Richmond (2017–2018) during VFL match in July 2017 Stengle was drafted by with the club's first pick and the sixth selection overall in the
2017 AFL rookie draft. Stengle played in the early part of the 2017 season with Richmond's reserves side in the
VFL. He was a key forward-line player for the side, kicking 13 goals in his first eight matches. He made his AFL debut two weeks later in Richmond's round 15 win over at the
Adelaide Oval where he kicked two goals in the match. He played again the following match but was omitted from the team's round 17 side to play the week after. From there he returned to the club's reserves side, playing with the team through to their finals campaign. There he played in each of their three victories, and in the team's losing grand final against
Port Melbourne. Stengle finished the 2017 season having played two matches and kicked two goals at senior level. In February 2018 Stengle was selected alongside most of the club's younger players to represent Richmond at the Sydney tournament of the
AFLX exhibition series. He started the season-proper with the club's reserves side, but was immediately impressive at that level with a 20 disposal and three-goal game in round 1. By round 5 he was named as an emergency for the AFL team, but ultimately went unselected at the top level. In mid-May Stengle turned in a three-goal third quarter during a VFL match with North Melbourne that saw him again named an AFL emergency the next week. He began playing limited midfield minutes in VFL matches from June, adding positional versatility to his predominantly forward-line role. In mid-July Stengle turned in his best performance of the year to-date, kicking a bag of six goals while gathering 24 disposals in Richmond's VFL win over North Melbourne. For that performance he was noted by head coach
Damien Hardwick as one of the club's best VFL performers, but went again un-selected for senior football. To that point he had played 13 matches at the lower level for a total of 26 goals, the most for any Richmond player and the sixth most of any player in that league. Two weeks later Stengle suffered a minor ankle injury while playing in a VFL match against . He missed the second half of the match due to the injury as well as one further match while rehabilitating the injury. Stengle finished the home and away VFL season with 33 goals, good for eighth most of any player in the league. He did not add to that tally in the VFL finals series however when Richmond's reserves side were eliminated following consecutive losses to and . He won the club's reserves goal-kicking medal for his 33 goals over 19 matches in the VFL, but failed to earn an AFL match in 2018. Less than a week out from the beginning of the trade period, Stengle requested a trade to Adelaide citing a lack of AFL-level opportunity during his time at Richmond.
Adelaide (2019–2020) On the penultimate day of the
2018 trade period Stengle was traded to in exchange for a 4th round draft selection in pick 68. Stengle's career with the Adelaide Football Club ended when he was delisted on 17 March 2021 prior to the
2021 AFL season as a result of a settlement relating to off-field incidents.
2021 In 2021 Stengle returned to his original club, the
Woodville West Torrens Eagles where he played a major role in their back-to-back
SANFL premiership, which underpinned a possible return to the AFL for 2022. On 5 November 2021 Stengle signed with as delisted free agent.
Geelong (2022–) After receiving a lifeline by Geelong at the end of 2021, Stengle made his club debut in Round 1 against Essendon, kicking a career-high four goals.

All-Australian team, followed by a part in Geelong's
2022 premiership team. On the 30th of June 2024, Stengle signed a five-year contract extension with Geelong, which will see him play for the Cats until 2029. ==Statistics==
