"That was the momentum swing right there," Lightning forward Ryan Callahan said. "Killing off the penalties was big, and then to grab two like that deflates the other team and lifts us up."
Kapanen gave the Maple Leafs a 1-0 lead at 5:26 of the first period when he scored unassisted off a turnover by Kucherov.
"It was a great team that we just played against, but other than the little collapse in the second period, we were on top of them," Kapanen said. "[Vasilevskiy] is a big guy, he covers a lot of the net, and he made those big saves."
