Cape Town - Kagiso Rabada took four wickets on Tuesday morning - and 13 in the match - as South Africa cruised to a 280-run victory over England in the fourth and final Test in Centurion.
Despite the result, England win the series 2-1.
England started the day on 52/3 with Joe Root and James Taylor at the wicket, but it was not long before the Proteas had something to cheer on the final morning when a scorcher from Morne Morkel in just the third over of the day had Taylor caught behind for 24.
That was the start of the rot.
In the very next over Dane Piedt had Root caught at slip for 20 before Rabada got into the act when he dismissed Jonny Bairstow for 14 as the England wicketkeeper edged one through to Quinton de Kock.
That wicket gave Rabada his 10-wicket haul for the match and also made him the leading wicket-taker in the series.
Morkel then had the dangerous Ben Stokes caught behind for 10 and Rabada then dismissed Chris Woakes, also caught behind, for five.
The 20-year-old Rabada then had his second five-wicket haul of the match when he got rid of Stuart Broad for 2, and the Proteas quick claimed number six when he had James Anderson out LBW for 0.
South Africa need a little more than an hour on day five to wrap up the match as England were all out for 101.
Rabada's 13-144 is the second best all-time Test match bowling figures for South Africa behind Makhaya Ntini's 13-132 against the West Indies in 2005.
