Matt Renshaw continued to hog centre stage as Australia pushed closer to winning the first Test against South Africa in Durban.
Renshaw added a second-innings knock of 82 to his game-shaping 190 and was not finished there. After Australia declared with a lead of 420, the occasional off-spinner picked up his maiden Test wicket as the Proteas laboured to 102-4.
South Africa captain Temba Bavuma was his victim, caught off bat and pad by Nic Maddinson for just one. Josh Hazlewood had already got the ball rolling, dismissing Ryan Rickelton and David Bedingham, with Pat Cummins adding Tristan Stubbs before the close on day four.

Aiden Markram will resume on 45 not out alongside Wiaan Mulder but the odds are stacked against the hosts salvaging the game on day five. Australia were without Steve Smith's brilliance at slip after he was hit on the helmet by Anrich Nortje and was subsequently replaced in the field pending further assessments.
