Smith, 223 not out overnight, was finally out for 232 when Abdur Razzak bowled him around his legs sweeping in the 95th over of the innings. By then the duo had surpassed Indian pairing Vinoo Mankad and Pankaj Roy’s 413 that was made against New Zealand at Chennai in 1956.  

Smith was not merely playing for records and did his best to maintain a positive approach throughout his innings, which spanned 277 deliveries and included 33 fours and a six. 

McKenzie, 169 overnight, registered his maiden Test double century before he was dismissed for 226. His innings was more watchful as he required a further 112 minutes and 11 balls than Smith to make his runs.

After Jacques Kallis failed to build on the momentum and laboured to 39 not out off 120 balls, Smith declared on 583-7.

Fast bowler Dale Steyn then helped reduce the home team to 60-3 by stumps – taking all three - and reached 100 Test wickets. All three were caught and the third (his 101st) was that of Bangladesh’s best batsman and skipper Mohammad Ashraful.

Steyn, in his 20th Test match, became the fastest South African bowler to reach 100 Test wickets – two better than off-spinner Hugh Tayfield.

South Africa are leading 1-0 in the two-match series and look set to make that 2-0 unless Bangladesh can reverse the current momentum or the weather intervenes.
