Erik Karlsson collected the game-winner for the Ottawa Senators, who barely slipped past the Buffalo Sabres 1-0 on Friday. Karlsson collected four SOG, which is almost pedestrian for a blueliner who fires an almost unheard of amount of pucks at the net. He logged just under 26 minutes on Friday, so worries about his health might be overblown. Clarke MacArthur and Kyle Turris earned the assists.
