Kucherov pushed it to 4-0 at 4:42 of the second period. Gourde faked a shot from the slot and found him open at the bottom of the right circle for a shot into the open net.
"We took care of the things that we could control and it was a good game," Gourde said. "We have to continue to play to our system, do the small little things, play to our strengths, keep building on that mentality and working on those details."
Marchand made it 4-1 at 5:36 when he finished a 2-on-1 rush with a wrist shot that beat Vasilevskiy low glove side. It was his second goal with Florida since being acquired from the Boston Bruins on March 7.
"We were a little slow and we were a little off on the forecheck," Panthers forward Eetu Luostarinen said. "But we'll skate a couple of days and rest before [the playoffs]."
Darren Raddysh scored a power-play goal, on a one-timer from the left circle off a cross-ice pass from Kucherov, at 11:22 of the third period for the 5-1 final.
"There were a lot of question marks about what this team was going to look like after we lost a cornerstone of our organization," Cooper said in reference to longtime forward Steven Stamkos signing with the Nashville Predators last offseason. "I think there was a lot of uncertainty about how things were going to play out. If you look back from then to now, we've got 100-plus points. Not only did we make the playoffs, but we found a way to get home ice."
NOTES: Kucherov leads the NHL with 121 points (37 goals, 84 assists). He reached 120 points for the third time in his career (144 in 2023-24 and 128 in 2018-19). ... Hedman reached the 50-assist mark for the fourth time in his career. ... Verhaeghe, who had an assist, has six points (three goals, three assists) during a five-game streak. ... Panthers forward Jesse Puljujarvi received a match penalty for a check to the head against Lightning forward Mitchell Chaffee. "That's an unfortunate situation," Cooper said.
