Sri Lanka had collapsed to 239 all out shortly after lunch on Thursday, in the deciding Test against South Africa at Newlands.
South Africa enforced the follow-on as the deficit is 341 runs.
Morne Morkel bowled the last over of the innings which was a good indication of captain Graeme Smith’s intentions.
Sri Lanka lost the key wicket of Kumar Sangakkara early when Dale Steyn struck with his third ball of the morning.
The batsman was caught flashing outside off-stump and Hashim Amla, at point, dove to his left for the catch to remove Sangakkara for 35.
Mahela Jayawardene and Tilan Samaraweera added 36 runs together before Samaraweera (11) got an outside edge to Vernon Philander which flew low to Jacques Kallis at second slip.
Philander bowled a magnificent six overs in his morning spell, conceding only three runs for his wicket.
Steyn came back into the attack and sent Jayawardene (30) on his way, giving Kallis his second catch off a thick edge to second slip.
One of the stars from the Durban Test, Dinesh Chandimal, the wicket-keeper who scored two half centuries on debut in that match, joined Angelo Mathews at the crease but the partnership did not last long as Mathews (5) departed, caught behind off Steyn.
Thisara Perera fell just before lunch giving Imran Tahir his second scalp of the innings.
Sri Lanka were all out just 29 minutes after lunch when Chandimal (35) was caught behind off Morkel. – Sapa
