Dale Steyn and his fellow fast bowlers enabled South Africa to gain an advantage over Sri Lanka on the second day of the first Test against Sri Lanka at Kingsmead in Durban on Thursday.

Steyn took four for 48 as South Africa took a first innings lead of 44. They stretched their lead to 170 by reaching 126 for four at the close. South Africa's decision to pick five specialist bowlers meant that their advantage was some way short of being decisive, with Faf du Plessis (25 not out) and Quinton de Kock (15 not out) their last two recognised batsmen going into day three.
