Eklund put the Sharks ahead 1-0 at 2:13 of the second period, beating Korpisalo five-hole after a pass from Celebrini from along the right boards.
"We were actually talking on the bench," Celebrini said. "Eklund said something about going five-hole on him, and then he went five-hole on him."
Mittelstadt tied the game 1-1 at 16:50. After Georgiev moved the puck to Vincent Desharnais, Cole Koepke took the puck away and fed Mittelstadt in front before Georgiev could get back to the crease.
"There was a stretch where I thought we could've played better, but we had them on their heels," Mittelstadt said.
