Johnny Gaudreau, Dillon Dube and Blake Coleman scored in the first period, and Calgary beat the Chicago Blackhawks 5-2 on Monday night.

The Flames clinched a playoff spot on Saturday, and then celebrated with a 9-1 victory over Arizona. They traveled all day on Sunday, yet still had enough to hold off the struggling Blackhawks.

Jacob Markstrom made 22 saves as Calgary (47-20-9) won for the seventh time in eight games. Gaudreau and Oliver Kylington tacked on long empty-netters for the Pacific Division leaders in the final 1:32.

Chicago (25-40-11) lost for the 10th time in 11 games. Tyler Johnson and Alec Regula scored, and Kevin Lankinen made 30 stops.

The Blackhawks played without Mackenzie Entwistle after the forward departed in the first period with a right shoulder injury. King said Entwistle will not travel with the team on its three-game road trip.

Blackhawks forward Kirby Dach missed his second straight game with a right shoulder sprain. King said Dach will not travel with the team for its road trip.

The Blackhawks are at Arizona Coyotes on Wednesday night.
