South Africa won the toss and sent India in to bat in the third one-day international at Newlands on Wednesday seeking to get back into the series.
With India having won the first two matches comfortably by chasing down targets, South African captain Aiden Markram admitted: "We understand India do chase well but we think there might be a bit of assistance for the bowlers up front and then it should be a very good wicket."
Indian captain Virat Kohli said: "We wanted to bat first, to change things up a bit. It looks a good batting track. We thought it might do more under lights with two new balls."
Kohli said India wanted to post a good total and then challenge an inexperienced South African batting line-up to chase a target.
India were unchanged for the third successive match.
South Africa made three changes.
Markram was due to open the batting, as he does in Test matches and domestic one-day games, following a wrist injury which ruled Quinton de Kock out of the rest of the series, as well as three Twenty20 internationals which follow the one-day matches.
Heinrich Klaasen, 26, will make his international debut, taking over the wicketkeeping gloves from De Kock and batting in a middle order severely weakened by injuries to AB de Villiers and regular captain Faf du Plessis.
Klaasen toured New Zealand last year as back-up wicketkeeper but did not play in a game. He is a capable batsman who scored 522 runs at an average of 52.20 in South Africa?s recently completed domestic one-day competition.
Fast bowler Lungi Ngidi, who has already played in Tests and Twenty20 internationals, was making his one-day international debut in place of Morne Morkel, while all-rounder Andile Phehlukwayo replaced wrist spinner Tabraiz Shamsi.
