Nine seconds into the game, the gloves were off as a scrap between Ross Colton and Jakub Lauko sparked things before Pat Maroon and Garnet Hathaway found each other for an extended tilt in front of the benches.
Tampa Bay ended up with an extra two minutes of penalty time and went to the penalty kill, which they had to do a ton during the opening 20 minutes. The Lightning were able to get the penalty killed off, but took two more minor penalties over the first 5:33 of the game before Boston capitalized and made it 1-0.
But even on the go-ahead goal scored by Patrice Bergeron, the Bolts were doing the right things. Victor Hedman had Bergeron tied up in front of the net and had taken away his stick, but a pass from Brad Marchand ricocheted off the skate of Bergeron and got behind Andrei Vasilevskiy.
Playing with fire, Tanner Jeannot sent the Bruins back to the power play, this time a four-minute man advantage, when he was whistled for a double minor high-sticking penalty at the 8:19 mark of the first.
At a huge moment in the game, Tampa Bay needed their leaders to step up and Hedman placed the responsibility on his shoulders, tying the game with his first career shorthanded goal 1:11 into Boston's power play.
The play started when Pierre-Edouard Bellemare made a heady, patient play in the neutral zone to hold the puck before finding Killorn near the Boston blue line. After Killorn entered the offensive zone, he sent a pass towards Bellemare, who quickly adjusted, got his blade on the puck, and directed it to Hedman, who hammered a slap shot from the top of the circle that got redirected off the stick of Charlie McAvoy and beat Linus Ullmark top shelf.
The Bolts carried that intensity into the middle frame and continued to play hard, but the Bruins would regain the one-goal lead when Garnet Hathaway was left unchecked in front of the net and pounced on a rebound in front of Vasilevskiy to put Boston up 2-1 with 2:28 remaining in the second.
Entering the third period trailing by one, the Lightning continued to push, but just couldn't find a way to get another shot past Ullmark before falling by a final score of 2-1.
