The frustration was evident on a deflated Bruins bench on Monday night.
In the immediate aftermath of Boston’s overtime loss to the Sabres, several players hung their heads on the ice — while starting goalie Joonas Korpisalo slammed his stick as he made his way down the tunnel.
But as the Bruins made their way off the ice following their third-straight loss, Boston’s star winger David Pastrnak opted to give the officiating crew another earful on the frozen sheet.
Beyond the frustrations born out of another frustrating setback, Pastrnak was steamed over the calls on the ice that set the stage for Boston’s eventual 3-2 defeat at the hands of the cellar-dwelling Sabres.
