Blore made his first grade debut in round 11 of the 2020 NRL season for Wests Tigers against the Parramatta Eels at Bankwest Stadium where Wests lost the match 26–16.[3][4]
He was said to have "stood his ground in a fiery head-to-head and came away with a points decision" against Parramatta's Nathan Brown.[5] After the match, coach Michael Maguire said, "I don't think he's played a full game of footy for about 14 months now, to see him play the way he did it was welcome to first grade that's for sure. He played a lot of time too, I didn't expect him to play that much time but he hung strong and showed he can play at this level."[5] He made 5 appearances from the bench during the season, all losses.
