Heinrich Klaasen produced another impressive batting performance as South Africa won the final one-day international against Australia by six wickets on Saturday, with 27 balls remaining, for a 3-0 series sweep.

Klaasen's 68 not out — to go with a century and another half century in the series — led South Africa to a comfortable victory despite Marnus Labuschagne's 108 for Australia against his country of birth.

Labuschagne was the anchor but Australia only managed 254-7 in its 50 overs at Senwes Park in Potchefstroom after being put in to bat. Labuschagne's century came about 50 kilometers (31 miles) up the road from Klerksdorp, the city where he was born.
