Steven Gerrard’s men had to come from a goal behind to beat the Buddies in Paisley.
Connor Ronan opened the scoring with a screamer as St Mirren started brightly, putting Rangers under a lot of pressure.
The Ibrox side built into the game, however, and netted quickfire goals just before half-time. Kemar Roofe scored from the penalty spot after Ianis Hagi was felled before Alfredo Morelos converted a James Tavernier cross for his 100th goal for the club.
Rangers saw the game out without too much trouble.

. Jon Mclaughlin - 6
Beaten by an unstoppable effort from Ronan. Plenty of touches of the ball but wasn’t called into that much action after the early Saints goal. Photo: Craig Williamson - SNS Group
. James Tavernier - 7
Sloppy play in the build-up to St Mirren opening the scoring but came to the fore in an attacking sense. Delivered some great crosses, including the one for Morelos’ goal, and was a threat with his runs. Photo: Craig Foy - SNS Group
. Connor Goldson - 7
Went about his business with minimum fuss as he tends to do. Brophy started lively but Goldson had him under control. Photo: Craig Foy - SNS Group
5. Borna Barisic - 6

6. John Lundstram - 6
Beaten too easily for the opening goal. But steadied and provided Rangers with a platform alongside Davis. Photo: Craig Foy - SNS Group
7. Joe Aribo - 7
Not as dominant as he was in Thursday’s win over Brondby. Grew into the match and showed a grittier side to his game. Photo: Craig Foy - SNS Group
8. Steven Davis - 6
Started poorly with some slack play. Improved but still not at the standard many would expect from such a controlling presence. Photo: Craig Foy - SNS Group
