"I'll take the points," Brunette smiled. "I think I aged again tonight a little bit, but always take the win."
Finding the back of the net for the third straight game, Aleksander Barkov opened the scoring against the Capitals. With Anthony Duclair poking a loose puck to the captain, Barkov then ripped a shot from the slot right past Ilya Samsonov and into the twine to put the Panthers up 1-0 at 3:07 of the first period.
Washington challenged for goaltender interference, but the goal was upheld after a review.
Doubling the lead later in the period, Aaron Ekblad, who has made a dent on the scoresheet in eight of 10 games this season, blasted a shot through traffic to increase Florida's early advantage to 2-0 at 11:04.
Exiting the game due to an upper-body injury, Sergei Bobrovsky was replaced by Spencer Knight in net for the Panthers at the start of the second period. Testing the rookie right away, Daniel Sprong scored on a breakaway to quickly slice Washington's deficit down to 2-1 just 43 seconds into the middle frame.
After the game, Brunette said Bobrovsky is day-to-day and will be revaluated on Friday.
Getting that goal back for the Panthers, Brandon Montour took a pass from Gustav Forsling, who leads the team's defensemen in assists this season with nine, and fired a high-rising shot from the point that sailed right over Samsonov's blocker and into the top corner of the cage to make it a 3-1 game at 7:16.
After that goal, Vitek Vanecek came into the game in relief of Samsonov.
With the Panthers on the power play, Barkov continued to climb the record books when he tapped a juicy rebound past Vanecek to make it a 4-1 game at 15:32. The 188th goal of his career, the 26-year-old is now locked in a tie with former Panthers captain Olli Jokinen for the most goals in franchise history.
"It feels great," Barkov said. "I know [Jokinen] was a legend here. He was a great, great player and played here a long time. I'm really proud that I get to be on that same level with him in that category."
As the period neared its end, the Capitals went on the attack.
Scoring twice within less than two minutes, Alex Ovechkin and Tom Wilson found the back of the net at 18:11 and 19:43, respectively, to reduce Washington's deficit to 4-3 going into the second intermission.
Tying things up, Connor McMichael then scored just 6:56 into the third period to make it 4-4.
"I think it was a back-and-forth game," Brunette said of the momentum swing. "It was one of those games where you never felt overly comfortable. They put you in uncomfortable positions. They're very structured, come at you in different waves and put pressure on you. It never really felt comfortable. We did some good things, and then some things that we'd like to have back. It was one of those games."
Once the game eventually got to overtime, the Panthers applied tons of pressure on the Capitals -- including a clutch takeaway from Barkov -- to keep them forcibly pinned them in their zone. After holding Washington without a shot in the extra frame, Luostarinen then lit the lamp at 1:55 when his pass to Frank Vatrano was tipped into the net by Tom Wilson to secure the 5-4 win for the Panthers.
On Saturday, the Cats will look to keep rolling when they host the undefeated Hurricanes.
"At the end of the day, it's all about winning games," Barkov said confidently. "You're not going to have your best night every night. We've played some really good hockey at the beginning of the season."
