India's biggest win, and SA's 143-over crawl
337 India's margin of victory, their biggest in terms of runs in Test history, beating their 320-run win against Australia in Mohali in 2008-09. It was also the second-biggest Test defeat for South Africa in terms of runs, next only to their 530-run loss against Australia in Melbourne in 1910-11.
2006 The last time South Africa lost three or more matches in a Test series, when they were whitewashed 3-0 by Australia at home. Since their readmission, this is only the third time they have lost more than two matches in a Test series.
5 Number of Man-of-the-Series awards for R Ashwin in his Test career. Since his debut, India have won six Test series and in five of those Ashwin won the award. He also equals the record for most such awards among India players, along with Sachin Tendulkar and Virender Sehwag. Also, Ashwin's five series awards are the most by any player since his debut, one more than AB de Villiers.
143.1 Overs played by South Africa, the most by any team in the fourth innings of a Test in Asia. South Africa bettered Bangladesh's 142 overs against Zimbabwe in Dhaka in 2004-05. Overall, this is the fourth-longest South Africa has batted in the fourth innings of a Test.
0.99 South Africa's run rate in the fourth innings: they scored 143 runs in 143.1 overs, which is the lowest for a team batting 100 or more overs. This is the only time a team has scored at less than one run per over after batting 100 or more overs. The highest strike rate by a batsman in this innings was 33.33, by Morne Morkel.
2.10 Runs per over in this whole Test , which is the lowest in a Test in India since 1991, for a minimum of 90 overs played. Overall, there have been seven Tests in India with an overall run rate of less than two.
31 Wickets taken by Ashwin in this series, the fifth-highest in a series by a bowler who has bowled in seven or fewer innings, and second-highest by an Indian after Harbhajan Singh's 32 wickets in the Border-Gavaskar Trophy in 2000-01.
7 Five-wicket hauls for Ashwin in Tests in 2015, the most by an India bowler in a calendar year. Subhash Gupte in 1955, Harbhajan Singh in 2001 and Anil Kumble in 2004 took six five-wickets hauls in a calendar year. Ashwin is the leading wicket-taker this year in Tests with 62. If no other bowler goes past this mark, he will be first Indian since Anil Kumble in 2004 (74 wickets) to be the highest wicket-taker in Tests in a calendar year.
17 Consecutive maiden overs delivered by Ravindra Jadeja in the fourth innings, from his 20th over to his 36th over. Jadeja missed Bapu Nadkarni's record for the most consecutive maiden overs: Nadkarni bowled 21 maidens in a row against England in Chennai. Jadeja's 108 consecutive balls without conceding any run is the third-highest in a Test after Hugh Tayfield (137 balls across two innings) in Durban, and Bapu Nadkarni (131 balls) in Chennai.
0.56 Jadeja's economy rate in this innings, the best by any bowler bowling 35 or more overs. He bowled 46 overs conceding 26 runs. His economy rate is the second-best for all innings where a bowler delivered 25 or more overs.
0.42 Umesh Yadav's economy rate in South Africa's second innings, the best for a fast bowler with a minimum of 90 balls (15 overs). It is the third best among all type of bowlers, with a minimum of 120 balls (20 overs) bowled. His economy rate of 1.24 in this match is the best for him in his 17-match Test career. Before this match, his career economy was 4.26 which was the worst for any fast bowler who bowled at least 250 overs. His career economy rate has come down to 4.05 after this Test.
297 Balls faced by de Villiers in making 43 runs - the most in an innings of less than 50 runs ( in matches where balls-faced data is available). He missed out on breaking the record for the slowest half-century in Test cricket history - 350 balls by Trevor Bailey against Australia in Melbourne in 1957-58. This was the third time de Villiers played more than 200 balls without scoring 50: he also scored 33 off 220 balls in Adelaide in 2012-13, and 43 off 228 balls in Cape Town in 2014-15. In matches where balls-faced data is available, he is only the second player after John Wright to have play three innings of 200-plus balls without scoring 50. In terms of minutes batted, he is the only player to play over 300 minutes without scoring a 50 on two occasions.
