Goalie Ukko-Pekka Luukkonen and the Buffalo Sabres finally enjoyed the benefits of playing with a lead. Jordan Greenway scored twice in an outing the Sabres led 3-0 after the first period, and Luukkonen stopped 33 shots for his fourth career shutout and fourth this season in a 7-0 rout of the Los Angeles Kings on Tuesday night. The slow-starting Sabres flipped their script by scoring the opening goal for the first time in eight outings, and holding a lead after 20 minutes for the first time in 11.
