St. Louis improved to 7-3 when leading after 20 minutes by responding well to yet another poor look on special teams: The Blues killed off a Bruins power play and then hemmed Boston in its own end for more than three minutes. While St. Louis cycled the puck in the offensive zone and changed several forward lines and defensive pairings, Boston defenders were gassed and Connor Clifton took a penalty for an illegal check to the head of Tarasenko.
