Key Players
Australia: Mitchell Starc
The experienced left-armer picked up just one wicket during Australia's opening match at the tournament. He sent India opener Ishan Kishan packing in the very first over of the match.

Early breakthroughs are going to be crucial for Australia in this match given South Africa's strong batting line-up and Starc will be hoping he can get some swing from the wicket and make inroads.

South Africa: Aiden Markram
The right-hander looked in superb touch when he smashed the fastest century in Men's Cricket World Cup history against Sri Lanka and is sure to be the prized wicket that the Aussies will be chasing.

Markram brought up his hundred with a huge six off Dilshan Madushanka, reaching the milestone off just 49 deliveries and beating the previous record held by Ireland’s Kevin O’Brien against England in 2011, by one delivery.

The South African No.4 is more than capable of adjusting his playing style to the different conditions that he comes across to. He will be keen for another big score. (ICC)
