Colorado was already in front heading into the dying moments, but caught fire late to give the match an ugly scoreline.
After 50 scoreless minutes Tony Cascio gave the Rapids a lead with the first goal of the night. From Colorado's first corner of the match Cascio took the ball down into space and sliced a left-footed shot across goal and into the side netting.
Despite the goal, the match seemed destined to be a low-scoring affair until the 82nd minute when Kamani Hill slotted home on the break to make it 2-0 and open the floodgates.
Jeff Larentowicz slotted home a penalty in the 84th minute after Ante Jazic pulled him down in the box, and Hill rounded out the night with his second at the death.
