South Africa have secured a one-day international series win against Zimbabwe thanks to a 61-run victory in Bulawayo.

Having won the first of three encounters between the teams last week, the Proteas moved into an unassailable 2-0 lead on Tuesday with a dominating display.

The tourists were made to bat first and were bowled out for 257 before reducing Zimbabwe to 196.

Faf du Plessis top-scored for the visitors with a knock of 55, while Quinton de Kock (38), JP Duminy (36) and David Miller (45) also made significant contributions at the crease.

Sean Williams's valiant score of 55 helped Zimbabwe put up a modest fight when it was their turn out in the middle, but Neville Madziva (25) and Brian Vitori (20) were the only other batsmen to make 20 runs or more.

Wayne Parnell and Ryan McLaren did most of the damage with the ball for South Africa, taking three wickets apiece by the end.

The teams play their third and final ODI on Thursday when they meet again in Bulawayo.
