JOHANNESBURG (AFP) - Dale Steyn sent Pakistan crashing to a new low as South Africa took control on the second day of the first Test at the Wanderers Stadium on Saturday.

Steyn took six for eight in 8.1 overs as Pakistan were shot out for 49, four fewer than their previous lowest total of 53 against Australia in Sharjah in 2002-03.

South Africa led by 204 runs on the first innings but decided not to enforce the follow on. The hosts were 73 for no wicket in their second innings at tea, an overall lead of 277.
