The first new face through the door in St Kilda's 2025 trade period, Silvagni arrived after 128 games for Carlton, where he was a third-generation player at the club. A groin injury cut short what was shaping as a career-best 2025 in defence, and the 194cm high-flyer now partners Callum Wilkie in the Saints' back half. He has played 151 AFL games and kicked 94 goals.
