Moeen Ali took three quick wickets to seal a comprehensive 241-run victory for England over South Africa in the first Test at Kingsmead on Wednesday.
South Africa began day five in deep trouble on 136-4 in Durban, chasing a mammoth 415 for an unlikely win, and lost four wickets for the addition of just seven runs before being bowled out for only 174 as Steven Finn (4-42), and Moeen (3-47) in particular, wreaked havoc.
The writing was on the wall for the Proteas when spinner Moeen pinned their key man AB de Villiers (37) lbw with just the third ball of the day.
Temba Bavuma (0) followed two overs later when he got an attempt to come down the pitch to Moeen all wrong, handing Jonny Bairstow an easy stumping chance.
South Africa were reeling, and England's day-four hero Finn then got in on the act with a sensational delivery that cleaned out Dale Steyn's (2) off stump.
Kyle Abbott (2) quickly became Moeen's third victim of the morning when he was trapped in front to leave the hosts 143-8.
The procession of wickets continued when Dane Piedt became Chris Woakes' first victim of the match for a 27-ball duck, inside-edging onto his pad to enable James Taylor to take a simple catch at short leg.
JP Duminy (26 not out) played some elegant drives in a last-wicket stand of 19 before Stuart Broad (1-29) finished off the job by dismissing Morne Morkel (8) lbw to wrap up an emphatic victory.
South Africa, the top-ranked team in Test cricket, have just a few days to regroup before the second Test in the four-match series starts at Newlands on Saturday.
