Brisbane Lions' forward Sabrina Frederick-Traub and Melbourne Demons' defender Jasmine Grierson are the round four nominees for the AFLW Rising Star award.

Grierson was an integral part of the Demons win over the Blues over the weekend, the 18-year-old was in the middle of a University lecture when she received the news on Monday evening.

"It's pretty surreal. Our manager Debbie Lee called, but I was at my first day of ‘uni’… I called her back and she broke it to me. She was very excited, I was very shocked," she said.

Grierson played only a few senior matches for Cranbourne in the VFL Women's competition last season. She has been steadily improving over the course of the season for Melbourne, resulting in a 16-disposal, five-mark game against the Blues on Saturday.

Grierson said her move down back has been the catalyst for her improvement.

"I feel like I can make more of an impact (in defence) because I can use my run and pace off half-back and use my skills a bit more," Grierson said.
