The Bruins and Flyers took the ice for the third period on Saturday knotted at 2-2, following a relatively even first 40 minutes.
Less than five minutes into the frame, Boston had a sudden and jarring 5-2 lead.
Charlie Coyle was the catalyst for a major momentum shift that led to the rapid scoring spree, in which the Bruins scored three times in less than three minutes, and two goals 19 seconds apart. The center scored the game’s tying goal late in the second period, and gave Boston its first lead of the night a minute into the third.
