“With all the ice, I told myself I better score,” said Tkachuk, who added an assist for a three-point night.
“It was a good effort by our team,” Tkachuk said. “That’s a good team and now we’ve had good efforts against two top teams. We’ve put in some great efforts, but I believe that we have more.
“I thought we played a responsible game and did a lot of stuff right.”
Jost scored 1:52 into the third period to pull the Avalanche within 5-4.
The Avs looked to have tied the game in the final three minutes, but a challenge by the Senators showed the play was offside.
Toews then scored on a point shot at 18:40 to send the game to overtime.
The Senators went into the third period with a 5-3 lead thanks in part to two second-period goals by Stutzle.
Tied 2-2, Stutzle gave the Senators a 3-2 lead after he was pushed into Johansson by Jack Johnson while on a partial break. All three ended up in the net, as did the puck, but only after the net was dislodged. After a lengthy review, the goal stood just 1:13 into the period.
“I think it was the luckiest goal I ever scored,” Stutzle said.
“Everybody thought it was going to be a good goal so everyone was pumped. For me, it was great after kind of a rough start with the goals, but Brady’s overtime goal was way more important.”
Senators coach D.J. Smith had little doubt that the goal was going to count.
“I saw (John) Tavares had the same goal in Toronto about a month ago and it counted, so I was confident it was going to count,” Smith said.
“We did a lot of things and obviously we’ve got to find a way to keep those pucks out at the end. Good teams can clamp down and we gave up a couple at the end.”
Norris gave the Senators a 4-2 lead at 2:49 and knocked Johansson from the game. Annunen came on and gave up a power-play goal to Stutzle at 7:46.
“I didn’t like the way we played in the first half of the game,” Avalanche coach Jared Bednar said. “We didn’t manage the puck very well. Both goal one and goal two against, they’re both turnovers, one in the neutral zone, one in the (offensive) zone.
“We talked about how dangerous Ottawa is off the rush, they’ve got some get-up-and-go and they can make plays off the rush. And if we were able to take that away from them, then our chances of success go up greatly. We didn’t do that tonight.”
Then came the prettiest goal of the night as Newhook stepped around Lassi Thomson, went in alone and beat Forsberg on the short side, cutting Ottawa’s lead to 5-3 just shy of the halfway mark in the game.
The teams combined for four goals in the opening 10 minutes of the second period, but they also combined for four goals just over eight minutes into the first.
Helm gave the Avalanche a 1-0 lead 1:26 into the game. The Senators replied with goals from Tkachuk and Watson 29 seconds apart about four minutes later. Watson’s goal was his first of the season.
Landeskog tied the game when he tipped a shot by Toews from the point past Forsberg at 8:19, just seven seconds into a power play. Landeskog extended his point streak to seven games.
Avalanche: At Philadelphia on Monday in the fourth of a five-game trip.
