"Every game's kind of different," Binnington said. "Tonight it felt like we got that two-goal lead, I think we would've liked to press a little harder, keep the foot on the gas. Going into the third period, 2-1 hockey game, they don't score another one and we win the game. That's kind of the mindset, and it worked out."
Noel Acciari and Jake Neighbours scored for the Blues (22-20-3), who lost their previous two games and are 2-2-0 on a season-long seven-game homestand.
"Yeah, they work," St. Louis coach Craig Berube said of the Senators. "They play hard, they've got some good skill, some high-end players that are still young. They've got a lot of good players and they're a hard-working team.
"I think we did a good job. There were some shots in the third period that we gave up that we should have had covered, and we didn't. That's one area that's got to be better. Overall, I think we did a pretty good job."
Tim Stutzle
scored, and Cam Talbot made 18 saves for the Senators (19-21-3), who have lost four of five after winning four of five.
"I think we played pretty well," Stutzle said. "I think we could have deserved to win tonight, but in the end, that's how it goes sometimes. I felt like we stuck with it. We played really good in the third as well, had so many opportunities to score. But in the end, if we keep playing the right way, I think there will be a lot of wins."
