After Zegras cut Boston's lead 2-1 late in the first period, cameras caught him yelling at Trent Frederic. Not long after, a scrum ensued as Brad Marchand took exception.
Postgame, Matt Porter of the Boston Globe asked Pasta about the incident:
''Yeah, for sure. You can't do that after a goal. You have to have some certain respect. You can't score a goal and yell at the opponent, no matter what happened in the sequence before.''
Pastrnak lead the way with a hat-trick, getting up to 32 on the season and one behind Connor McDavid for the league lead.
