The 22-year-old Storm fullback finished the game with over 200 metres from his 19 carries, including a long-range try.
“This is unbelievable, I’m pretty speechless and emotional,” Papenhuyzen said during his acceptance speech for the prestigious award.
“Thanks to the boys, we didn’t know where we were going all year.
“It’s been a great year playing with these boys and thanks to Penrith, 17 wins in a row is a great achievement.
“It’s a tough time in Victoria at the moment and we wear the V with pride.”
