2) Hendricks/ Bavuma
3) Bavuma/ Hendricks
What we know is that the wickets are slow and favour the batsman, the above team has batting depth to 10 with the inclusion of Hendricks and Phulehkwayo. Markram and Phulehkwayo share 10 overs which adds flexibility and variety with spin and slow bowling through 10 overs. Shamsi has yet to prove himself at the highest level and you'd have to ask whether it's worthwhile taking the risk in a knockout semi. With the out of form Bavuma, Hendricks and Phulekwayo hopefully provide the necessary batting cover. Phulehkwayo if he keeps it tight could be a healthy weapon as a slow bowler on wickets that do not favour pace bowling.
Luck is an important part of winning the Proteas are going to need some go their way, winning the toss would be a great start.
