Yet it's the Australians who are in disarray.
The final game of the series which will also be a day-night encounter will be played between 24th and 28th November.
It was a body blow for the Australian hopes of salvaging the Test so early into the fourth day and ended a 50-run stand with Smith.
The Australians were finished off before lunch on the fourth day - which was effectively the third, given Sunday's wash-out - to lose by an innings and 80 runs.
The Australian squad members had no red ball cricket in between the disaster that was the tour of Sri Lanka to the first Test in Perth.
"That is the mission for us now", he said. "We won't just rest on our laurels". "This cricket team is a tough team to get a win against on their home soil", said Faf du Plessis, the South African captain. "It's hard enough to get them in this position so we will do everything we can to make it 3-0".
The pace trio of Vernon Philander, Kyle Abbott and Kagiso Rabada were each phenomenal in their respective bowling spells in the second test, as they clawed hastily away at the Aussie batting attack for the Proteas' single total to be enough to win by an innings.
Smith is now top-ranked batsmen in the world, with 15 centuries to his name in 45 Tests, but his role as a captain has been under the scanner following five successive Test defeats that also saw Australia slip to third from first in the team rankings.
De Kock has scored 540 runs in 2016 in just nine Test innings and leads the year's worldwide averages with 80 having been unbeaten twice.

It was all over in 19.2 overs on day four. The coach said only four players from the team that played in Hobart are assured of a spot for the Adelaide Test.
We have to find a way to be a bit more resilient.
"To come here and do it 2-0, is special for us as a team ..." The confidence from coming over five-nil has helped us a lot and I think it will be the same case going into that last Test match.
"We need to find a way to have a bit more fight and hunger, and a bit more pride".
Tainted though that result was there was no doubting that England were the better team in the Test series that followed in South Africa.
"It's definitely attitude. It's an aggressive attitude that makes sure you're always in the opposition's faces, " du Plessis explained of South Africa's approach to the series.
Former openers Simon Katich and Chris Rogers have led a stunning assault on Australia's insipid Test side, saying up to six players should be axed following the Hobart debacle.
Du Plessis added: "We are a team that's confident at the moment, so we use that and we walk and talk that on the field, our body language is extremely good".
