Batting coach Dale Benkenstein believes South Africa need to adjust to the World Cup pressure and put up an improved performance with the bat to bring their campaign back on track following three successive defeats.
South Africa suffered losses against England, Bangladesh and India before getting their first point of the World Cup following a washed out match against the West Indies on Monday.
"The message is that the batters have got to step up and we haven't. I feel like we are batting well but we just haven't done it long enough. Everyone has got in. We have had opportunities to have hundred partnerships and win matches but we haven't done it," Benkenstein was quoted as saying by ICC website.
"We try and play quite an aggressive form of cricket. Scores are much higher than they used to be. Teams are scoring big totals so when you are in and you are dominating, you've got to try and make the most of it.
"Sometimes we don't get that balance right. We try and accelerate maybe a bit too fast rather than getting our heads down and ticking it over and the batters getting us more to the end of the game," Benkenstein added.
South Africa next will play Afghanistan in Cardiff.

Given the format of the tournament, where each team plays the other nine sides only once, Benkenstein said spontaneous planning could be the key in their remaining five games of the league stage.
"The difference in tournaments to international cricket is that in regular series you play the same opposition four or five times so you have an opportunity to start slow, to sum them up and then you can take them down," he said.
"Here, you are playing one-off games. You are playing on different wickets and against different teams in every match."
