Rookie Jeremy Morin scored and set up Patrick Sharp's go-ahead goal in the second period, and the injury-depleted Chicago Blackhawks held on to defeat the St. Louis Blues 4-2 on Sunday afternoon for their third straight win.
The Blackhawks ground out the victory despite skating without injured star forwards Jonathan Toews and Patrick Kane for the third game. Forward Brandon Saad was a last-minute scratch.
Marcus Kruger and Ben Smith also scored for Chicago, which closed to one point behind Colorado for second place in the Central Division and home ice in the first round of the playoffs. The Blackhawks have three games left. The Avalanche, who host Pittsburgh on Sunday night, have five games left.
Jaden Schwartz and Vladimir Sobotka connected for St. Louis, which lost its second straight and remained two points behind idle Boston for the NHL's overall point lead and race for the Presidents' Trophy.
