South Africa 162 (Hamza 62, Yadav 3-40, Jadeja 2-19) and 132 for 8 (De Bruyn 30, Shami 3-10, Yadav 2-35) trail India 497 for 9 dec by 203 runs

India need two wickets to complete a whitewash over South Africa but they will have to wait until Tuesday morning to do it. The visitors might have one more night in India, awaiting a fate that was writ from the second innings in Visakhapatnam, when Mohammed Shami ripped through their middle order and showed how much of a role seam bowlers would play in this series.

Though R Ashwin remains on top the wicket charts, it was Shami and Umesh Yadav who exposed a weakness South Africa would not have dreamed they had, especially not in the subcontinent.

South Africa have been surprised by short balls, beaten by pace and caught off guard by bowlers who attack the stumps, the very same thing they have seen their own attack do, season after season. But this is the season of change and India have spent the series showing how much they have evolved. No longer a team that relies on conditions loaded in the spinners' favour, they are now an outfit that wins away and that is not only happy to compete on fair-minded surfaces, but can dominate on them.
