Matthew Tkachuk had a career-high five assists, Johnny Gaudreau had a goal and three assists, and the Calgary Flames routed the St. Louis Blues 7-1 Monday night.

Tkachuk ended a four-game goal-scoring streak but was happy to spread the wealth. Four of his assists came in the second period, when Calgary outshot St. Louis 18-2.

Tkachuk has 17 points (four goals, 13 assists) in 13 career games against his hometown team.

Nikita Zadorov, Chris Tanev, Elias Lindholm, Sean Monahan, Blake Coleman and Adam Ruzicka also scored for Calgary (19-12-6), which won for just the second time in seven games.

Tyler Bozak scored for St. Louis (25-12-5), which had won six of its previous seven.

Jacob Markstrom made 20 saves to earn the victory and improve to 14-9-5.

Jordan Binnington stopped 28 of 35 shots before being replaced by Ville Husso to start the third. Husso stopped all 13 shots he faced.

Gaudreau and Tkachuk have both been on a tear, combining for 24 points over the last five games. During their five-game point streaks, Gaudreau has 11 points (two goals, nine assists).

Calgary went 2 for 5 on the power play against the Blues' fourth-ranked penalty kill, which was a perfect 12 for 12 in the previous three games. St. Louis's second-ranked power play went 0 for 2.

The Blues host Calgary on Thursday.
