A record third-wicket stand from Rilee Rossouw and Hashim Amla set South Africa on their way to a 131-run victory over West Indies as they rounded off preparations for the Cricket World Cup in style.
In a match shortened to 42 overs due to rain, South Africa blitzed 361-5 in Wednesday's fifth and final one day international in Centurion.
The majority of that total came from the 247 put on by Rossouw and Amla, the highest third-wicket partnership for South Africa in ODIs, as West Indies could only muster 230 in reply.
Rossouw (132) reached his hundred in just 83 balls, the 12th fastest by a South African, while Amla - standing in as captain for the rested AB de Villiers - smashed 133 off 105.
Wayne Parnell (4-42) then tore through the West Indies middle order, leaving the visitors counting the cost of a 4-1 series defeat.
South Africa started slowly as Quinton de Kock (4), making his return from ankle ligament damage, handed Jonathan Carter an easy catch at point off Jason Holder's (2-77) bowling in just the second over, before Faf du Plessis (16) failed to trouble the scoreboard.
After 20 overs, the Proteas were on a comfortable 105-2, but then Rossouw and Amla started their blitz.
Rossouw took time to get going before smashing 23 off Andre Russell's (3-85) sixth over.
The left-handed batsman slowed as he neared his century, but once he passed the landmark he unleashed a barrage of huge shots - scoring two fours and two sixes off Holder in the 37th over.
At the same time, Amla once more oozed class with the bat and his knock took him to 413 runs for the series at an average of 206.05.
Rossouw eventually fell when he pulled Russell to Carter at deep mid-wicket, while the same man tempted Amla to drag onto his stumps.
David Miller (23) and JP Duminy (18 not out) boosted the scoreboard, before West Indies made an awful start in reply when Chris Gayle fell for a golden duck.
Dwayne Smith (31) and Narsingh Deonarine (43) steadied the ship, before Marlon Samuels (50) and Denesh Ramdin (40) put on 91 for the fourth wicket.
When Samuels was bowled by Kyle Abbott in the 28th over, though, the collapse began as Parnell tempted Ramdin with a short ball that produced a stunning catch from Amla at mid-wicket.
Parnell also claimed the scalps of Carter (0), Russell (24) and Holder (0) as West Indies collapsed from 176-4 to 230 all out.
