Partick Thistle claimed Glasgow bragging rights after securing a narrow Scottish Championship win over Queen’s Park at Hampden.
Logan Chalmers claimed his first goal in Thistle colours after turning home the ball past following a goalmouth scramble.
Brian Graham thought he had doubled Thistle’s lead in the second half after brushing through the Spiders defence to slot home, only for Craig Napier to rule it offside.
Queen’s Park searched in vein for an equaliser, with both Dane Murray and Ryan Duncan forcing saves from Myles Roberts, but were unable to stop Kris Doolan’s side moving above them into fourth.
