Andrew Peeke scored and Swayman made 18 saves for the Bruins (20-18-2), who have lost six straight games (0-4-2), including the first two on this five-game road trip.
“A point is a point. We take that anytime on the road. Do we want two? Yes, but again, I feel good about that point,” Bruins coach Marco Sturm said. “These guys have been pretty good at home, they've been pretty good the last 10 games as well, so we want to build on that. We have to. It's a tough League and you’ve got to sometimes start with the little things.”
The Bruins penalty kill was active all night, with the Flames going on the power play five times throughout the game. Despite two Calgary power plays in the third period, Boston still controlled play, giving up just one shot the entire period. Boston's penalty kill, which fought off the first two Flames scoring chances on the power play in overtime, was finally beaten by a bounce on the 4-on-3.
“We felt like, for a good amount, we were in control,” Peeke said, despite the adversity. “Hockey is hockey, there's going to be chances both ways but we played pretty tight. … Got to keep building off this.”
Peeke put Boston ahead 1-0 at 18:06 of the first period after fellow defenseman Mason Lohrei kept the puck in at the blue line and spotted him along the left boards. Peeke took the puck to the net and had it knocked off his stick by Calgary defenseman Hunter Brzustewicz in tight, but it deflected off Peeke's left skate and in under Wolf.
Calgary challenged the play unsuccessfully for goalie interference.
Coleman tied it 1-1 at 13:32 of the second period with his team-leading 12th goal, taking a backhand pass from Mikael Backlund at the left face-off dot and getting a quick wrist shot through the legs of Bruins defenseman Charlie McAvoy and under the blocker arm of Swayman from the left hash mark. With the assist, Backlund extended his five-game point streak to eight points (four goals, four assists).
"'Backs' has been making a lot of really good plays lately and putting pucks on my stick, and (I) just wanted to get it off quick and it found a hole,” Coleman said. “It was going to be hard to score tonight, so getting one was good."
