He was called up for his second game in Round 11, 2019. Clarke lined up on Carlton captain and Brownlow Medal favorite Patrick Cripps, and kept him to the quietest game of his entire career, as one of the best players on the ground.
He played in Essendon's next game in Round 13 against Hawthorn, once more playing a tagging role, holding Hawthorn star Jager O'Meara to 14 disposals to three quarter time and 23 for the match, while gathering 23 possessions himself. He was again one of the best players on the ground, and was recognized with the NAB Rising Star nomination for round 13.
Clarke was delisted by the Bombers at the end of 2021.[4]
