Bojan Miovski's cute dink in stoppage time sealed a dramatic 1-0 victory for Rangers over St Mirren and extended their winning run to four games in the Scottish Premiership.
The substitute raced onto Ryan Naderi's flick-on from Ivor Pandur's long ball before lifting a delightful lob over the goalkeeper to send Ibrox wild after a drab 90 minutes.
It looked for all the world that Derek McInnes' side were set to be frustrated after struggling to break down a resolute St Mirren side who packed a punch of their own.
St Mirren could easily have taken all three points, having created the clearest chance of the game when Fraser Taylor was sent through one-on-one with Ivor Pandur.
In a miss that would prove costly, the forward had time to pick his spot, but his effort was too close to the Rangers goalkeeper, who made a comfortable save.
The victory moves Rangers above St Mirren and into second in the Scottish Premiership, with the visitors suffering a second consecutive league defeat after their 2-1 loss to Celtic last time out.
Rangers had to cope without captain and striker Lawrence Shankland, who missed out through injury, with Ryan Naderi starting in his place.
But it was another substitute who provided the decisive moment as Miovski produced a composed finish to ensure Rangers' momentum under McInnes continues.
Rangers turn their attention to a huge double-header against Celtic, with the sides first meeting in the League Cup quarter-finals before renewing hostilities in the Scottish Premiership at Parkhead.
