The Colorado Avalanche have a two-games-to-none lead in the NHL’s Western Conference finals after a flurry of goals and a backup netminder led to a 4-0 shutout of the Edmonton Oilers. Nazem Kadri (NA’-zehm KA’-dree) set up goals by Artturi Lehkonen (LEH’-koh-nehn), Josh Manson and Mikko Rantanen (MEE’-koh RAN’-tah-nehn) during a 2:04 span early in the second period. Pavel Francouz (FRAHN’-sohs) had a 24-save shutout two nights after the Oilers scored six times in a Game 1 loss.
