Brook rose up the ranks in Yorkshire after hitting a century in one of the great games at Chelmsford. After being all out for 50 in their first innings, Yorkshire, which had Jonny Bairstow, Joe Root, Cheteshwar Pujara and Garry Balance in the side, were guided by then 19-year-old Brook who hit a scintillating 124 in the second innings. The side from North England went on to win that match beating the reigning County champions Essex.
Brook had a phenomenal T20 Blast in 2021, hitting 486 runs in 13 matches at an astonishing average of 69.42 and a strike rate of 149. This season got him the much needed recognition and he made his move towards the overseas leagues.
