Edgbaston-product Aaron poses a big threat to opposing teams as a genuine all-rounder, bowling quickly and aggressively while also possessing the ability to be a game-changer with bat in hand.
His talent blossomed early. Aged just 17, Aaron returned from an England U19s tour to Australia as leading run-scorer and then tasted his first first-team experience for the Bears in a one-dayer against Middlesex at Lord's in 2014.
Injuries have interrupted his development but last year he was a regular in Birmingham's side, taking vital wickets at key times and contributing some eye-catching cameos with the bat.
Always keen to be at the heart of the action, he went down in Birmingham Bears folklore last season for delivering a brilliant, steel-nerved death over at Northampton to close out victory against the Steelbacks.
