Charlie McAvoy leveled Florida's Sam Reinhart just 20 seconds into the game before David Pastrnak put the Bruins on the board with a first-period power-play goal. That's the start that Boston hoped for after being outscored 12-3 in the previous two losses.

Boston didn't light up the stat sheet with shots early, but Brandon Carlo stayed opportunistic, keeping a loose puck in the offensive zone and ripping a wrist shot from the blue line to double the lead.

Florida took all momentum for an extended stretch from there. The Panthers scored three unanswered goals through the midway mark of the third period from Anton Lundell, Sam Bennett and Aleksander Barkov. Bennett's game-tying score was upheld upon a goaltender's interference challenge from the Bruins.

Florida erased the deficit in deflating fashion for Boston, taking a commanding 3-1 series lead heading back to Florida for Game 5.
