CHICAGO -- Goaltender Corey Crawford stopped 25 shots to earn his league-leading seventh shutout, and the Chicago Blackhawks cruised to a 2-0 win over the St. Louis Blues on Sunday night.

Left wingers Artemi Panarin and Andrew Shaw scored for the Blackhawks. Chicago (33-15-4) snapped a two-game losing streak and improved to 21-5-1 on home ice.

St. Louis (28-16-8) lost in regulation for the first time in five games. The Blues were shut out for the fourth time this season and the first time since Dec. 27.

Crawford stopped 12 shots in the first period, six shots in the second period and seven shots in the third period to improve to 28-11-2. He has posted five shutouts since Dec. 11.

St. Louis goaltender Brian Elliott turned aside 23 of 25 shots in the loss.

Panarin scored on a one-timer to put Chicago on top 1-0 with 4:34 left in the second period. Right winger Patrick Kane carried the puck into the offensive zone and zipped a backhand pass to Panarin, who fired a rising shot past Elliott's glove for his 17th goal of the season and his first goal in the past five games.

Chicago increased its lead to 2-0 on a power-play goal by Shaw with 15:04 to go in the third period. Right winger Marian Hossa ripped a one-timer from the top of the right circle, and Shaw lifted his stick parallel to the ice to deflect the shot past Elliott for his ninth goal.

Crawford stymied St. Louis after enjoying a rare night off one game earlier against the Florida Panthers. The 31-year-old netminder denied a rising wrist shot by Blues defenseman Joel Edmundson and a slap shot by defenseman Colton Parayko during a frenzied start to the first period.

Chicago scored on its lone power-play opportunity. St. Louis was 0-for-1 on the man advantage.
