Charlie McAvoy had an assist, three shots on goal and was plus-4 in 24:16 of ice time in his return for Boston. He had missed the previous 11 games after he was hit in the face with a puck in a game against the Montreal Canadiens on Nov. 15, an incident that required facial surgery.

Barron made it 1-0 Jets with his first goal in 20 games at 5:59 of the first period. Josh Morrissey’s point shot created a scramble in front, and Barron was able track and jam in his own rebound.
Boston then scored three goals in a span of 2:44.
Pastrnak tied it 1-1 on the power play at 8:24, beating a screened Comrie with a snapshot from the top of the right face-off circle.

Sean Kuraly pushed it to 3-1 at 11:08. Tanner Jeannot entered the offensive zone and chopped it into the slot where Kuraly gloved the puck down and lifted a backhander over the outstretched glove of Comrie.
Iafallo cut the deficit to 3-2 at 13:37 on a net drive, lifting it short side over Korpisalo’s glove from in close.
Lindholm extended the lead to 4-2 at 14:36 with a slap shot from above the left circle.
Vilardi then cut it to 4-3 on the power play at 17:46, banging in a rebound after Cole Perfetti’s shot bounced across the crease.
Elias Lindholm scored to make it 5-3 at 14:43 of the third, and Pastrnak had an empty-net goal at 18:04 for the 6-3 final.
