Gayle seems to fancy the pace that Tsostobe is dishing up. The imposing left-hand batsman is opening up and swing for the leg-side. The powerplay comes to an end without too much damage done.
Steyn strays onto the pads of Charles, who clips it straight to Duminy at square-leg. The Fielder drops the catch and Charles lives to fit another day. Will that miss come back to haunt the Proteas.
Gayle is given a hint of width and Tsotsobe is deposited over mid-off for a boundary. It is an old fashioned contest between bat and ball and boundaries and play and misses are both coming.
Steyn comes into the attack. He bowls to Gayle, this is the contest that so many have been waiting for. 1-0 to Gayle as the first ball goes straight back down the ground for four. Steyn comes back well and his pace is consistently above 140km/h which is pleasing after an injury. The last ball of the over see's the bowler put down a tough return catch, the result is two runs to Gayle.
Tsotsobe takes the other new ball and beats the outside edge of Charles. A decent start for the bowler as the pitch offers just a little bit for the new ball bowlers.
South Africa through a curve ball straight away as the spinner, Duminy, opens the bowling. There is no turn and Charles plays a square-drive for four as the ball skids onto the middle of the bat. A good start for the West Indies.
Some very good batting combined with wayward new ball bowling has resulted in South Africa reaching 230 off their 31 overs. That is a very good total and you would back the Proteas to defend it 9 times out of 10. There is a man in West Indies line-up however, by the name of Chris Gayle. If he comes off then he could almost single handedly win this game. A light rain has started to fall, so it remains to be seen if the game will be reduced further. If it stays the way it currently is, then South Africa will be the clear favourites when they come out to bowl.
The captain decides to bowl the final over. WICKET. Faf is run out by the bowler as he thinks about stealing a quick leg-bye. The new batsman, McLaren, doesn't waist any time as hi top eadges his first delivery for six. WICKET. Miller miss hits and ii loops to cover. The rain has started to fall again, but the innings will be completed.
Miller swings Pollard into the leg-side and Sammy drops the catch. Two runs is the result. It proves costly as the next ball gives a catching chance to a member of the crowd. A very slow ball gives du Plessis enough time to adjust his stroke several times before slapping it to the boundary.
Bravo takes the responsibility to bowl the final over of the powerplay. Miller finally catches up with a slower bowl and picks up two runs to bring up the 200. His timing then returns and a six sails into the crowd in is favourite mid-wicket area.
Pollard comes back to face the music. Faf runs down the wicket, gets a top edge and earns four runs. The bowler is really mixing up his pace in an attempt to stop the batsmen lining him up. A very good over for the West Indies.
The batting powerplay has been called. We could be in for some fun. de Plessis backs away and hits a six over long-off while sitting on the back-foot. Not a very pretty shot but absolutely effective.
Narine is the bowler chosen to bowl 7 overs. I suggest that after the batsmen see him off, it could be time to cut loose in the last 5 overs of the innings. Six, it looks as if its time to cut loose already. Miller slaps one off the front-foot over long-on.
Rampaul opperates with the fielders right on the edge of the ring, so their is a run available off every ball. Miller will have good memories of facing Rampaul from the IPL where he scored tons of runs.
Narine starts his 6th over and South Africa still appear content to milk him for singles, even though the innings is coming to an end. A very tight over yields just three as the batsmen struggle to pick which way it is spinning.
WICKET. Rampaul comes back into the attack and immediately drops shot. AB smashes it into the leg-side and it amazingly caught, one-handed, by the mid-wicket on the edge of the ring. Miller is the new man to the crease. He has had a poor tournament thus far and owes his team some runs. The West Indies have down well by taken wickets everytime it looks as if things might be getting away from them.
Narine comes back into the attack as the South Africans look to be making their move. The 150 comes up as an easly single is taken to rotate strike. One of the main goals for the batsmen will be to face as few dot balls as possible and boundaries will be a bonus.
Bravo is picked off as the total continues to grow nicely for the Proteas. the final delivery of the over is dug in short and de Villiers cracks it through mid-wicket with some serious power.
Pollard continues after a successful first over. South africa will need to rebuild after a couple quick wickets before the onslaught at the death begins.
Bravo has another go with ball in hand. The run rate should slow slightly again as the new batsman tries to find his feet. WICKET. Duminy gets a glove down the leg-side and is caught by the keeper. Faf is off the mark with a sweet cover drive.
In an attempt to change his teams fortune, Pollard is getting a chance to bowl. If he drops short on this wicket, with his lack of pace, he could go the distance. WICKET. A special innings comes to an end. Ingram drags the slower ball straight to the man on the leg-side boundary and is on his way.
Tino Best comes back into the frame. The pace flies for six off the top edge as de Villiers attemps to take on the short ball. A crisp drive ends the over on a high as AB collects a boundary through cover.
Narine is consistently too short. This allows the South african batsmen to read the spin of the ball off the pitch and still have enough time to adjust their shot.
Samuels continues after taken the only wicket to fall thus far. The off-spinner drops short and its easily cut for four runs by Ingram. Another short ball finds its way to the boundary and the 100 comes up for the Proteas.
