Tall, explosive and highly competitive, Marsh made great strides in his early years at the Holden Centre. Recruited as a mercurial half forward, he was quickly moulded into a reliable key defender who used his closing speed and long reach to great effect. It was outstanding VFL form in this position that saw Marsh make his debut in late 2015, a tally to which he added a further 10 games in the second half of 2016.
