Corey Crawford stopped 30 shots, while the Chicago Blackhawks got goals from Bryan Bickell and Marian Hossa for a 2-0 win over St Louis on Sunday.
The Blackhawks lead the NHL with 68 points and have won five in a row. They are 3-1 against the Blues, all with Crawford in net.
The Blues rarely tested Crawford until the third period and lost their second straight in front of a standing room-only crowd of 19,385 that had a healthy contingent of Blackhawks fans.
St Louis have seven games remaining in the regular season, all but one at home.
Bickell tapped in his own rebound on a rush early in the second period to end Blues goalie Brian Elliott’s shutout streak at 214 minutes.
Hossa’s short-handed goal off a faceoff win by Jonathan Toews was the crusher early in the third period, coming 17 seconds after Duncan Keith was whistled for cross-checking David Backes in front of the Chicago net.

Tampa Bay have particularly struggled on the road, where they are winless in four straight (0-3-1) and 1-6-1 in the past eight.
