[1] Kerridge made his AFL debut in Round 3, 2012, against Hawthorn, starting as the substitute, and did not play another game in a successful year for the side.

In 2013, Kerridge played 11 games and established himself as one of Adelaide's main taggers, nullifying the impact of key opposition players including Chris Judd, Ryan Griffen and Grant Birchall.

[2] He also showed promise as an offensive player, most notable against North Melbourne in round 9 where he helped the Crows claim a thrilling come from behind win with 6 goals and 24 disposals, for which he was awarded an AFL Rising Star nomination.

He continued to rotate between tagging duties (in the absence of regular tagger Nathan van Berlo) and an opportunist small forward role.

[5] He immediately found a regular place in the Carlton midfield, playing all but one game for the season and finishing tenth in the best and fairest.
