Callum Penman is a Scottish left-back, born on 5 May 2007 (age 19), whose senior football so far has been centred on St Mirren. Wearing squad number 28, he has been used sparingly, but his route into the professional game has clearly run through Paisley.
His league involvement came in 2024-25, when he made four appearances for St Mirren without scoring. That remains his most active league season, which says as much about the early stage of his career as anything else.
In 2025-26, Penman has yet to make a league appearance, although he has featured once in the League Cup. He remains a young player on the edge of the St Mirren first-team picture, with his career still at the stage where minutes matter more than reputation.
