Wicket on first ball, then Yansen wreaked havoc

On the morning of the fourth day, Marco Yansen gave a big blow to Australia by dismissing Scott Boland on the very first ball. After this he also sent Travis Head to the pavilion. Marnus Labuschagne was trying to stay at the crease, but Simon Harmer took a brilliant catch diving to the left of gully and ended his innings.

Steve Smith and Matt Renshaw saved the wickets for some time. Both the batsmen were trying to handle the team till lunch, but Yansen increased Australia's problems by dismissing Renshaw and Alex Carey in the same over.

Australia's innings could not last long in the second session. Yansen completed his five wickets by dismissing Beau Webster. After this, Viaan Mulder ended Steve Smith's innings. Kagiso Rabada ended Australia's innings by dismissing Pat Cummins. The entire team was all out for 99 runs in 38.3 overs.

Head and Labuschagne took over the innings after follow on

After getting a big lead in the first innings, South African captain Temba Bavuma decided to give follow-on to Australia.

In the second innings, Rabada gave a great start to the host team by dismissing Nick Maddinson early.

After this Head and Labuschagne took over the responsibility. Both of them batted for about 30 overs and added 92 runs for the third wicket. Australia got some relief from this partnership and it seemed that this time the team will not repeat the same mistake as in the first innings.

Labuschagne once got the benefit of review in the decision of LBW, but after some time he tried to play a big shot against Simon Harmer and lost his wicket.

Marco Yansen took a brilliant catch while running backwards. In this way, he showed his impact in fielding along with bowling.

Rabada and Harmer again increased Australia's problems

After Labuschagne was out, Matt Renshaw tried to support Head, but Rabada dismissed him. After this, Head maintained the pace of scoring runs, but from the other end he continued to face the blow of falling wickets.

Beau Webster also could not last long. Harmer gave South Africa its fourth success by getting him out LBW.

After this, Australia did not lose any more wickets till the end of the day's play, but the team is still under great pressure.

Australia's hopes rest on Travis Head

Travis Head batted brilliantly in difficult conditions and completed his half-century. By the end of the day's play, he had scored unbeaten 87 runs on 138 balls. Scott Boland was present with him at the crease.

Australia's score in the second innings is 156 runs for 4 wickets and the team is still 170 runs behind South Africa. On the fifth day, Head will not only have to take his innings forward, but will also need cooperation from the other batsmen. On the other hand, the bowlers of the Proteas team will try to win the match by taking the remaining wickets as soon as possible.
