Roloson stopped 38 shots Friday as the Wild pulled out a 2-2 tie with the Detroit Red Wings, giving them a 4-0-3 record over their last seven games.
Roloson, playing in his 20th game, improved his goals-against average to 1.87 -- fourth-best in the NHL through Saturday's games and second only to New Jersey's Martin Brodeur among goalies with at least 15 appearances.
He allowed the Wild to extend their streak despite being outshot 40-24, including 19-6 in the third period.
"Our goalie was really good, especially in the third period," Minnesota coach Jacques Lemaire said. "He had some big saves to make."
The Wild, who have outscored their opponents 22-14 during the unbeaten streak, could easily have earned two points against the Red Wings, but for a goal that was accidentally tipped in by Minnesota's Sergei Zholtok and credited to Detroit's Henrik Zetterberg.
"We played a great game," Roloson said. "Unfortunately, those breaks happen in a game. ... Sometimes a bad bounce happens."
The Flames are coming off Sunday's 2-1 win over the Edmonton Oilers -- their 10th win in 13 games (9-2-1-1).
Miikka Kiprusoff, who owns the NHL's best goals against average (1.45) and save percentage (.943), made 20 saves, and Jerome Iginla had a goal and an assist for Calgary.
"This was a game that, in the past, we might not have won," Iginla said. "But this year, we're finding ways to win these important games. It feels great."
