Pavel Zacha scored two goals for Boston (62-12-5), which won its fifth straight game and tied the 1995-96 Detroit Red Wings and 2018-19 Tampa Bay Lightning for most wins in a season in NHL history. Linus Ullmark made 29 saves.
"It's special (to tie the record), no doubt about that," Bruins captain Patrice Bergeron said. "I think all year it's been a lot of fun. I feel like we've stuck to our process, stayed in the moment without really thinking about all the outside noise."
The Bruins will try to set the record when they play at the Philadelphia Flyers on Sunday (6 p.m. ET; TNT, SN1, TVAS, ESPN+, SN NOW).
"Anytime you're talking about putting your team's name, putting our spoked 'B' in the history books, with most wins ever in a regular season, it's special," Boston coach Jim Montgomery said. "Collectively, what's made this season is how hard our guys play for each other."
