"I'm most impressed with his poise in all senses, not just on the ice," Kraken coach Dave Hakstol said. "On the ice, his hockey sense and his ability to know and understand what's around him on the ice showed to be excellent tonight. He looked comfortable in traffic. That's a big challenge on night No. 1. I'm sure he's as disappointed as everybody is in not being able to get the win tonight, but he played a good hockey game on night No. 1."
Tkachuk tied it 1-1 at 16:51 when he tipped Hanifin's wrist shot from the point.
Victor Rask made it 2-1 at 3:06 of the second period when he one-timed a pass from Yanni Gourde from behind the net and Adam Larsson extended the lead to 3-1 at 17:10 with a shot along the ice.
"I'm pretty happy with the way we fought back there in the third," Gaudreau said. "We haven't had too many comeback wins this year, so it's nice to get that one. Obviously, it was a big one for us."
