321: India's second-biggest win by runs
4 Whitewashes inflicted by India in a series of three or more Tests. Before this 3-0 sweep, they had whitewashed Australia 4-0 in 2012-13 and a couple of 3-0 wins against England and Sri Lanka in 1992-93 respectively.
2004 New Zealand's last whitewash in a series of three or more Tests, in England. This clean sweep to India is their seventh in Tests and only their third since 1990.
321 India's margin of victory in Indore, their second-biggest in terms of runs. The biggest - by 337 runs* - came was against South Africa in Delhi last year. Also, this was New Zealand's second-biggest defeat in terms of runs.
3 Number of players to have won the Man-of-the-Series award in four consecutive Test series. Ashwin is the third to achieve this after Imran Khan and Malcolm Marshall. Ashwin's streak began in Sri Lanka last year. He has got the award in seven of the eight Test series that India have won since his debut and he already has the most such awards among India players. No player from any other team has got more than four such awards since Ashwin's debut.
13/140 Ashwin's figures in this match - his best match figures in Tests. His previous best was also against New Zealand - 12 for 85 in Hyderabad in 2012. His match figures are the second-best by any bowler against New Zealand. He now has three ten-wicket hauls against New Zealand. The 7 for 59 in the second innings in Indore is his best effort in an innings.
96.62 India's average runs per wicket in this Test - they scored 773 runs and lost eight wickets - is their second-best in any Test win while batting in both innings. The only Test with a better average was against Pakistan at Brabourne (Mumbai) in 1952-53.
2 Indians to have taken two ten-wicket hauls in a series - Harbhajan Singh against Australia in 2000-01 and Ashwin in this series. Incidentally, both managed to do so in a three-match series. Sydney Barnes is the only bowler to take three ten-fors in a three-match series. This was Ashwin's sixth ten-for in Tests, two less than the most by an India bowler - eight by Kumble.
4 Number of 12-wicket hauls for Ashwin, the joint second-most by any bowler. Only Muttiah Muralitharan has taken more such hauls (6) while Barnes, Fazal Mahmood and Rangana Herath have four such hauls. Anil Kumble (3) has the most among Indian bowlers.
27 Wickets by Ashwin in this series - the second-most by any Indian bowler in a three-match series, behind Harbhajan Singh's 32 wickets in the Border-Gavaskar Trophy in 2000-01. Ashwin's tally is also the second-most by any bowler in a three-match series against New Zealand. Waqar Younis had taken 29 scalps in a 1990-91 series.
33.75 Williamson's average in this series, which is his lowest in the last 13 Test series since October 2013. The only other series where he averaged less than 40 in the previous 12 series also came this year - 35.50 in the Trans-Tasman Trophy at home. He got out to Ashwin in all four of his innings in this series.
5 Half-centuries for Gautam Gambhir in his last seven first-class innings. Before scoring 50 in the second innings of this match, he had made scores of 77, 90, 59, 94 and 36 in the Duleep Trophy. This was his first fifty in Tests since scoring 60 against England at the Eden Gardens in December 2012.
