South Africa have reduced Sri Lanka to 80-4 at stumps on day two of the third Test match in Johannesburg.
The Proteas have already won the best-of-three series but they look on course to make it a whitewash after taking four wickets in 28.4 overs on Friday.
South Africa had resumed on 338-3 and although they only added another 98 runs in reaching 426, Hashim Amla ended with a score of 131 and Quinton de Kock contributed 34 further down the order.
Sri Lanka needed a bright start to their innings but they lost Dimuth Karunaratne to the fourth ball of the innings off the bowling of Vernon Philander.
Kusal Mendis hit a valuable 41 but Philander and Kagiso Rabada ended the day with two wickets apiece to leave the tourists needing a strong performance on day three to get back into the match.
