EDMONTON, Alberta (AP) — Half of the Stanley Cup showdown is set. Artturi Lehkonen scored 1:19 into overtime, and Colorado rallied to beat the Edmonton Oilers 6-5 last night, completing a four-game sweep and sending the Avalanche to the Stanley Cup Final for the first time since 2001. Colorado will take on the winner of the Eastern Conference final between the New York Rangers and two-time defending Stanley Cup champion Tampa Bay Lightning. The Rangers lead that best-of-seven series 2-1.
