The breakthrough came when MOTM Patrick Roberts' shot was blocked, falling to Rogic to smash home on 50 minutes. And it was two when, as Rangers searched for an equaliser, a ruthless counter attack say Robets cut in from the right wing and set up Griffiths for a clinical first time finish.
Rangers had felt they should have had a first half penalty when Morelos was tackled by Simunovic, who didn't appear to get a touch on the ball.
Griffiths could have opened the scoring for the visitors on nine minutes but he headed Tierney's cross over. rangers keeper Foderinham also made good saves from both Rogic and Griffiths to keep the scores level at the break.
