Jansen Leads South Africa's Charge as Australia Are Bowled Out for 99

Australia's batting folded on day four of the second Test. The Baggy Greens were bowled out for just 99, and South Africa enforced the follow-on, meaning the touring side must bat again straight away. It is a stark turnaround for a team that had been looking to take control of the match, and it leaves South Africa with a real chance at a commanding victory.

Marco Jansen was the centerpiece of the collapse. His performance kept the pressure on Australia's order at the moments that mattered most, and it gave the home side the momentum to push the match in their favour. For a bowler who has often been the unsung member of South Africa's attack, it was a performance that will be talked about for some time.

The follow-on is a significant tactical move. By asking Australia to bat again immediately, South Africa have put the Test in their own hands, with the aim of setting up a victory rather than simply saving the match. The size of the win will depend on how much time remains and how the Australian batters respond in their second innings, since a quick second dismissal would make the margin decisive.

South Africa's comeback has been a long time coming in this Test. Having been second best earlier in the contest, they have now turned the momentum in their favour. Australia will need a defiant effort with the bat to stop the rot, and the next session will be a major test of their resilience.
