St Mirren end Rangers' 27-game unbeaten start to season

Rangers were ahead in the seventh minute through defender Connor Goldson but Jamie McGrath equalised from the penalty spot just before halftime and scored again eight minutes after the restart.

Steven Davis struck back for Rangers in the 88th minute before McCarthy smashed the ball home in the 92nd minute to spark wild celebrations and put St Mirren into a semi-final match-up against Livingston.

“This one is on me,” Gerrard said. “We just never performed well enough to get the result we wanted. From a defensive point of view you can’t defend how we’ve defended as a group but ... all the decisions made over the course of the 90 minutes were made by me so I don’t think any finger pointing is deserved right now in terms of the group.”
