New captain Shai Hope led the West Indies to a formidable total in the second ODI against the Proteas at Buffalo Park in East London on Saturday.
Hope made 128* in a total of 335-8 after he won the toss in his first match in charge.
Brandon King (30) and Kyle Mayers (36) gave the tourists a rapid start, putting on 67 for the first wicket off 8.3 overs. But they lost three wickets in 10 balls to be 71-3.
Hope shared partnerships of 86 with Nicholas Pooran (39) and 80 with Rovman Powell (46) before the innings lost impetus as the balls became softer on a slow pitch.
But Hope, coming in at No 4, batted through to finish the innings in a flurry of scoring and chalk up his 14th ODI century.
His runs came off 115 balls and included seven sixes and five fours.
South Africa fielded four new caps, including fast bowler Gerald Coetzee, who was his team’s most impressive bowler.
Coetzee conceded 18 runs in his first over but came back strongly to take 3-57 in 10 overs.
