It’s become a pattern now — the Colorado Avalanche look like the better team for the better part of the first 40 minutes and then the final period is a problem.

The 5-10, 175-pound Perunovich logged 18:52 and was a plus-2 with two shots, earning enough of Roy’s trust to play key shifts in the third period. Tony DeAngelo, signed out of the KHL on Friday, played 22:11 with two blocked shots as he also earned his first point as an Islander with an assist in his second game.
