South Africa completed a 2-0 series win over the West Indies after winning the third Test by eight wickets.
The hosts had been set a target of 124 runs for victory going into day five and were 9/1 after Alviro Petersen was dismissed just before the close of play.
South Africa made light work of the target, chasing it down within the first session, losing just one wicket in the process.
Man of the series Hashim Amla hit the winning runs, finishing 38 not-out, but it was the man Amla shared the fourth-wicket partnership with, Dean Elgar who starred.
The 27-year old scoring his fourth test fifty, he hit seven fours and one six in his innings of 60 not out.
