It was announced today that Brook would be in charge for that series, with Jos Buttler remaining sidelined with the calf injury that has kept him out of action since the end of June.

Brook’s promotion, after just 15 50-over appearances and less than a year on from admitting he was “still trying to figure out the format” during England’s dire World Cup defence in India, continues England’s recent policy of blooding a new generation of leaders.

Ollie Pope stepped in for Ben Stokes during the recent Test series and Phil Salt deputised for Buttler during the T20s.

Brook, a former England Under-19 captain who acted as Northern Superchargers skipper during this year’s Hundred tournament, was eager to throw himself into the role — seeking out caretaker coach Marcus Trescothick within minutes of the washout being confirmed.

“We’ve already discussed a few things in previous messages or in conversation. We’ve got a very good relationship already so we’ll carry that on,” Trescothick said.

“We’ve seen Brooky do a little bit in the Hundred this year with Superchargers and it’s a chance to expose him to his environment, have him leading the group.”
