Barkov is the first Finland-born player to score four points in a game of the 10 NHL regular-season games played in Finland.

Lindell converted a blind backhand pass from Jason Robertson to make it 3-2 at 1:32 of the second.
Reinhart scored to make it 4-2 with a short-handed goal at 6:07 of the second. Barkov had the primary assist.
