On Saturday, Roloson bested Kolzig in a 1-0 victory as he made 17 saves en route to his eighth career shutout. He took a 2-0 lead deep into the second period in this one before defenseman Sergei Gonchar halved Washington's deficit.
The Capitals tied it just over 6 1/2 minutes later, when defenseman Ken Klee backhanded the puck past Roloson for his first goal of the season.
But Washington was penalized for having two many men on the ice at 15:44 and Minnesota needed just 57 seconds to regain the lead. Brunette, who broke into the NHL with the Capitals, deflected a puck off Kolzig's skate for his eighth goal.
Antti Laaksonen and rookie Stephane Veilleux also tallied for Minnesota, which had a 35-24 edge in shots.
