Johnny Gaudreau had a goal and two assists, Matthew Tkachuk scored for a third straight game and the Calgary Flames beat the Chicago Blackhawks 5-1 on Sunday night.

Elias Lindholm and Trevor Lewis also scored for Calgary, Oliver Kylington added a long empty-netter and Jacob Markstrom blocked 30 shots in the Flames' second straight win. Calgary is coming off a COVID-19 outbreak that shut the team down from Dec. 11 until Dec. 30, when they topped the Kraken in Seattle.

The Flames have roared back with 11 goals in two games, while allowing five, and their top line of Gaudreau, Tkachuk and Lindholm has led the way. Gaudreau has been as slick as ever with three goals and three assists in the two wins.

The Flames took charge in the second period, outshooting Chicago 26-9 in the frame to tie a franchise record for shots in a period.

Alex DeBrincat scored his team-leading 18th goal, but Chicago dropped its fourth straight.

Arvid Soderblom made his first NHL start with 37 saves, including one on Dillon Dube's third-period penalty shot. Soderblom made his NHL debut Saturday, playing the second and third period of Chicago's 6-1 loss at Nashville.

Chicago interim coach Derek King said his team had only a few ''passengers'' Sunday after he thought nearly half his players weren't ready in a 6-1 loss at Nashville on Saturday. And King was impressed with the 22-year-old Soderblom, saying ''the poor kid played a hell of a game for us.''

Marc-Andre Fleury, the Blackhawks' top goalie, returned from COVID-19 protocol Sunday and was on the bench the as the backup.

Sunday's game was Chicago's second in two days after a 13-day layoff when four of its contests were postponed because of COVID-19. The Blackhawks played their first home game since Dec. 17 in an uncharacteristically quiet United Center, where there were plenty of empty seats.

The Blackhawks host Colorado on Tuesday.
