6 - Consecutive Test wins for England in Sri Lanka, the second-best for them in any country. The streak started in 2012 when they levelled the two-Test series, continued in 2018-19 with a 3-0 sweep, and reached new heights with the two wins in Galle. Only once have they won more successive Tests in a country: in the period between 1889 and 1899, when South Africa started out as a Test-playing nation, England won eight in a row in that country. England's six in a row here is also the most by a non-Asian team in Asia, going past the five by them in Bangladesh, and the five by Australia in Sri Lanka between 2002 and 2011.
426 - Joe Root's aggregate in the series. Only once has an England batsman scored more runs in a series in which he played two or fewer matches: in 1932-33 tour to New Zealand, Wally Hammond scored 563 runs in just two innings, including an unbeaten 336 in Auckland.
44.4 - Percentage of England's runs off the bat scored by Root in the series: he made 426 out of the 980 runs scored by all the England batsmen. The percentage of 44.4 is the fifth-highest in the all-time list for any series of two or more Tests. On top is Hammond's 52.4%, in the series mentioned above.
6 - Instances of England successfully chasing down a fourth-innings target in Sri Lanka. No other non-Asian team has done it even once in Sri Lanka.
0 - Tosses that England won in the series. They lost the toss in both Tests and yet ended up winning the matches. What England achieved in successive Tests has been done only once previously by a visiting team in Galle, when Pakistan lost the toss but won the Test in 2000. The other seven wins by overseas teams in Galle have all happened after they won the toss.
5 - Tests won by England in Asia after losing the toss in the last 10 years (since January 2011); apart from the two wins in Galle, they also won in Colombo, Mumbai and Kolkata in 2012. During this period, all the other non-Asian teams have won only four Tests in the continent after losing the toss.
0 - Instances of fast bowlers taking all 10 wickets in an innings, and spinners doing the same in a team's other innings of the same Test. In this Galle Test, England's fast bowlers took all 10 in Sri Lanka's first innings, while Jack Leach, Dom Bess and Root took all 10 in the second. The closest any team has come to achieving this was Australia against Pakistan at Lord's in 2010: Australia's seamers took all 10 in the first innings, while Marcus North (6 for 55) and Steven Smith (3 for 51) took nine in Pakistan's second innings.
25 - Test wins for Root as captain, which is the second-best by any England captain. Only Michael Vaughan, with 26, has more. Vaughan had 26 wins in 51 Tests, compared with Root's 25 in 46.
9 - Defeats for Sri Lanka in their last 12 Tests. They have lost five to England, three to India, and one to New Zealand.
