South Africa earned a seventh consecutive victory after defeating Pakistan by 10 wickets on the fourth day of the second Test at Newlands to claim a 2-0 series victory.
Pakistan, forced to continue after being bowled out for 194 in their first innings, struggled to avoid an innings defeat with just 10 batsmen left after Saim Ayub was injured on day one, leaving South Africa just 58 runs to win .
David Bedingham and Aiden Markram broke the streak in just 7.1 overs to wrap up the series after their narrow two-wicket win at Centurion, also inside four days.
Since beating the West Indies by 40 runs in Providence last August, South Africa have claimed 2-0 series wins against Bangladesh, Sri Lanka and Pakistan to qualify for their first World Test final in June in London.
Ryan Rickelton's 259 in a decisive first innings 615 for South Africa earned him man of the match, but he did not take the field on Monday due to a groin injury.
Pakistan's prolonged resistance on a flat, dry pitch was largely based on a determined century from captain Shan Masood, who batted for just over six hours before falling to 145 off debutant Kwena Maphaka after lunch.

South Africa have guaranteed their place in next year's World Test Cup final at Lord's after a two-wicket win over Pakistan in Centurion
Pakistan started the day on 213-1 and nightwatchman Khurram Shahzad frustrated South Africa in the morning before being caught by Marco Jansen at the 18th over. Jansen came close to dismissing Kamran Ghulam for no hit at the same time, but Bedingham missed an easy catch at first slip.
Ghulam hit four boundaries in 28 but was undone by Kagiso Rabada after a delivery that only came back enough to hit the off stump as the batsman tried to drive loose and missed the line of the ball.
The Proteas took the new ball after lunch and struck twice in the next two overs.
Rabada found Saud Shakeel's outside edge on 23 and the left-hander was caught at slip, then South Africa got the big wicket of Masood. A successful lbw delivery saw Maphaka's sharp delivery hit the Pakistani captain in the front.

Masood helped reduce the deficit to 109 but Pakistan were five wickets down with just four remaining.
Salman Ali Agha (48) and Mohammad Rizwan (41) survived close lbw reviews in the early innings before spinner Keshav Maharaj, who bowled long spells on Monday, dismissed both batsmen.
No. 9 player Mir Hamza (16) smashed Rabada for successive sixes before being last out, outsprinting the pacer, who finished with 3-115.
Maharaj (3-137) and Jansen (2-101) also helped as South Africa were required to bowl out 122.1 overs.
Bedingham opened the batting for the Proteas in the absence of the injured Rickelton and hit an unbeaten 44 off 30 balls with four boundaries and two sixes.
