India's win was set up by 115 from opener Rohit Sharma _ his first significant score of the tour _ and sealed by wrist spinners Kuldeep Yadav and Yuzvendra Chahal, the standout bowlers in the series and constant thorns in the side of the South African batsmen.
India's first success in an ODI contest in South Africa also came with a game to spare. The tourists could stamp their dominance even further with a potential 5-1 win over the team that was ranked No. 1 at the start of the series.
India is now top-ranked in ODIs and there's no doubting that after this performance. India has won nine straight series, and last lost one in Australia in early 2016.
India's only failure in South Africa came in the fourth ODI, when South Africa took advantage in a rain-shortened game to pull one back and make it 3-1. That kept the home team alive, only for India to snuff out its hopes of drawing the series with a clinical win at St. George's Park.
