Mohammed Siraj produced a spell to remember as India bundled out South Africa for 55, their lowest total against the visitors, inside lunch on day one of the second Test here on Wednesday. In a straight spell of nine overs, Siraj picked a career-best 6 for 15 as the South African batters made a beeline back to the dug-out, unable to counter the disconcerting bounce and the movement, both inward and outward, that he extracted off the surface.It was also South Africa's lowest total in Test cricket since their readmission into international cricket in 1991.
