A combined knock of 265 from South Africa's Hashim Amla and Rilee Rossouw led the hosts to a score of 361-5 in the fifth and final one-day international against the West Indies.
The Proteas have already sealed the series after winning the first three matches and were in confident mood in Centurion this evening.
The Windies got off to a good start when they removed opener Quinton de Kock (4) and number three Faf du Plessis in the opening 10 overs, but then the Amla-Rossouw partnership took hold.
The pair put on 247 runs in a record third-wicket stand. Rossouw smashed 132 off 98 balls with nine fours and eight sixes, while Amla went one run better with 133 off 105 balls.
Andre Russell took the wickets of both, but it didn't really help the tourists as David Miller (23) and JP Duminy (18) came in and added quick runs at the end.
