Granlund gave the Predators a 2-1 lead at 1:13 of the second period, scoring off a backhand pass from the point by Ryan Ellis.
Ryan Johansen extended the lead to 3-1 at 7:32 on a redirection of a pass from Josi on a 5-on-3 power play.
Aho cut it to 3-2 at 13:34 on a redirection of a shot by Hamilton on the power play.
"They turned it up, for sure," Johansen said. "But I think it was probably a little more on us and how we sat back and didn't have enough poise and continue to make plays and have the pace we were having there in the second period, especially. That's what we wanted to get back to in overtime, and obviously they scored early. They're a great hockey team, they did some good things in the third to tie it up and win it in OT."
