Wicketkeeper-batsman Quinton de Kock hit an attacking 87 to guide South Africa to a four-wicket win over Sri Lanka in the second One-Day International here on Wednesday.
Chasing 245 for victory, the visitors rode on a 91-run opening partnership between de Kock and Hashim Amla, who scored 43, to win with more than seven overs to spare.
South Africa takes a 2-0 lead in the five-match series.
Skipper Faf du Plessis contributed with a valuable 49 after Sri Lankan spinner Akila Dananjaya led the bowling charge to give the visitors some trouble.
The Proteas bowlers also played their part earlier as pacemen Lungi Ngidi and Andile Phehlukwayo claimed three wickets each to restrict Sri Lanka to 244 for eight.
Angelo Mathews made 79 and Niroshan Dickwella 69 to give the Sri Lankan total some respectability.
