Mikhail Sergachev scored from the left point through traffic at 9:01 to give the Lightning a 2-1 lead. It was Sergachev’s first goal of the season.
The Blackhawks took advantage of a turnover to tie the game at 2:09 of the third period. Perry picked up the puck, skated into the offensive zone and scored from the side of the net after return passes from Boris Katchouk and Jason Dickinson.
Hedman, a defenseman, found himself in the unfamiliar position of being in front of the net when he scored the go-ahead goal.
“Yeah, it’s easy to be a forward,” he said. “You get pucks in the crease like that. No, that was huge.”
The Blackhawks had a season-low 15 shots on goal, and only two in the third period.
“Yeah, but at the same time, I think we passed up a lot of shots,” Perry said. “Especially in that second period, we had some good shifts and we tried to maybe be a little too cute where some of those pucks have to get on net.
“They're a good team. When they get the lead, they kind of sit on it and play strong and there's not much room out there. Those are learning curves that we can build along the way.”
NOTES: Lightning forward Anthony Cirelli left the game after he blocked a shot by Blackhawks defenseman Wyatt Kaiser at 1:26 of the second period. Cooper said he was unsure of Cirelli’s status. “He’s a tough kid,” Cooper said. “The fact he couldn’t come back is a little worrisome.” … Hedman scored his 147th NHL goal to tie Fredrik Olausson for fourth on the NHL’s all-time list among Swedish defensemen. He trails Nicklas Lidstrom (264), Erik Karlsson (183) and Borje Salming (150).
