168* - Joe Root's score at the end of the second day in Galle. It is the highest by an England batsman in Sri Lanka, going past Kevin Pietersen's 151 in Colombo in 2012. There are only three instances of an overseas captain scoring more runs in an innings in Sri Lanka: Stephen Fleming's unbeaten knocks of 274 and 174, and Mushfiqur Rahim's 200.
2 - Test hundreds for Root in Sri Lanka, making him the first England batsman to score more than one Test century in the country. Eleven England batsmen have a solitary hundred here.
173 - The partnership between Root and Dan Lawrence, who made 73 on debut. It is England's highest stand for any wicket in Sri Lanka, going past the Nasser Hussain-Graham Thorpe partnership of 167 for the third wicket in Kandy 20 years ago. It is also sixth-best for the fourth wicket by an overseas team in Sri Lanka.
52.53 - Root's average in Asia: he has scored 1366 runs in 15 Tests, with three hundreds. He is one of only three England batsmen to score more than 1000 runs at a 50-plus average in Asia; the other two are David Gower and Alastair Cook.
5 - Non-Asian batsmen who average more than 50 in Asia since 2010, with a 1000-run cut-off. Neither Steven Smith (1200 runs at 48) nor Kane Williamson (1545 runs at 46.81) are in this club.
73 - Lawrence's score in his debut innings, which is exactly what Root scored on his Test debut in Nagpur eight years ago. In the last 69 years, only five England batsmen have made more runs when making their Test debut in Asia: Keaton Jennings (112 in Mumbai), Ben Foakes (107 in Galle), Cook (104* in Nagpur), Owais Shah (88 in Mumbai) and Haseeb Hameed (82 in Rajkot).
