Kagiso Rabada ripped through England to earn South Africa a consolation 280-run victory in just over an hour's play on day five of the fourth Test at Centurion.
The 20-year-old seamer followed up his Test-best, first-innings 7-112 with 6-32 as the tourists tumbled from their overnight 52-3 to 101 all out - Alastair Cook's team winning the Basil D'Oliveira Trophy 2-1.
Rabada, the youngest South African to take 10 wickets in a Test match, finished with match figures of 13-144 - figures only bettered for his country by Makhaya Ntini's 13-132 against West Indies in 2005.
Any bullish hopes England harboured of taking the game to South Africa vanished as four wickets fell for just 25 runs inside the first 40 minutes of play.
The tourists added just four before Joe Root (20) was dropped by Quinton de Kock off Dane Piedt in the second over of the day, but the reprieve was to be short-lived.
Morne Morkel (3-36) started the rot with a short ball that James Taylor (24) gloved behind - the Nottinghamshire batsman finishing the series with a disappointing 186 runs at 27 - and with the score still on 58 Root snicked Piedt to Dean Elgar.
Ben Stokes and Jonny Bairstow briefly entertained but there was to be no repeat of the fireworks that produced a mammoth 399-run stand in Cape Town.
One delivery after being caught off a Rabada front-foot no-ball, Bairstow snicked through to De Kock to make it 83-6 - the seamer's third wicket of the innings elevating him to the leading wicket-taker of the series with 19 despite not playing in the first Test.
Stokes continued to take on the short ball despite receiving a painful blow in the midriff from Morkel and it proved his undoing, the all-rounder picking out Stephen Cook at deep square.
The procession continued as Rabada found Chris Woakes' edge and Stuart Broad was well caught by De Villiers at slip as the all-rounder threw his bat at the ball. Rabada needed just one ball at last man James Anderson to wrap up victory in double-quick time.
