3. Reeza Hendricks
The experienced Reeza Hendricks would be another option for the South African team replacing AB de Villiers. He has just 12 T20Is for South Africa and scored 275 runs with the best score of 70. He has lots of experience of playing List A cricket with 4494 runs from 138 matches.
Reeza Hendricks lack of experience in ODI cricket could work against him but with ODI matches coming up this year, he could be selected in South African ODI team and if he could perform well then Reeza might be there in the World Cup squad.
