Cole Reinhardt scored 1:25 later to extend it to 2-0 at 6:34. Braeden Bowman found Reinhardt, who went backhand to forehand in front of Lankinen on the rush and finished at the far post.
Pettersson cut it to 2-1 at 7:11 after scoring on the rush, but Barbashev responded 28 seconds later to make it 3-1, roofing a wrist shot from the slot off a drop pass from Stone.
“Any time the other team scores, you want to have a response,” Eichel said. “It’s good to find a way to get the goal back after you give one up.”
Joseph cut it to 3-2 at 19:51 with a wrist shot from the left point. It was his first goal since April 4, 2024.
“There are a lot of good things that we did tonight,” Joseph said. “We’ve got to focus on the little details that make us slip into games like that. There are a lot of positives. So, we need to get into the (Olympic) break and get into a good mindset.”
Dorofeyev extended it to 4-2 at 2:31 of the third period after Mitch Marner won a puck battle near the side boards and found Dorofeyev at the far post for an easy tap-in.
