"He's one of our leaders, he's one of our core guys," Flames coach Darryl Sutter said of Markstrom. "It's not always easy to do from that position because guys are sort of on their island a little bit, but he brings a lot to the locker room."
Gaudreau had two goals and an assist, Tkachuk had a goal and two assists, and Andrew Mangiapane scored twice for the Flames (9-3-5), who had lost four of five. Chris Tanev had two assists, and Markstrom made 27 saves in his 13th start.
"We got off to an early lead, and didn't really look back," Tkachuk said. "In the third, we were kind of just playing for 'Marky' there. He also did a great job but was tested more than we'd like. … But all in all, just a solid game. And anytime you are up 5-0 after two, you are in a good spot for the third."
