Patrick Sharp had a goal and two assists for Chicago, which has won three in a row after a three-game losing streak.
Michal Handzus scored a short-handed goal in the second and Marian Hossa had three assists, helping rookie goaltender Antti Raanta win his second consecutive start in place of injured Corey Crawford.
The seven goals set a season high for the Blackhawks (23-6-5), who have scored 19 times during their winning streak and lead the NHL with 129 goals.
RED WINGS: Goalie Jimmy Howard injured a knee during practice Wednesday.
That led to the Red Wings recalling Petr Mrazek from the AHL’s Grand Rapids Griffins and putting forward Henrik Zetterberg on long-term injured reserve.
The Red Wings have ruled Howard out for tonight’s game at Tampa Bay and plan to reevaluate him Friday in Detroit.
SUSPENDED: Ottawa defenseman Jared Cowen was suspended for two games by the NHL on Wednesday for a hit to the head against Buffalo’s Zemgus Girgensons.
Cowen struck Girgensons late in the third period of Ottawa’s shootout loss game in Buffalo on Tuesday night. No penalty was called on the play. Girgensons scored the shootout winner.
The suspension will cost Cowen $31,795.
