The tensions continued to rise as the period continued and the Blues were able to generate some momentum and a goal as a byproduct.
After a netfront battle between O'Connor and Binnington occurred, a slew of skaters scrambled behind the net resulting in a pair of penalties handed out to two skaters per team. The Blues received the power play though as O'Connor was assessed with slashing and roughing at 15:13.
On St. Louis' first power play of the game, Krug fired a point shot at Georgiev's far pad. The Avalanche netminder made the stop, but the rebound was finished on the doorstep by Schenn at 16:27 to trim Colorado's lead down 3-1.
St. Louis came out with a desperate effort in the final period of play and outshot the Avalanche 10-5 as they made it a one-goal game, but fortunately Colorado was able to outlast them and even add an empty-net goal to seal the victory.
The Blues made it a one-goal game just under the midway mark in the final frame. The play unfolded on an individual effort as Barbashev intercepted a pass and outmuscled Ben Meyers to try and gain possession of the puck. At the blueline of the Blues' offensive zone, Barbashev beat Brad Hunt on a pinch and beat Georgiev with a shot on the fly at 9:40.
After the Blues had pulled Binnington in exchange for the extra skater, the Avalanche cushioned their lead. With three seconds left in the game, Mikko Rantanen sprung Matt Nieto on a breakaway where he put the puck into the open net, marking his first goal since being traded back to the Avalanche on Jan. 25 and his first goal with the club since Feb. 6, 2020.
