Sri Lanka won the toss and decided to bat in the third one-day international at Chevrolet Park here on Tuesday.
South Africa, leading the five-match series 2-0, made two changes from the side that played in the first two matches in Paarl and East London.
Alviro Petersen and Colin Ingram replaced Hashim Amla, who is on paternity leave, and Jacques Kallis, who is being rested for the remainder of the series.
Sri Lanka, needing a win to revive their hopes of winning the series, named the same side that was beaten by five wickets in East London on Saturday.
