Florida made it 1-0 at 4:22 of the first period when Eetu Luostarinen jumped on a turnover deep in the Boston zone and beat Korpisalo glove side with a wrist shot.
Eyssimont tied it 1-1 at 7:18, scoring through the five-hole on a breakaway, then came out of the penalty box and gave the Bruins a 2-1 lead at 12:43 on another breakaway. He took a stretch pass from Marat Khusnutdinov, deked Bobrovsky and stuffed the puck in at the right post.
“I didn’t even see [Khusnutdinov] take a look, he just knew,” Eyssimont said. “Good awareness for him to know the time and he got the puck to me. I was feeling it, felt good. I knew I could do something in tight.”
Balinskis tied it 2-2 at 30 seconds of the second period with a power-play goal, taking a pass from Tkachuk and sending a wrist shot past Korpisalo.
Tkachuk then put Florida in front 3-2 on the power play at 2:47 when he banked his own rebound off Korpisalo from behind the goal line.
Lundell pushed the lead to 4-2 at 18:33 with a short-handed goal on the rush, finishing a give-and-go with Sam Reinhart.
