Midfielder Stuart had already featured for the reserve team before joining the club full-time as a modern apprentice in the summer of 2009.
After impressing during pre-season, Stuart made his first team debut for Thistle against Clyde on the opening day of the 2010-2011 season.
Stuart spent much of the latter half of season 2010-2011 on loan with Ayr United and he helped them to promotion to the First Division via the end of season play-offs.
In the second half of season 2011-12, Stuart really started to establish himself in the Thistle first team, scoring his first goal on the final day of the season at Hamilton and showing he can play in a number of positions, filling in at left back from his more usual central midfield role.
Stuart really began to shine during the 2012-13 championship winning season, establishing himself as one of the club’s most promising stars and he was rewarded when he was selected for the Scotland Under-21 side in an away match with Greece before winning a further cap later in that season.
Stuart adjusted easily to life in the top flight of Scottish football and continued his excellent form at the heart of the Thistle midfield. He was rewarded with a new two year contract that will keep him at Firhill until at least the summer of 2016.
Stuart maintained his tough tenacious style of play in the heart of the midfield as he became an automatic selection choice for Alan Archibald. In October 2015 Stuart made his 150th Thistle appearance in a fixture against Hamilton Accies.
