PORT ELIZABETH - Dale Steyn and Rory Kleinveldt ripped out New Zealand's top order batsmen as South Africa took control on the second day of the second and final Test at St George's Park on Saturday.
New Zealand were reeling at 6-47 at the close, a massive 478 behind South Africa's first innings total of 8-525 declared, needing another 279 to avoid the follow on.
There were three centurions in the South African innings, with Faf du Plessis (137) and Dean Elgar (103 not out) joining first day hero Hashim Amla, who added only four to his overnight score before being dismissed for 110.
Steyn, bowling his fastest spell of the summer, had Martin Guptill (1) and Kane Williamson (4) caught in the slips in his first three overs.
Then the strongly-built Kleinveldt produced a snorter of a delivery to have Dean Brownlie (10) caught behind off his gloves.
