Keller tied the game 2-2 at 15:57, tapping in a rebound off a shot from Schmaltz.
“We had a good [third period],” Keller said. “I think for whatever reason, our second hasn't been great, but we've been able to bounce back and play hard in the third, get back to our style of hockey, and I think we did a great job of that tonight.”
Guenther gave the Mammoth a 3-2 lead at 10:37 of the third period. JJ Peterka stole the puck from Khusnutdinov before sending a pass to Guenther in the left face-off circle, who then beat Korpisalo with a one-timer.
“That's when you want to play, when the game's tied, when you're at home, and the crowd's into it,” Guenther said. “They're a heavy team and they kind of want to slow it down and we’re more fast-paced and try to speed it up. I thought that we adapted well and we were able to get pucks in, get pucks out.”
