2.03pm KK will step into commentary for the start of the innings.

Rajesh has given us the WTC permutations: If Aus draw here and lose all 4 in Ind they slip to 59.65. SA, with a draw here and a 2-0 verdict vs WI, go to 55.56. SL can go to 61.11 with a 2-0 series win in NZ. Ind will be on 68.06 if they beat Aus 4-0, 62.5 if they win 3-1, and 56.94 with a 2-2 verdict. So for SA to still be in with a chance, they need SL to not win 2-0, and Ind to get fewer than 24 points that they would with 2 wins. Even if Aus draw just one Test in Ind (if they lose 3-0) they will go up to 61.4, which is marginally more than SL's max (assuming a draw in Sydney and no docking of points). If SL win only 1-0 in NZ they finish on 55.56, which will be below Aus even if they lose 4-0 to Ind.

1.58pm Inning break Australia enforce the follow on. Australia need 10 wickets to win the game and South Africa have to survive 47 overs. Hazlewood brilliant after lunch to end the Maharaj and Harmer resistance. Hazlewood and Cummins take seven of the 10. Can they muster the energy to do it again. Lyon started to look more dangerous post lunch.

Rickp: "Hazelwood shows the way if you can't rely on catchers or umpires for lbw - hit the stumps. Gazza shows of you can't rely on catchers, do it yourself. "

Jo: "Such typical Hazlewood and Lyon, build pressure with a tight bowling partnership until someone cracks."
