Jarryn Geary

At the end of the 2007 season, Geary was elevated onto St Kilda's primary list for 2008.[5] His career started positively, playing in the pre-season 2008 NAB Cup competition which St Kilda won in the final against Adelaide.

In Round 1, 2008, Geary made his home and away season debut for the Saints, gathering 21 possessions as one of the best-on-ground players against the Sydney Swans.[6] He played a total of 10 games in 2008, a season which ended at the Preliminary Final stage for the Saints. Geary was nominated for the AFL Rookie of the Year award, the Rising Star, for his 19-possession game against Essendon in Round 8.[7]

Geary played in 15 of St Kilda's 22 matches in the 2009 home and away rounds, with a 100% record of 15 wins, averaging 16.9 disposals per game. He played the first 14 games in a row, then his only further appearance for the season was in the Round 19 win over Hawthorn. St Kilda dominated the competition and qualified in first position for the AFL finals series, winning the minor premiership McClelland Trophy. Geary was not selected to play in any of St Kilda's finals matches.

In 2010, Geary played in 19 of St Kilda's 22 home and away matches, averaging 16.5 disposals per game. St Kilda qualified third for the AFL finals series, but Geary was again overlooked for the finals, not being selected for any of the Saints finals matches.

Geary was not selected to play in the 2011 premiership season until Round 18 against Adelaide, playing every game for the remainder of the season. He played in his first finals match in the losing second eliminati'son final which ended St Kilda's season.

In the 2012 and 2013 seasons, Geary played 20 and 21 games respectively, averaging 17.6 disposals per game for both seasons. He had his most productive career match in the final game for the year, the Round 23 match against Fremantle at Docklands Stadium, which was notable as being the final game for Saints legends Justin Koschitzke, Jason Blake and Stephen Milne. St Kilda won the match by 71 points. A broken arm ended Geary's season in the Round 7 of 2014.

In the 2015 season, Geary again play mainly across half-back, where he solidified his reputation as a dependable and courageous defender. He played 20 games for the season, averaging 19.2 per game. In 2016, Geary played 21 games, averaging just over 15 disposals per game.

In 2017, Geary took over as captain from St Kilda's longest-serving captain, Nick Riewoldt, in what was to be Riewoldt's final season as a player.[8] He played every game for the year, averaging 16 disposals per game, with St Kilda finishing 11th on the ladder. Geary was again prominent in 2018, in what was a difficult year for the Saints, playing in 20 of St Kilda's 22 matches. He had his most productive season at the Saints, average over 20 disposals per game for the first time in his career. In 2019 he played four of the first five games before being injured and did not play again until the round 11 against Port Adelaide held in China. Geary suffered a serious broken leg in the match which ended his season.

Geary again captained the Saints in a 2020 season disrupted by the COVID-19 pandemic. Matches were reduced to four fifths of full length (16 minutes plus time on per quarter) and the season as a whole was reduced to 17 home and away matches. In a season that was rescheduled regularly during the year, with games schedules released in small blocks, St Kilda proved to be resilient to the disruptions, despite the hardships caused by the ad-hoc scheduling. Big wins over the Sydney Swans in the annual Pride Game by 53 points, and over GWS Giants by 52 points in the final round, both at the Gabba, helped secure St Kilda's finals series qualification. St Kilda won the second elimination final, with Geary playing as a defensive forward. He kicked three goals, including the Saints' final goal, also being involved in other scoring chains, and had 12 disposals. St Kilda lost the following week's semi-final.

Jack Steele joined Geary as co-captain ahead of the 2021 season. St Kilda finished 10th and missed the finals series. The round 12 match against the Sydney Swans turned out to be Geary's last game.

On 14 July 2022, after not playing an AFL match during the season, Geary announced his retirement from AFL football after 16 seasons and 207 games for St Kilda. He was awarded honorary life membership to St Kilda for playing 150 games or more.[9]
