Aleksander Barkov ended last season by hoisting the Stanley Cup, as the Florida Panthers fans got to roar in delight. And this season started the same way.

Barkov, the Panthers’ captain, skated the Cup onto the ice Tuesday night moments before Florida hoisted its first championship banner to the rafters — with players all arm-in-arm as they gazed at the building’s newest memento.

The Panthers posed with the Cup one more time after the banner made its 2-minute trip skyward, and then, finally, it was time for a new season to begin with a season-opener against the Boston Bruins.

“Now we get to try to chase it again,” Barkov said.

That chase started with a 6-4 win.

Sam Bennett scored twice, Sam Reinhart and Evan Rodrigues each had a goal and an assist to pace Florida.

Euto Luostarinen and Jonah Gadjovich also scored for Florida, while Sergei Bobrovsky stopped 24 shots.

Florida is 4-1 in its last five openers.

Pavel Zacha, Charlie McAvoy, Trent Frederic and David Pastrnak scored for Boston, which had won five consecutive openers.

The Panthers played Game 7 of the Stanley Cup Final against the Edmonton Oilers on the giant video screens over the ice before warmups, fans cheering again when Reinhart scored the go-ahead goal and getting even louder when the final seconds where shown. And then came the real ovation — when the final part of the Cup celebration came and the banner took its place in the rafters.

The pregame ceremony capped 3 1/2 months of reveling in the franchise’s first title.

“The fans will really enjoy the banner,” said Panthers forward Carter Verhaeghe. “Looking up there, I guess if you need a little inspiration, you just look up there and see what we accomplished.”

Blues 3, Kraken 2 >> Jordan Kyrou scored two goals less than two minutes apart late in the second period, and St. Louis rallied from an early two-goal deficit to beat Seattle in a season opener.

Philip Broberg also scored for St. Louis, his goal sandwiched between the two by Kyrou. All three goals came in a span of 1 minute, 55 seconds.

Vince Dunn and Eeli Tolvanen scored two minutes apart early in the second period for the Kraken.

Before the game, Seattle selected Jordan Eberle as its captain, filling the last void at that spot among the NHL’s 32 teams. Every team in the league has a captain for the first time since the 2010-11 season.
