A career-best century by Aiden Markram added pain to an Australian side reeling from the ball tampering scandal on the first day of the fourth and final Test against Australia at the Wanderers Stadium yesterday. Markram made a flawless 152 before the beleaguered Australians fought back with four late strikes as South Africa finished on 313 for six on the best batting pitch of a series which SA lead 2-1.