Narine comes back into the attack. If he can get rid of de Villiers before he gets in, then the West Indies will be right back in this contest. The bowler drops short, Ingram gets the edge but it is enough to get to the boundary.
Samuels comes into the attack to change the pace. WICKET. Amla hits a drive straight to cover. Gayle juggles it, but completes the catch on the third attempt. de Villiers is the new batsman and takes a single to get off the mark first ball.
Ingram goes down town. He hits Sammy for a straight six. Sammy drops short after been hit for six. He just isn't quick enough and Ingram helps himself to a boundary, which brings up a wonderful 50.
Bravo bring himself on in an attempt to make something happen. The West indies can't allow these opening batsmen to simple go along their marry way, or they will find themselves chasing a very big target. Both batsmen are now timing the ball sweetly.
The ex-skipper, Darren Sammy, comes into the attack. His lack of pace could be targeted in this shortened match. Singles off every ball brings six from the over.
Another extra down the leg-side brings up the 50 opening stand. Amla does really well to dig out a Best yorker clocked at 150km/h.
Ingram hangs on the back-foot and plays the mystery spinner Narine off the pitch. The left-handed batsman advances and hits the ball out of the ground. The 4th umpire runs on with a box of new balls as the last one is out of here.
Best is quick and banging the ball in half-way down. The batsmen haven't been able to get a hold of one propperly. A succession of singles keeps the scoreboard ticking over.
Narine comes into the attack and will bowl the last of the mandatory powerplay overs. He finds the edge first ball, it beats slip and the result is two runs to Ingram. Athletic fielding in the covers in saving the West Indies some valuable runs.
Ingram free's his arms, slashing Rampaul for another boundary. The odd ball is seaming a long way off the deck, so this ia a very good start for South Africa. If a bowler gets it right and has a little luck then he could run through a batting order in these conditions.
Best has Ingram in his sights for the first time. He is too straight and clipped for three through mid-wicket. Amla is then given a gift on his pads and it flies to the leg-side boundary. After the first two quiet overs, the Proteas have got a wiggle on. The out-field is expectedly slow after all the rain that has fallen.
Ingram is under-way as he pulls Rampaul over square-leg for the first boundary of the innings. Some movement off the deck is causing some trouble, but 7 runs represents a much better over for South africa.
Tino Best shares the new ball and will have his first bowl of the tournament. He is really bending his back as the speed gun reads 149km/h. Amla is off the mark as he nudges a couple onto the on-side.
Rampaul opens the bowling in this shortened encounter. It takes a few balls but as soon as the bowler finds his length, Ingram is cut in half by some seam movement. Just two wides come from the opening over.
The match is scheduled to start at 13:30 GMT. It has been reduced to 31 overs a side.
After a heavy shower, the rain has stopped and the covers are coming off again.
18 minutes before the scheduled start, the rain is back and the covers are being dragged back onto the pitch.
Gayle, Charles, Darren Bravo, Samuels, Smith, Dwayne Bravo, Pollard, Sammy, Narine, Best, Rampaul. The West Indies have made two changes. Best comes in for an ill Roach and Smith comes in for Sarwan due to the changed conditions and amount of overs.
Amla, Ingram, du Plessis, de Villiers, Duminy, Miller, McLaren, Peterson, Morris, Steyn, Tsotsobe. The big news and only change to the team is that Steyn is fit and replaces Phangiso.
The wicket has been under covers for a few days and has retained some moisure. There is also some green grass which should encourage seam movement. It will be tough for the batsmen in the early stages of the innings.
After a three hour delay, the West Indies have won the toss and decided to bowl first.
The toss will take place in 10 minutes. The match will be 36 overs a side.
The rain has stopped and the covers are coming off again. It remains to be seen how long the break in the weather will last. If it stays clear then action could start within an hour.
The drizzle has returned as the frustration grows for players and fans alike.
The sun is out and the covers are coming off. If the weather holds then play will start in just under an hour and we should get just under 40 overs a side.
The rain will have to stop by 14:05 for the game to get under way at 15:05 GMT. This will allow enough time for a 20 over match to be completed. If however, it is still raining by this time then the match will be called off and South Africa will progress to the semi-finals.
The groundsman has just confirmed that as soon as it stops raining, it will take an hour for play to get under way. For the time being the rain is still falling, but we will continue to provide updates on the situation.
The coin was scheduled to be tossed 14 minutes ago. It is still drizzling firmly though and it looks as if we could be in for a significant delay.
The sky is grey, a light drizzle is falling and the covers are on the wicket. As a result, the toss and team anouncement has been delayed. In the event that no play is possible today, South Africa will progress to the semi-final due to a superior net run rate. We will keep you updated with any news that filters through from Cardiff.
Today's winner will book a semi-final berth alongside India - and the top two finishers in Group A. That said, if today's fixture is a washout, the Proteas will advance ahead of the Windies thanks to a superior net run-rate. Indeed, inclement weather is threatening this match.
