Steve Smith, speaking to Fox Cricket before play, noted the pitch looked greener than a couple of days ago and said it could be tricky for the batters early doors. He also remarked on the groundsman's unusual approach to not using hessian covers on the pitch to retain moisture. The covers were briefly back on the square before play, threatening a delay, but were later removed.
Australia retained the same batting order from their first Test win in Durban, with Travis Head and Nic Maddinson opening, Matt Renshaw at No.5, and Beau Webster keeping his place. The XI: Travis Head, Nic Maddinson, Marnus Labuschagne, Steve Smith, Matthew Renshaw, Alex Carey, Beau Webster, Pat Cummins (c), Mitchell Starc, Scott Boland, Josh Hazlewood.
South Africa's XI: Aiden Markram, Marques Ackerman, David Bedingham, Temba Bavuma (c), Matthew Breetzke, Ryan Rickelton, Wiaan Mulder, Marco Jansen, Simon Harmer, Kagiso Rabada, Anrich Nortje.
According to reporter Daniel Brettig, about 10 minutes before the toss, Lyon had a brief chat with selection chair George Bailey and then walked over to give a handshake hug to Boland, who had been warming up with the other quicks. Lyon has been omitted from pink-ball Tests occasionally but had not been left out of a red-ball Test since the 2013 Ashes.
