South Africa has secured its third straight victory over Australia to win the ODI series 3-2 and enjoy an edge over its rival ahead of the Cricket World Cup next month.

Australia captain Mitch Marsh hit 71 with six fours and six sixes, and Marnus Labuschagne struck a slower 44, in reply but the innings was undone by left-armer Jansen who claimed the top five batters for his first ODI five-for.

The defeat left the tourists lamenting the loss of early wickets – in this match and earlier games.

“We can’t afford to expose our lower-order hitters at six and seven, where we do have some power down there, too early,” coach Andrew McDonald said. “That happened a bit too often in this series.”
