Having dismissed India for 209 in the first innings, South Africa resumed on 65-2 with no play possible on day three, but quickly slumped to 130 all out, Mohammed Shami (3-28) and Jasprit Bumrah (3-39) the pick of their bowlers as India had the scent of victory in their nostrils.
The tourists' target of 208 soon seemed out of reach, however, as the Proteas blitzed through India's batting line-up, even without Steyn - whose comeback was curtailed by a heel injury.
