England vs South Africa 2017: 5 players who disappointed for South Africa in the Test series

#4. Quinton de Kock

The keeper batsman will have to improve a lot

Tipped to be the future of South African cricket, De Kock’s performances with the bat were quite inconsistent this series. The 25-year old scored 185 runs from 8 innings at an average of only 23.13 and if you take out his two fifties from the equation, then he averages only 11 from 6 innings.

Judging from his performances, De Kock has not been able to build up a long innings and spend more time in the middle. Coming in at No.4, his responsibility is to stay on the crease for a while and build up long partnerships with other middle-order batsmen. However, he failed to fulfil the expectations.
