Zack Bolduc scored twice for the Blues (43-28-7, 93 points), who improved to 19-2-2 in their last 23 games.

Ross Colton, Miles Wood, Nathan MacKinnon and Sam Malinski scored for the Avalanche (47-27-4, 98 points), who suffered just their second regulation loss in their last nine games.

The Blues needed just 49 seconds to take a 1-0 lead. St. Louis received a power play in the game’s first minute and capitalized when Thomas set up Bolduc’s goal from the low slot.

Neighbours made it 2-0 by driving to the net and converting Thomas’ pass from behind the net at the 7:41 mark.

The Blues increased their lead 61 seconds into the second period. Jimmy Snuggerud shoveled a pass to Buchnevich for his uncontested reach-around shot.

Bolduc scored his second power-play goal at 8:53 of the period. Once again, he took a pass from Thomas from the left flank and scored from the slot.

Colton broke through for Colorado with 4:28 left in the period. He drove to the net and converted Logan O’Connor’s pass from the right wing.

Wood cut the Avalanche’s deficit to 4-2 just over two minutes later, scoring from point-blank range off Charlie Coyle’s pass.

With Blackwood off the ice for an extra attacker, MacKinnon cut the lead to 4-3 with 2:18 left with a shot off Blues defenseman Justin Faulk.

Thomas made it 5-3 with an empty-net goal with 30.1 seconds left. He extended his point streak to eight games; he has four goals and 15 assists during that span.

Malinski scored at 19:51 to cut Colorado’s deficit to one goal.
