The South African cricketers have defeated Australia by six wickets in the final of the triangular series in Harare, Zimbabwe.
After losing the toss and being sent in to bat, Australia found the going difficult, slipping to 7-137 before some late resistance got the end total to 217 for 9.
Aaron Finch top scored with 54, while James Faulkner made a handy 39 late in the innings.
In response, South Africa set a good tempo in a calculated chase, steered by Hashim Amla (51) and the dominant batsman of the tournament, Faf Du Plessis, who top scored with 96 as the Proteas passed the total for the loss of four wickets and nine overs and two balls to spare. AB de Villiers also made 53 not out.
Dale Steyn picked up man of the match, while Faf Du Plessis was named man of the series.
Meanwhile, Steyn has revealed he may never forgive Michael Clarke for a personal sledge made by the Australian skipper during the Cape Town Test earlier this year.
Lifting the lid on the lingering bad blood between the pair ahead of South Africa's tour of Australia in November, Steyn intimated he's never been more deeply offended by a comment on the cricket field than by what Clarke said to him in the final session of a bitter series won by Australia back in March.
Clarke claims he spoke to Steyn immediately after the match and also said sorry for overstepping the mark at a post-match press conference.
But Steyn clearly hasn't accepted Clarke's remorse as genuine.
The Australian skipper intervened while Steyn was having words with James Pattinson, prompting the Proteas star to blow up in response - although the exact nature of Clarke's sledge is unknown.
Clarke claimed when leaving Harare with injury before the end of the triangular series that he believed he had set the record straight with Steyn.
But Steyn still holds a grudge, stating "the day (Clarke) comes and shakes my hand and says 'I really mean what I said' and behaves like the way he should, maybe then I will (forgive him).
