Cape Town - Pace for Piedt as Proteas seek perfect balance?

If he scores just six runs in the second Test, Du Plessis will become only the third South African to score 2 000 runs as a Test captain.
Graeme Smith comfortably leads that statistic with 8 647 runs while Test skipper with Hansie Cronje second on the list with 2 833.
Du Plessis, who scored 55 and 13 in the first Test match, will captain South Africa for the 31st time in Test cricket on Thursday.
