At the
2021 AFL draft on 25 November 2021, St Kilda matched a bid by with draft points for Owens and ultimately took him with pick 33 overall. Owens made his AFL debut in Round 1, 2022, against , collecting six disposals and two tackles. He was dropped back to the
VFL following his debut game. Owens earned a recall to the senior team in Round 11 against and put in an impressive display with 14 disposals, 10 tackles and 2 goals; however, in the following game, against Brisbane, a concussion forced him to sit on the sidelines for several weeks. He returned to the side in Round 20 against and played the final four games of the season.
2023 Owens was selected in the senior team in Round 1 of the 2023 season and quickly established himself as a core member of newly appointed coach
Ross Lyon's best 22 in the absence of regular key forwards
Max King and
Tim Membrey, playing predominantly forward with stints in the midfield and deputising in the ruck. Owens was nominated for the
AFL Rising Star in Round 4 against
Gold Coast Suns after a 27-disposal, 2-goal game. In Round 10, Owens was substituted out in the second quarter as the result of a concussion in which his head collided with teammate
Anthony Caminiti's knee, and subsequently missed the following match under the concussion protocols. Owens was recalled for the next match in Round 13 after St Kilda's bye, playing every match from then on to qualify the Saints for the finals in 6th place and an elimination final, including 4 goals against
West Coast Eagles. Throughout the backend of the season, Owens was considered to be one of three favourites for the
2023 AFL Rising Star alongside
Harry Sheezel and
Will Ashcroft, eventually finishing third with 33 votes behind Sheezel (winner, 54) and Ashcroft (second, 39), receiving maximum votes from
Nathan Buckley and at least 2 votes from every judge on the panel. Owens capped off his season by finishing fourth in the
Trevor Barker Award, receiving the Saints' Best Emerging Player award alongside teammate
Nasiah Wanganeen-Milera, and being named in the
22 Under 22 team, also alongside Wanganeen-Milera. Following a breakout year in 2023, Owens' role shifted at St Kilda. While matching his previous-best 23 appearances in 2023, his influence in
2024 was stifled by further responsibility as a second
ruck. Following a contract extension to the end of 2029, Owens returned to some of his best form in
2025, kicking 25 goals before a late-season hamstring injury. ==Family and personal life==
