Graves broke a scoreless tie at 1:57 of the second period. Graves, who had just gotten out of the penalty box, beat Binnington in a race for a loose puck in left circle and chipped it in the empty net.

The Blues unsuccessfully challenged for goaltender interference — giving the Avalanche a power play. But Bozak scored a short-handed goal just nine seconds into the penalty kill to cut the Colorado lead to 3-1.

Newhook made it 2-0, burying a rebound off a slap shot by Graves with 7:23 left in the second.

Colorado added to its lead with 3:52 left in the second on a diving swipe of the puck by Jost, finishing off a rush moments after Grubauer got in front of a point-blank chance for Jordan Kyrou.

Grubauer was stellar from the start, making 25 saves in the first two periods and several more in the third period as a desperate Blues team tried to come back.

Saad’s second goal of the playoffs with 6:18 left in the third sealed the win for the Avalanche. Compher added an empty-net goal.
