With nothing to lose, I would focus on making critical changes, particularly in the batting lineup. The top order is struggling, so this would be my revised team and order, excluding Bavuma and Markram. This is just my opinion on the order, and I have no issue with it being changed, but I would prefer to see the two players mentioned above replaced.
1 Breeztke
2 Da Sauce
3 Brevis
4 Pretorius
5 Rickelton
6 Mulder
7 Stubbs
8 Bosch
9 Burger
10 Ngidi
11 Maharaj/Muthusamy
