1 - Better bowling figures by a spinner in the first innings of a Test in Centurion than R Ashwin's 4 for 113. Graeme Swann had picked 5 for 110 at the same ground in December 2009, the only figures better than Ashwin's. Apart from these two instances, no other spinner has managed more than two wickets in the first innings of a Centurion Test. Ashwin bowled 38.5 overs in this innings, the third-most by a spinner in the first innings in a Centurion Test. No other India bowler sent down more than 22 overs in the first innings of this Test.
2 - Four-wicket hauls for Ashwin in Tests outside Asia excluding the West Indies and Zimbabwe. The first, before this match, was 4 for 105 at the SCG in 2014-15. He is yet to take a five-wicket haul in the 11 Tests he has played in Australia, England and South Africa.
94 - Percentage of deliveries Ashwin pitched at good length - 219 out of 233. Only 14 of his 233 balls were at other lengths. Of those 219 deliveries, 81 were outside the off stump and that's were all his four wickets came from. He pitched 119 good-length balls on the stumps. Thus, 200 out of his 233 deliveries (85.83%) were pitched at good length and landed either on the stumps or just outside the off stump.
543 - South Africa's average score in Centurion in the last five instances when they have batted first. They had scored over 400 on each of the five instances and weren't dismissed by the oppositions in two of those. Theirs scores were 418, 409, 552 for 5 decl, 475, 481 for 8 decl. However, they put together only 335 this time. They had at least one centurion in each of the last five times they batted first at the venue, but not this time.
100 - Wickets for Mohammed Shami in Tests. He became only the seventh India fast bowler to take 100 or more Test wickets. He got there in his 29th Test, which is the third-quickest among the seven after Kapil Dev (25 Tests) and Irfan Pathan (28).
1912 - The last time South Africa opened the bowling with a spinner in their first innings, which was by Aubrey Faulkner against Australia at Old Trafford. Keshav Maharaj became the first since then and only their third overall. George Rowe had opened twice in the first innings in 1896 and 1902.
