Sam Bennett gave the Panthers a 4-3 lead at 6:19 of the third period. After Tkachuk’s shot from the left boards bounced off Varlamov’s stick, it deflected in off Bennett’s leg in the crease.
Tkachuk then scored his second of the game to make it 5-3 at 9:49. He beat Varlamov with a wrist shot from the top of the right circle on the power play.
Gustav Forsling scored a short-handed empty-net goal from deep in his own zone at 17:43 for the 6-3 final.
“We have to address [the blown leads] as a group,” Islanders forward Casey Cizikas said. “That's something that starts in here and it starts with, first off, a conversation, and going over where those mistakes are and what we can do better. But it's something that we’ve got to figure out.”
Dennis Cholowski gave the Islanders a 1-0 lead at 1:32 of the first period when his wrist shot from the left point beat Knight blocker side through a screen. It was Cholowski’s first goal since April 24, 2021, with the Detroit Red Wings.
Palmieri pushed the lead to 2-0 at 6:01, scoring five-hole by poking in the rebound of his own deflection at the right post.
Brock Nelson made it 3-0 at 11:41. Tsyplakov’s wrist shot from the slot missed the net and caromed off the end boards to Nelson at the right post, where he banked the puck in off Knight.
