“We have worked very hard over the last few months to get to this stage, so we want to make the most of it.”
The fitness of South African captain Temba Bavuma remains a matter of concern after suffering a hamstring injury against Afghanistan.
But Bavuma is expected to play on Thursday after batting in the nets at the Eden Gardens.
South Africa’s batting has been excellent in the World Cup.
Opener Quinton de Kock’s 591 runs is second only to Virat Kohli’s 594 runs.
The 30-year-old De Kock, who will retire from One Day International cricket at the end of the tournament, has four centuries to his name.
One of them came against Australia in the group stage.
