The Kings, who outshot Colorado 46-21, scored twice in the third
period to cap a dominating performance.

he stopped 20 of 21 shots for his first victory of the preseason.
After a scoreless first period, Robitaille found the back of the
net 2:56 into the second. Armstrong and Mattias Norstrom assisted
on the goal, Robitaille's third of the preseason.
