Australia are seemingly destined for another defeat after being dismissed for just 167 in the fourth one-day international against South Africa in Port Elizabeth.
The Proteas will now have to chase down 168 to take a 4-0 lead in the five-game series.
After winning the toss and opting to bat first, the tourists were immediately in trouble when Kyle Abbott (4-40) and Dwaine Pretorius (1-33) found some assistance off the St George's Park pitch with the new ball.
Aaron Finch (2), David Warner (6) and George Bailey (1) all fell in quick succession to leave Australia 3-12 inside four overs.
Abbott, playing in his first match of the series as the Proteas rested Dale Steyn, Kagiso Rabada and Imran Tahir, clean bowled Finch and Warner before Pretorius trapped Bailey LBW.
Tabraiz Shamsi (3-36), also playing his first match of the series, then struck twice in the same over to remove Steve Smith (21) and Travis Head (0) as Australia slumped to 5-49 after 15 overs.
Mitch Marsh (50) and Matthew Wade (52) combined in a half-century stand to lift Australia's total past 100 but when Proteas' captain Faf du Plessis recalled Abbott the end came swiftly.
Abbott removed Marsh and then clean bowled Adam Zampa either side of Shamsi making John Hasting his third LBW victim as Australia slumped once more to 8-121.
Chris Tremain (23no) shared a 46-run stand with Wade that included some lusty blows before Aaron Phangiso (2-17) wrapped up the innings with two wickets in four deliveries in the 37th over.
Australia have made one change from the team which lost game three at Kingsmead, with Scott Boland coming in for Dan Worrall.
As well as the rested bowlers, Durban match-winner David Miller (groin) is out for the South Africans through injury.
His spot is taken in the middle order by the recalled Farhaan Behardien.
