Ottawa took advantage of the referee's generosity, and to add insult to injury, it was Ryan who ended up finishing it off when he redirected home a pass from Turris past Rask to give the Senators the unlikely 4-3 win and 2-1 series lead.
In the second period, down 1-0, Ottawa was on the power play when MacArthur got a Bobby Ryan pass right in front. Craig Anderson finished with 17 saves.
"That's the way it goes in the playoffs, the tide changes, there's a lot resiliency in the playoffs", said coach Guy Boucher.
If the Ottawa Senators show the same intensity and passion they did in the third period of Game 2, they will leave TD garden with a 2-1 series lead.
Noel Acciari and David Backes also scored for the Bruins.
Overall, the Bruins need to allow goalie Tuukka Rask to see the puck better moving forward.
The fun got started for the B's in the second, but not before the crowd was silenced almost four minutes into the period. We have to step up and all be better. Bruins forward Riley Nash was serving a roughing penalty at the time after he got mixed up with Ryan. "If you told us it was going to be a tie game going into the third, we would have taken that any day of the week if you told us that going into the game".
Ottawa seemed to be cruising in the second period following Hoffman's second goal of the night off a power play to make it 3-0. That goal for Boston came at the end of a short 5-on-3 after the Senators took back-to-back penalties.
Then, 42 seconds later, Ryan couldn't handle the puck in the own zone.
Then, the Bruins finally cashed in on Pastrnak's goal with Dion Phaeneuf in the penalty box for slashing. A concussion has kept the Senators left wing out of the Ottawa line up sine October 2015 and many thought he'd never play again.
Acciari and center David Krejci both returned, but Boston struggled early to find much offensive traction.
Defenceman Marc Methot isn't letting the Ottawa Senators' Game 2 win against the Boston Bruins get to his head. After going 13 regular-season games without a goal, Ryan has scored twice in Ottawa's three playoff games. Braden Holtby made 48 saves for top-seed Washington, which is feeling the heat with Game 3 Monday in Toronto. We (will) get this thing tied 2-2 and make it a two-out-of-three series.
Alex Ovechkin, Nicklas Backstrom and Evgeny Kuznetsov all scored for the Presidents' Trophy-winning Capitals. He's had five hits, three blocked shots and played 24:11 and 27:47, respectively. In other words, every game has been a battle, and Game 4 should be no different.
"We still have a long way to go here and a couple more games in Boston". In their Game 2 loss to the Ottawa Senators, Chara was on the ice for more than half an hour. He stopped the initial shot, but Matthews hung with it and batted the rebound out of the air to cut the deficit to 2-1.
Yet through two games of their first round playoff series against Nashville, the 'Hawks have failed to score a single goal.
They may, but probably won't, have rookie Brandon Carlo back in the lineup. It got the crowd right back into this one, towels-a-waving, chanting "Let's Go Sens!"
"The second period we didn't really come out the way that we wanted and we needed a response and I think that we definitely gave them that in the third", Karlsson said.
