This time however, it's in enemy territory, the Ottawa Senators head to Boston.
"Demoralizing and disappointing. there's probably a lot more words, but they called it", Bruins interim coach Bruce Cassidy said of referee Tim Peel's call that produced an overtime power play.
"I think it was pretty selfish of me", he said.
A controversial penalty call on Riley Nash that sent him to the box for two minutes for roughing and that would make all the difference. In this case, the officials penalized the retaliation.
With the power play winding down, Ottawa's Kyle Turris slid a pass to Bobby Ryan for a tap in goal to give the Senators the walk-off win. While they've outshot the Bruins, and are almost equal in shot attempts, many of those shots have come outside the home plate area (widely considered to be the danger zone), which isn't good enough when facing a goalie of Rask's calibre.
The assist was the second of the game for Karlsson.
Noel Acciari and David Backes also scored for the Bruins. I think that's just playoff hockey, but it's just one of those things that, a dirty play here, a dirty play there...it doesn't matter.
As the Senators were leaving the ice following the win, which was aided by a controversial penalty call in OT, there was some bitterness and anger from Boston fans surrounding the Ottawa tunnel. At the outset of the first playoff game since the Presidents' Trophy-winning Bruins of 2013-14 were upset in a Game 7 by the Montreal Canadiens, the Garden was rocking. Fans showed their displeasure by littering the ice with debris, including bottles filled with liquids. The Bruins will be hoping that he can translate that experience to play a responsible game in the National Hockey League; he doesn't need to do more than that to help the team Monday. "You know, they take it to us and get some good looks, and we didn't respond..." Thirty-five seconds later, Derick Brassard pumped home a loose puck from close range to make it 2-0.
After pulling out to the 3-0 lead early in the second, the Bruins came charging back to erase the deficit and Pastrnak tied it up on the power play with 6:09 left in the second on a shot that beat Anderson stick side.
While on the power play, David Pastrnak wired home a shot to the short side of the net that tied the score at 3-3.
Craig Anderson made 26 saves for Ottawa and Tuukka Rask had 25 saves in the Boston net.
It all started with an alley-oop pass from Erik Karlsson to Mike Hoffman.
Shea Theodore had two goals, Nate Thompson had a goal and two assists, and Nick Ritchie also scored for the Ducks. Boston registered only one shot on goal over the final 16:18 of the first period.
Backes scooped up the loose puck and broke in all alone on Anderson to score and cut the Ottawa lead to 3-2. But Boucher was quick to say both victories are in the past. Krejci has plenty of postseason experience (93 games), and has fared quite well, recording 29 goals and 77 points in the playoffs.
Providence Bruins captain Tommy Cross, who was called up Monday on an emergency basis, made his Stanley Cup playoff debut on the third defensive pairing.
The Bruins were already down to their ninth defenseman on the depth chart as Joe Morrow was in for an injured Colin Miller.
