The Bruins, coming off an intense 3-2 loss Wednesday night at Washington in a matchup of the NHL's top two teams, hadn't dropped four consecutive games in regulation since March 2017. The five-game losing streak is their longest since an 0-5-0 stretch in March 2016.

Not long after Stamkos gave the Lightning a 3-1 lead at 15:13 of the third period, Moore got his first goal since returning from shoulder surgery with 3:15 left.

Stamkos also scored from the slot during a power play, tying it 1-all at 12:35 of the second. The Lightning star tied Bernie Nicholls and Yvan Cournoyer for 46th place on the NHL list with 152 career power-play goals.

Boston went up 1-0 at 4:26 of the first when Brad Marchand skated along the left wing boards and went around the net before making a nice pass to Bergeron in the low slot.
