David Pastrnak didn't have a shot. His back was to the net, but the Bruins forward took the chance and tied the game for Boston.
Pastrnak took the pass from Brad Marchand and, without a clear path to the net, put the puck between his legs on the backhand and beat Panthers' goaltender Sergei Bobrovsky for Boston's second power-play goal of the night.
The Bruins thought they took the lead for the first time just a few minutes later when Brandon Carlo beat Bobrovsky, but the goal was disallowed for a hand pass. Florida took the 3-2 just minutes later.
The Bruins are looking to close out the best-of-game series and send the Panthers home for the summer.
