83.55 - Rohit Sharma's Test average in India. Among the 203 batsmen who have scored at least 1500 runs at home - Sharma reached that milestone today - only one batsman, Don Bradman, has done better. Sharma has seven hundreds in 23 innings in India, of which four have been 150-plus scores. Only once has he been dismissed for less than 150 after he has passed 100.
19 - Hundreds for Sharma in international cricket since the beginning of 2018, the most among all batsmen. Virat Kohli (18) and Joe Root (13) are next in the list. Sharma has struck four hundreds in Tests, 13 in ODIs and two in T20Is; no other batsman has struck multiple hundreds in each format in this period.
162 - The partnership between Sharma and Ajinkya Rahane. Only once has India's fourth-wicket pair added more runs at home against England: Mohinder Amarnath and Mohammad Azharuddin put together 190, also in Chennai, in 1985.
7 - Test hundreds at home for Sharma, without a single overseas century. Among all batsmen without an away hundred, only one - Mominul Haque - has more centuries at home (10). Only two other batsmen have scored their first away hundred after making more than seven centuries at home: Allan Lamb (nine) and Mahela Jayawardene (eight). Robin Smith had seven centuries in England before scoring his first one away from home.
31 - Runs scored off the sweep shot by Sharma - he played the sweep 16 times during his 161. In all, India scored 39 runs off that shot on the first day of the second Test, and attempted the shot 26 times. In the first Test, they attempted the sweep shot only five times, and scored 10 runs.
4 - Ducks for Kohli in home Tests, all of which have come in his last 21 innings - his first duck at home was in the 2017 Test against Australia, which India lost. In these 21 innings, though, Kohli averages 76.44, with six centuries; in his previous 42 innings in India, Kohli didn't score a single duck, and averaged 61.21.
0 - Extras conceded by England in India's innings so far, which is currently the second-highest innings score without any extras in Test history. The highest completed innings without an extra is 328 - India bowled 187.5 overs in that innings against Pakistan, in Lahore in 1955, without conceding a single extra.
