Sorensen provided a hero's play late in the Panthers' win over the Tigers on Sunday, rushing from the other side of the field to stop Jahream Bula inches from the line.
Prop Lindsay Smith then provided a similar effort on the next set, getting back to help deny Bula again with the Panthers leading 18-14.
The Panthers' win meant they finished the round in 13th spot but just one point out of the top eight, after a horror start to the season had them sitting last after 12 rounds.
Penrith players saw similarities between Sorensen's effort, and Viliame Kikau's famed effort to hold Melbourne's Justin Olam up after the siren in the Panthers' 2021 grand-final rematch.
Kikau's desperate play has for years helped Penrith set the standards for success, and teammates believe Sorensen's effort on Sunday can have a similar effect.
"We'll look back on that as a pretty defining moment. It was huge," fellow second-rower Liam Martin told AAP.
"I remember the (Kikau) one, where he slid and held (Olam) up over the line.
"It's just those little plays that you just value ... They're just little plays that probably not a lot of people notice, but they get so valued in our team.
"It gives you so much confidence when you see stuff like that happening, your teammates doing that, and you just build energy off it."
Penrith face a tough run ahead to keep their season revival on track, with a trip to Auckland without State of Origin players after the bye.
They then face Canterbury off a five-day turnaround, before having the Bulldogs again, Melbourne and Canberra on their run home.
Martin admitted the Panthers may have lacked that kind of desperation in their game as they went 2-6 to start the season, a point Nathan Cleary agreed with.
"That's probably been the difference between winning and losing games," Cleary, who was involved in both tackles on Bula with Sorensen and Smith, said.
"At the start of the year we weren't doing that at all and it was biting us in the butt a fair bit.
"That's what we want our DNA and identity to be like. And we definitely applaud plays like that.
"Then it starts to become something that happens just by DNA ... there were even a few of those last week (against Parramatta) as well."
Sorensen, for his part, dodged the praise after Sunday's win.
"It's no different to anyone else in this team," he said.
"It's just doing your job, and tonight was my time to do my job. It's as simple as that."
