6 England captains who have scored Test hundreds on captaincy debut, including each of the last four. Before Joe Root's unbeaten 184, Alastair Cook started his captaincy tenure with 173 against Bangladesh, while Kevin Pietersen scored 100 against South Africa, and Andrew Strauss made 128 against Pakistan, also at Lord's. The other England captains to achieve this feat are Allan Lamb (119 against West Indies in 1990), and Archie MacLaren (109 against Australia in 1897). Root's 184 not out is the highest among these six scores.
3 Batsmen who have made higher scores in their first Test as captain: Graham Dowling (239), Shivnarine Chanderpaul (203 not out), and Clem Hill (191). Root also joins Virat Kohli (115 and 141) and Steven Smith (133) among captains who have scored hundreds on captaincy debut. Kane Williamson, the other member of the fab four club, scored 91 in his first Test as captain (and followed with 113 in his second).
81.42 Root's Test average versus South Africa: in nine innings against them he has passed 50 five times, including two hundreds.
118 Runs that Root scored off Keshav Maharaj and Kagiso Rabada, off 126 balls. Eighteen of his 26 fours, as well as his only six, came against them. Against Vernon Philander, he scored only 12 off 30 balls.
17 Innings for Root to complete 1000 Test runs at Lord's, which makes him the fastest to the landmark among the nine batsmen who have made 1000-plus runs here. The previous fastest was Strauss' 19 innings. In these 17 innings, Root averages 69.26, and each of his three hundreds here have been 175-plus scores.
6 Instances of England putting together century stands for their fifth and sixth wickets in a Test innings. The previous such instance was in Barbados in 2009. The five earlier matches have all been drawn, though.
3 Century stands between Root and Ben Stokes, including two at Lord's: against New Zealand in 2015, the same pair came together at 30 for 4 and were separated at 191 for 5. Today, they came together at 76 for 4, and were separated at 190.
13 Wickets off no-balls for Morne Morkel in his Test career, including the dismissal of Ben Stokes today. He had also dismissed Root off a no-ball in Cape Town in 2016.
