A triple premiership defender, Vlastuin finished second in the Jack Dyer Medal count in both 2024 and 2025 — his 5th top-four result — and earned his second All-Australian squad selection before a broken ankle in Round 23 ended his season. Richmond's most experienced current player and a life member, the 187cm Vlastuin wears the No.1 guernsey. He has played 277 AFL games and kicked 30 goals.
