In the extra session, Henrik Sedin had the puck behind the net and dished it to the front where his brother one-timed it home for the win.
The first goal of the game happened 7:58 into the first period when Kesler got the puck in the slot and snapped a shot into the right side of the net.
Chicago, though, tied the game with 8:49 to play in the first as Mayers got the puck down low and was able to snap it home.
The second period passed scoreless, but Chicago took a 2-1 lead 1:17 into the third when Patrick Kane's pass from the low right side went off an Edmonton stick and found its way to the slot where Stalberg was able to send a backhander home.
Less than three minutes later Hodgson was sprung on a breakaway and his quick shot went into the right corner.
