BOSTON — Charlie Coyle and Jake DeBrusk scored in Boston’s two chances in the shootout and the Bruins, with newcomer Taylor Hall, rebounded for a 3-2 victory over the Buffalo Sabres on Tuesday night. Craig Smith and David Krejci scored in regulation for Boston, which had lost its last two games but improved to 4-2-1 in its last seven. Former University of Maine goalie Jeremy Swayman made 21 saves for the Bruins and stopped Buffalo’s two shootout attempts. “I heard he was really good at them, and obviously he was,” Boston coach Bruce Cassidy said of Swayman’s first NHL shootout. Colin Miller and Rasmus Dahlin scored in regulation for the Sabres, who had won three of their last four.
