runs and no wickets taken in the 15th over, West Indies are inching their way there.
14th over – West Indies 86-4
Oh dear, Bravo. West Indies lose a fourth wicket as he lifts Phangiso's delivery comfortably into the hands of Wiese. South Africa are not lying down, here.
WICKET! Bravo (8) c David Wiese b Aaron Phangiso
13th over – West Indies 84-3
A much improved over from West Indies, Bravo marks his introduction with a smashing four past fine leg before Samuels gets in on the act, slicing one over that is just out of reach of de Kock. Off the next ball, Samuels meets it nicely again, lashing it past third man. Huge over for the Windies, that target of 123 now looks comfortably in their sights.
12th over - West Indies 70-3
Charles gets his next big swing wrong, lifting it high into the sky and de Plessis is well placed to catch. DJ Bravo comes in and he and Samuels add three more singles to steady the ship after that big wicket.
WICKET! Charles (32) c Francois du Plessis b David Wiese
11th over West Indies 66-2
More good fielding from Amla as he leaps onto Charles' low drive. There is nothing anyone can do about the next one, however. Charles lifts an enormous six 101 meters clear, the joint longest we have seen at the World T20. That eases the pressure on his side considerably.
10th over – West Indies 57-2
Charles paddles one down fine leg cleverly but West Indies still aren't finding the big fours and sixes they are used to. Charles one drills one out midwicket but South Africa are well positioned to scoop up and limit it to a single.
Ninth over – West Indies 51-2
Eighth over – West Indies 45-2
Seven from this over, Marlon Samuels rescues it with a tidy edge around the corner and out to the boundary. Lots of responsibility on his shoulders now with Gayle gone.
Seventh over West Indies 38-2
Lots of hesitation between Charles and Samuels, the former slaps Phangiso's ball away and it flies past the second man. West Indies settle for the single, however, when there was probably enough time to get back down the other end. Just one run in this over.
