Nick Cousins regained the lead for Ottawa, 2-1, at 1:50 of the second period. Off the rush, Cousins attempted to pass across to Michael Amadio, but the puck deflected off defenseman Samuel Girard and back to Cousins, who tapped it in on the backhand.
Karlsson tied it 2-2 at 3:45, connecting again with Rakell for a goal from the left face-off circle.
Rakell’s power-play goal gave the Penguins a 3-2 lead at 1:43 of the third period, their first of the night. Karlsson fed Rakell at the left dot during a 5-on-3 for his third goal in his past two games.
“We’re trying to have more fun with it, even though it’s a lot on the line,” Rakell said. “You just got to be patient when you take shots; it’s a 1-on-1 when you score.”
Batherson’s second goal of the game tied it 3-3 at 3:58 after collecting a netfront rebound from a Stutzle shot following the face-off. The Penguins challenged for goaltender interference, but the call on the ice was upheld following video review.
“I saw (Claude Giroux) was in the blue paint, there’s contact there,” Muse said. “I felt like it affected Stu’s ability to play it with the way that he spins, he gets his stick, that impacts the goalie’s ability to make the save.”
Both sides made multiple big saves in overtime, including Ullmark robbing Tommy Novak on the breakaway with under 20 seconds to go.
“I think Linus got us that point tonight,” Tkachuk said. “He played unreal tonight, made some huge saves at the right time. We got the point because of him.”
NOTES: Stutzle became the fourth German player in NHL history to reach 400 career points, joining Leon Draisaitl (1,053), Marco Sturm (487) and Jochen Hecht (463). He also became the seventh player to reach the 400-point milestone with the Senators. Stutzle required the third-fewest games among the group to hit the mark (439 games), behind only Jason Spezza (388) and Alexei Yashin (417). … Karlsson collected his 714th career assist and surpassed Daniel Alfredsson (713) for the fifth most by a Swedish player in NHL history. … Karlsson has recorded three or more points in each of his past three road games. The only defensemen with a similar streak in NHL history are Bobby Orr (4 games in 1970-71 and three in 1973-74), Kris Letang (three in 2023-24), Roman Josi (three in 2021-22), Phil Housley (three in 1992-93), Borje Salming (three in 1984-85) and Paul Coffey (three in 1983-84).
