What do you call it when Nathan MacKinnon nets three goals in one game?
A Mac-trick.

The Colorado Avalanche forward scored his third goal of Game 5 of the Western Conference Second Round against the St. Louis Blues off an end-to-end rush.
MacKinnon flew into Blues territory, cut the puck tightly in front of and then around Blues defenseman Nick Leddy, and roofed it to put the Avalanche up 4-3 with 2:46 left to play.

With the Avalanche up 3-1 in the series, MacKinnon became the first player in franchise history to score a hat trick in a potential series-clinching game.
The Blues, however, won 5-4 in overtime.
