"The guys made it easy for me, very simple," Petersen said. "Not a lot of odd-man rushes, if any. Just had to make the saves I needed to make, and the guys did a great job. So, a lot of credit goes to them.”
Prior to Saturday, Petersen played one game since his start in November, making 19 saves on 21 shots in relief of Samuel Ersson in the Flyers' 6-2 loss to the Boston Bruins on Jan. 27.
Since winning 20 games with the Los Angeles Kings in 2021-22, Petersen has played more games in the American Hockey League (55) than the NHL (14).
"It's been a challenging couple of years, but I think it's made me a lot stronger," Petersen said. "I've got a lot more of a passion and commitment to my craft. And I think that's just enjoying every opportunity that I get, enjoying the people around me, enjoying getting better every day."
Scott Laughton, Ryan Poehling and Sean Couturier scored for Philadelphia (28-19-6).
Tomas Tatar and Jared McCann scored for Seattle (21-20-10), which lost its fifth straight on the road. Joey Daccord made 35 saves.
It was the Kraken's first game since Jan. 30.
"There were more plays to be completed, to be had, especially in the first half of the hockey game," Seattle coach Dave Hakstol said. "Little bit off in execution, and that changes the number of opportunities we were able to gain. Their team, they skate, they pressure, they stay on top, we know that. If you can make one extra play, you get opportunities. We got some of those, but not enough, and we didn't have enough of those clean opportunities in this game."
