A blistering first 15 minutes seen Rangers stun Hamilton and secure their spot in the next stage of the Scottish Youth Cup.
Both teams were coming into the game with convincing victories in the previous round, Hamilton winning 8-1 and Rangers winning 9-1.
The goals in this game started almost instantaneously with Rangers taking the lead within 3 minutes after Hannah Robinson was able to slip through Reanna Bates who was there to roll the ball into the bottom corner.
However, within 15 minutes, Rangers were 6 goals to the good with Rosie McQuillan putting away 3, Bates adding another goal to her name, however the pick of the goals came in the form of O'Brien's goal when she showed some lovely skill in the middle of the park before rifling home from 25 yards out.
Rangers were showing their goal scoring form that they showed in the last game and on the stroke of half-time after McQuillan completed a mazy run and put it back for Christie, who putt it away to make it 7-0.
