Australia nears Test win after South Africa's poor batting

Australia moved closer to a series victory in the third Test in Cape Town as South Africa’s top order struggled on day three. South Africa reached 140-4 at the close, holding a narrow 40-run lead after gifting wickets through careless shots.

Openers Aiden Markram and David Bedingham fell to poor decision-making, with Bedingham dismissing for the second time in the match by pulling into the hands of a fielder. Captain Temba Bavuma also fell to a wild swipe, leaving the Proteas in a precarious position against the Australian bowling attack.
