India suffered a spectacular collapse, losing six batters for no run as 23 wickets fell on a crazy opening day of the second Test against South Africa at Newlands on Wednesday. Earlier, South Africa was bowled out for just 55 in 23.2 overs, sliding to its lowest total since being readmitted to Test cricket in 1991, after Mohammed Siraj claimed a test-best haul of 6-15. South Africa then reached the close of play on 62-3 in its second innings, trailing by 36 runs overall, with Aiden Markram unbeaten on 36 and David Bedingham seven not out.
