Claude Giroux scored twice for the Senators (14-23-0). Anton Forsberg allowed one goal on seven shots before leaving at 11:56 of the first period with a right groin injury. Joonas Korpisalo made 21 saves in relief.
“We’ll get a little more news tomorrow,” Ottawa coach Jacques Martin said of Forsberg. “I think he’ll get an MRI tomorrow and we’ll find out more on his condition.”
JJ Peterka gave the Sabres a 1-0 lead at 9:14 of the first period. Cozens skated the puck around defenseman Erik Brannstrom in the right circle and sent a pass through the slot to Peterka, who scored from below the left circle. It was Peterka’s first goal since Dec. 11, ending a 12-game drought.
“Obviously he’s been on a little bit of a stretch here without a goal, and I’ve kind of struggled offensively too,” Cozens said. “So, to get that one early, it was a big for our line’s confidence moving forward. And I think we’ve had lots of chances as of late, but we haven’t put one in the back of the net, so to get one there felt good for us.”
Vladimir Tarasenko tied it 1-1 at 15:06, picking up Sabres forward Casey Mittelstadt's clearing attempt and beating a screened Luukkonen with a wrist shot from the point.
Thompson put Buffalo ahead 2-1 at 17:28, skating end-to-end and beating Korpisalo with a wrist shot from the slot.
Thompson made it 3-1 just 2:04 later with a wrist shot from the left circle on the power play at 19:32.
“You can see when he has that confidence, he’s just making guys look silly out there and he’s shooting the puck with authority,” Cozens said of Thompson. “Those two goals were pretty hard shots. So, that’s the Tage we all know and love, and hopefully we see a lot more of that the second half of the year.”
