The host Ottawa Senators are surging, while the Detroit Red Wings are slumping ahead of their pivotal matchup on Monday night.The Senators, who entered Sunday leading the Eastern Conference wild-card race, have won three of their last four (3-0-1) after Saturday’s 4-3 come-from-behind home overtime win over the New York Rangers.Meanwhile, the Red Wings have lost five in a row following Friday night’s 5-2 road defeat against the Washington Capitals, leaving them three points behind the Senators and two points out of the second wild-card spot entering Sunday.In Ottawa’s second consecutive 4-3 overtime win, the team rallied from a 3-1 third-period deficit, with captain Brady Tkachuk’s second goal of the game 33 seconds into the extra session completing the comeback.Tkachuk stretched his goal-scoring streak to five and has a team-leading 26 in 60 games. Tim Stutzle is first in assists (45) and points (65) in 62 games for Ottawa.”You look at some of the chances that we missed, power-play opportunities that we didn’t capitalize on (Ottawa was 0-for-5 with the man advantage),” Tkachuk said. “Yeah, we could’ve easily let the frustration consume us, change the way we want to play and get in the way of what we’re trying to do. I think that’s just showing where our team is at right now. Frustration doesn’t matter; it’s always the next shift.”Ridly Greig (9:44 remaining) and Michael Amadio (2:52 remaining) scored in the third period for the Senators. Linus Ullmark stopped 20 shots.”It’s been an emotional 24 hours for not only him but the rest of our group (after trading forward Josh Norris and defenseman Jacob Bernard-Docker to Buffalo on Friday),” Ottawa coach Travis Green said. “And having a 12:30 p.m. start, I give our team a lot of credit for getting focused to play (today). The guy’s the captain of our team. He’s maturing a lot as he goes along, as well.”Dylan Cozens, who was acquired in the deal from the Sabres, assisted on Greig’s goal.
