Irish born O’Connor comes from a Gaelic football background where he played with County Kerry. Mark’s impressive skills and AFL potential saw him find his way onto the AFL radar. After attending the International Combine, O’Connor showed his athletic traits at the 2016 NAB AFL Draft Combine, running a 9.56 3km. The 189 centimetre prospect was sought after, with three AFL clubs chasing his signature. Geelong prevailed and signed O’Connor as a Category B Rookie. O’Connor joins Geelong as the second Irish-born athlete alongside Zach Tuohy.
In early 2017, O’Connor was upgraded to Geelong’s senior list. Mark’s form in the VFL was highly promising as he displayed great improvement in his newly adopted game. His running in through the midfield as well as disposal was a large factor of his elevation. Mark debuted for the AFL side against Essendon. After finishing the year with 2 senior appearances, Mark’s progress has been excellent and he will now look towards the 2018 season where he hopes to make further contributions.
