Dean Elgar and Quinton de Kock centuries helped South Africa fight back on Friday as the tourists reached 385 for eight in response to India’s mammoth first-innings score of 502. De Kock made 111 and put on a key 164-run stand with Elgar, who scored 160, to thwart the Indian bowling attack on day three of the first Test. At stumps, the Proteas still trail by 117 runs.
