All-rounder Wiaan Mulder took three wickets in quick succession to put South Africa on top on the second day of the second Test against Bangladesh at St George’s Park here on Saturday. Bangladesh were 139-5 at the close in reply to South Africa’s first innings total of 453. 

Bangladesh lost a wicket in the first over of their reply when first Test century-maker Mahmudul Hasan was caught at first slip off Duanne Olivier for nought. Tamim Iqbal and Najmul Hossain put on 79 for the second wicket, scoring at nearly four runs an over, before the medium-paced Mulder came into the attack.
