South Africa beat Pakistan by nine wickets on the fourth day of the second Test at Newlands on Sunday.
Pakistan claimed a wicket and forced Hashim Amla to retire hurt before South Africa passed their meagre target after less than an hour's play at Newlands.
Set 41 to win, South Africa reached 43 for the loss of one wicket from 9.5 overs.
The result ensured a seventh successive home series win for South Africa, who won the first Test in Centurion by six wickets. The third and final Test starts in Johannesburg on Friday.
Regular South African opening batsman Aiden Markram did not bat after suffering a severely bruised right thigh when he fell heavily on the boundary rope while fielding on Saturday.
Theunis de Bruyn, opening in place of Markram, clipped Mohammad Abbas to the midwicket boundary but did not add to his score before being caught off his glove by wicketkeeper and captain Sarfraz Ahmed while attempting to pull a bouncer from Abbas.
