South Africa secured their seventh successive win after beating Pakistan by 10 wickets on day four of the second Test at Newlands to seal a 2-0 series win.
Pakistan, who had to follow on after being bowled out for 194 in the first innings, fought hard to avoid an innings defeat by just 10 runs after Saim Ayub was injured on day one, leaving South Africa just 58 runs away from victory.
David Bedingham and Aiden Markram were bowled out in just 7.1 overs to seal the series with a narrow two-wicket win over Centurion, also inside four days.
Since beating the West Indies by 40 runs in Providence last August, South Africa have registered a 2-0 series win over Bangladesh, Sri Lanka and Pakistan and qualified for their first World Test Championship final in June in London.
Ryan Rickleton's 259 in South Africa's crucial first innings total of 615 was named man of the match, but he did not take the field on Monday due to a thigh injury.
Pakistan's long resistance on a dry, flat pitch was largely based on a determined century from captain Shan Masood, who batted for more than six hours before falling to 18-year-old debutant Koena Mafaka after lunch.

South Africa have secured their place in next year's World Test Championship final at Lord's with a double win over Pakistan in Centurion.
Pakistan started the day on 213-1, with night-keeper Khurram Shahzad frustrating South Africa in the morning before being stopped by Marco Janssen on 18. Janssen came close to dismissing Kamran Ghulam without scoring in the process but Bedingham missed an easy chance. First slip.
Ghulam hit four boundaries on 28 but was undone by Kagiso Rabada off a delivery that had just come back enough to hit the off-stump when the batsman attempted a loose drive and missed the line of the ball.
The Proteas took possession of the new ball after lunch and batted twice in the next two overs.
Rabada found the outside edge of Saud Shakeel on 23 and the left-hander fell into the slips, and then South Africa got the big wicket of Masood. A successful lbw referral showed Maphaka's sharp shot hitting the Pakistan captain on the front board.

Masood helped reduce the deficit to 109 but Pakistan were five wickets behind with only four wickets remaining.
Salman Ali Agha (48) and Mohammad Rizwan (41) survived close lbw reviews early in their innings before spinner Keshav Maharaj, who bowled long overs on Monday, dismissed both batsmen.
No. 9 batsman Mir Hamza (16) smashed Rabada for six in a row before being the last bowler out, edging the pacer who finished with 3-115.
Maharaj (3-137) and Janssen (2-101) also helped as South Africa had to grind out 122.1 overs.
Bedingham opened the batting for the Proteas in the absence of the injured Rickelton and hit 44 off 30 balls with four boundaries and two sixes.
