"We just weren't clean," Panthers interim head coach Andrew Brunette said. "It wasn't out of a lack of effort. We just weren't sharp. There's going to be nights like that. It's unfortunate that it comes at home at a time when you could've done something pretty cool, but that's hockey."
Still sitting atop the Atlantic Division with 14-4-3 record, the Panthers will now have to settle for being tied with the 1963-64 Blackhawks for the best start on home ice in NHL history at 11-0-0.
"We all knew what was at stake tonight, but it's behind us now," Panthers forward Owen Tippett said of the team's stellar streak coming to an end. "We have to look forward to the next game."
Despite their 7-13-1 record, it was clear from the start that Seattle was going to put up a fight.
Not long after Chris Driedger denied Jonathan Huberdeau on a shorthanded breakaway, the Kraken opened the scoring when Jordan Eberle collected a pass in the slot on the power play and unloaded a one-timer into the twine from the slot to make it 1-0 at 2:22 of the first period.
Tying up the game with a timely tip, Patric Hornqvist then got the Panthers on the board and made it 1-1 when he re-directed a slap shot from MacKenzie Weegar into the cage at 6:59.
Scoring in a similar fashion less than five minutes later, the Kraken retook the lead when Ryan Donato deflected a point shot from Jamie Oleksiak past Spencer Knight to make it 2-1 at 10:40.
In the second period neither team found the back of the net, but the Panthers looked to be in control for the majority of the 20 minutes. Leading 13-7 in shots on goal in the period, Florida also owned advantages in shot attempts (21-14) and scoring chances (13-7) in all situations.
"I think when you get chances and they don't go your way, frustration builds up," Tippett said. "You've got to find a way to put that aside in games like that and keep working shift after shift."
Despite that push, the Panthers fell behind further in the third period when, after Yanni Gourde forced a turnover in the offensive zone and fired a shot on net, Eberle buried a backhand shot on the rebound for his second goal of the night to increase Seattle's advantage to 3-1 at 5:57.
With the Panthers pulling their goaltender in favor of the extra attacker as they attempted to spark a comeback later in the period, Oleksiak provided the dagger for the Kraken when he fired a puck down the ice and cashed in on the empty net to make it 4-1 with 3:25 left in regulation.
Knight finished with 23 saves, while Dreidger made 33 to earn his first win with Seattle.
"We've seen it before," Brunette said of Driedger, who spent two seasons in South Florida before being claimed by the Kraken in the Expansion Draft. "He's made some big saves. We really didn't get enough puck traffic around the net or inside, so we made it a little bit easier on him. But he made some great saves. He played great for us last year, so it's not surprising."
Looking to start a new winning streak, the Panthers will host the Capitals on Tuesday.
