David Warner and Marnus Labuschagne hit centuries to set up a 123-run win for Australia in the second ODI against South Africa in Bloemfontein on Saturday.
Warner made 106 and Labuschagne 124 in an Australian total of 392-8 after the tourists were sent in.
Leg-spinner Adam Zampa took 4-48 as the Proteas were bowled out for 269 in the 42nd over.
Quinton de Kock (45) and captain Temba Bavuma (46) put on 81 in nine overs to get South Africa off to a quick start before De Kock was caught and bowled by Nathan Ellis.
Zampa struck twice in successive overs to dismiss Bavuma and Aiden Markram and the Proteas were unable to mount a serious challenge, although Heinrich Klaasen and David Miller both made 49.
“Our intent and execution tonight was as good as it gets,” said Australia captain Mitchell Marsh.
HIGHLIGHTS: Proteas vs Australia (2nd ODI)
Warner and Travis Head dominated the Proteas’ fast bowlers during an opening partnership of 109 off 72 balls, with Head thrashing 64 off 36 balls with nine fours and three sixes.
There was a brief respite for South Africa when left-arm wrist spinner Tabraiz Shamsi dismissed Head and Marsh off successive deliveries.
But Labuschagne followed up his match-winning 80* in the first match at the same venue on Thursday – when he came into the team as a concussion substitute for Cameron Green – with another Man of the Match performance.
Warner and Labuschagne put on 151 for the third wicket off 124 balls, with Warner going to his 20th ODI century off 85 deliveries.
Labuschagne was even quicker, reaching his second ODI century off 80 balls.
Both his hundreds have been made in the country of his birth. He hit 108 in Potchefstroom in March 2020.
“The boys at the top got us off to a lightning start and put pressure on the bowlers,” said Labuschagne, who said the fact that he had not been selected for the World Cup was “not in my control – I am concentrating on enjoying my cricket and playing as well as I can.”
It was Australia’s third-highest total in the 50-overs format and the fourth-highest conceded by South Africa.
“They were on top of us from ball one,” admitted Bavuma.
