Nazem Kadri scored three goals, including two during a four-goal second period barrage, and the Colorado Avalanche beat the St. Louis Blues 6-3 on Monday night to take a 3-1 lead in their Western Conference series.

Kadri's outburst came after he received racist death threats on social media following a first-period collision with Blues goalie Jordan Binnington in Game 3 on Saturday night.

Kadri, who was booed heavily every time he touched the puck, skated towards the glass and appeared to salute the Blues fans after each of his first two goals, inciting even more jeers. It was his first career playoff hat trick.

Erik Johnson and Devon Toews also scored and Mikko Rantanen added an empty netter for the Avalanche, while Darcy Kuemper made 17 saves.

David Perron scored twice and Pavel Buchnevich had a goal and an assist for the Blues. Ville Husso, making his first start since Game 3 of the first round against Minnesota, made 31 saves.

The Avalanche took control of the game - and the series - with three goals in less than a two-minute span early in the second period.

Perron and Buchnevich each scored power play goals late in the second to bring the Blues back within one, but Kadri's goal midway through the third scuttled the comeback attempt.

Game 5 is Wednesday in Colorado.
