The fourth day of the match at St George's Park proved tense and action-packed, during which the Proteas team completely dominated, forcing Australia to fight for survival with a score of 156/4 in the second innings (trailing by 170 runs) after having to agree to a follow-on.
Marco Jansen demonstrated his mastery, concluding the rout of the Australian team in the first innings. In addition to previously distinguishing himself with a wrist shot, scoring 85 runs, Jansen led the South African team's attack with the ball.
This left-arm fast bowler took 5/33 in Australia's first innings, dismantling the opposition's middle order through relentless pace and sharp bounce. In his morning session, he removed the dangerous Travis Head, and then before lunch, twice in three balls, dismissed the dangerous Matt Renshaw and Alex Carey.
Holding a huge advantage of 326 runs after Proteas finished destroying Australia's last four wickets for only 30 runs after lunch, Temba Bavuma insisted on a follow-on without hesitation. Kagiso Rabada marked the milestone by taking his 200th Test wicket on home soil in Australia's first innings when he dismissed Mitchell Starc. While Wiaan Mulder helped the team by taking two crucial wickets, including a major success against Steve Smith for 28 runs shortly after the former Australian captain surpassed 11,000 Test runs.
The day was not without losses for both teams. Proteas fast bowler Anrich Nortje felt pain in his groin in the fourth over of the morning session and could not continue bowling for the day, which was a serious blow to South Africa's workload management. Meanwhile, the Australian batting lineup was changed in the second innings as Steve Smith dropped down the order due to constant neck strain that prevented him from playing in his usual fourth position.
Australia faced difficulties at the start of the second innings when Rabada dismissed Nick Maddinson for 8 runs. However, Travis Head (87*) and Marnus Labuschagne (39) showed commendable resilience, building a solid partnership of 92 runs to slow down the Proteas. Head helped Australia resist throughout the day and evening, scoring a half-century in the struggle and counter-attacking under the darkening sky and strong wind.
Just when it seemed Australia was ready to bat all day, the South African bowlers delivered decisive blows before sunset. Off-spinner Simon Harmer broke up a dangerous partnership by dismissing Labuschagne, and later caught Bo Bubster on a legitimate delivery for 8 runs. Meanwhile, Rabada returned to bowl against Matt Renshaw, who scored 11 runs. When Australia approached 156/4, still trailing by 170 runs, and night watchman Scott Boland prepared to continue the game on Thursday morning with Head.
