Cale Makar also scored, Parker Kelly had two assists, and Mackenzie Blackwood made 25 saves.
Dalibor Dvorsky scored, and Jordan Binnington made 30 saves for the Blues (1-1-0), who won 4-0 at the Dallas Stars on Friday.
Makar scored to make it 1-0 Colorado at 4:09 of the first period when he finished a passing play with a wrist shot inside the right post. MacKinnon took the puck down to the left face-off circle and fed it over to Necas in the slot, where he then backhanded a pass to Makar at the backdoor.
Necas extended the lead to 2-0 at 13:12 of the first period when he beat Binnington’s glove far side with a wrister from inside the left circle. Lehkonen knocked Robert Thomas’ clearing attempt near the right wall back to MacKinnon, who fed a cross-ice pass to Necas all alone on the opposite side.
Manson pushed it to 3-0 at 5:38 of the second after his one-timer from the blue line deflected off the stick of Blues forward Jonatan Berggren and fluttered past the blocker.
Lehkonen made it 4-0 at 11:40, knocking down Binnington’s outlet pass from behind the net at the right circle and snapping the puck low past the sliding goalie.
Roy scored to make it 5-0 at 18:02 when he wristed Parker Kelly’s drop pass in the left circle to the short side.
Necas scored his second of the game to make it 6-0 at 18:25, backhanding Gabriel Landeskog’s centering pass into an open net from atop the crease. Binnington was out of position after getting behind the net to play the puck, but it skipped over his stick and went to Landeskog.
Dvorsky cut the deficit to 6-1 at 2:34 of the third period after he located a loose puck in the high slot and backhanded it far side past the glove of Blackwood.
