Root, who had reached within striking distance of Marnus Labuschagne after the first Test, has wrested back the top spot from the Australia batter, whom he now leads by five rating points. Root is on 897 points after his knock of 176 in the first innings of the Nottingham Test, 20 less than his highest of 917 points, according to ICC.

Root first grabbed the number one position in August 2015 and was last at the top in December 2021 before Labuschagne leapfrogged him. Root has been No.1 in Tests for 163 days so far. Steve Smith (1,506 days), Virat Kohli (469 days) and Kane Williamson (245 days) are the others to have had substantial vigils at the top in recent years.
Root's compatriots, Player of the Match Jonny Bairstow and captain Ben Stokes have also had major gains. Bairstow's 92-ball 136 that led the last day chase for an eventual five-wicket win, has moved up 13 places to 39th position while Stokes`s 75 not out has taken him from 27th to 22nd position.
Ollie Pope (up 22 places to 53rd) and Alex Lees (up 26 places to 86th) have also moved up the rankings for batters while seam bowler Matthew Potts has advanced 18 places to 59th after picking up three wickets in the match.
