Tkachuk tied it 3-3 on the power play with his 37th goal at 47 seconds of the third period, taking a pass down low and finishing with a backhand to the glove side.
Newhook put Montreal back in front 4-3 at 15:49 when his centering pass went in off Ottawa defenseman Jakob Chychrun’s skate in the crease.
“Another tight one,” Newhook said of the result. “I think we’re finding ways to stay in games, stay there at the end, but just a little bit of execution, giving them a 6-on-5 goal. It happens. I think some of those smaller details are what it comes down to when you’re not on the right side of these close games. Just stuff I think we can tidy up here moving into next year.”
It was likely Martin’s final home game as Ottawa coach, as the Senators will search for a permanent replacement during the offseason. The 71-year-old, who replaced D.J. Smith on Dec. 18, also coached the Senators from 1996-2004 and holds franchise records for games coached (746) and wins (366).
“It’s been great,” Martin said. “I enjoyed the opportunity to come back and hopefully help the team understand what it takes to be in the playoffs, how you need to play on a nightly basis, help the players grow and maybe get better. As an organization I think we have some work to do, but I think we’re in the right direction.”
