Calgary is the only NHL team to finish the preseason without a loss. Edmonton was 4-2.
The only goal came at 5:36 of the first period as the Flames' top line of Jarome Iginla, Olli Jokinen and Tanguay connected on a power play.
Edmonton goaltender Devan Dubnyk failed to corral the puck after it caromed off the end boards and in front of the net. In the ensuing scramble, Tanguay jabbed the puck inside the far post for his first goal of the preseason.
Kiprusoff's best stop came four minutes into the third period. The 33-year-old veteran sprawled across the crease as he followed the Oilers' Jordan Eberle, then acrobatically kicked up his top pad to knock away Eberle's shot.
