David Pastrnak had a goal and an assist, Tuuka Rask made 36 saves and the Bruins beat the Chicago Blackhawks 4-2 on Tuesday in the Winter Classic at Notre Dame.
Bergeron, Sean Kuraly and Brad Marchand also scored as Boston won for the second time in three appearances in the NHL's annual outdoor game on New Year's Day. The Bruins went 2 for 5 with the man advantage and killed off each of the Blackhawks' four power plays.
The game was tied at 2 when Boston (22-14-4) caught a break in the third period - a little luck at the home of the Fighting Irish. Matt Grzelcyk's big slap shot went off teammate Chris Wagner in front, but Kuraly beat Blackhawks defenseman Gustav Forsling to the rebound and backhanded the puck past Cam Ward at 10:20.
Jonathan Toews sent a shot off the post after the Blackhawks pulled Ward for an extra attacker with about 1:30 left. Marchand then added an empty-netter for his 13th of the season.
Chicago (15-21-6) had won five of six, but it remained winless in an NHL-high fourth appearance in the Winter Classic. It also dropped to 1-5 in six outdoor games - also tops in the league.
Brendan Perlini and Dominik Kahun scored for the Blackhawks, and Ward made 32 stops in his first outdoor NHL game.
Chicago jumped in front when it scored first for the sixth straight game. David Kampf dug the puck out from behind the net and found a wide-open Perlini in the slot 8:30 into the first.
Pastrnak responded with his team-best 24th goal. With Artem Anisimov in the penalty box for tripping, Pastrnak got free in front and slid the puck past Ward at 12:38. He then celebrated by flapping his arms like a bird.
The teams exchanged goals again in the second. Kahun scored his fifth of the season when he redirected Erik Gustafsson's shot by Rask, but Bergeron broke up a potential short-handed breakaway for Kampf before tying it at 2 when he scored another power-play goal with 1:12 left in the period.
The Blackhawks visit the New York Islanders on Thursday night.
