World number eight Aspinall has confounded critics who opposed his inclusion in the eight-man competition, having been ranked 11 when the picks were made.
His inclusion was questioned by fellow players Mike de Decker and Dave Chisnall amid suggestions his popular walk-on song Mr Brightside helped his case.
The Stockport-born player has faced online abuse over his participation, as well as recovering from injuries and dartitis to reach the final four.
“I came off social media because of the abuse I was getting,” said ‘The Asp’ after his second nightly win, in Aberdeen a week ago.
“I’m not being exaggerated here, but it ruined my life for a month, not just my life, my family’s. It was horrific. “
Aspinall has also come back from elbow, wrist and back injuries, along with tackling dartitis – a condition where players have a mental block when it comes to throwing on the stage.
Missing out on qualification completes a miserable campaign for Van Gerwen, whose last nightly win came back in April 2024.
The three-time world champion had seven victories and two runner-up spots from his previous 12 campaigns, with his last Premier League title in 2023.
“This is probably one of the hardest Premier Leagues I have ever played in – not in terms of players, but in terms of myself,” Van Gerwen admitted.
His cause was not helped when missing the ninth event of the season in Berlin with a shoulder injury sustained while trying to put a shirt on.
Humphries reached the semi-finals in Sheffield with a 6-4 win over Rob Cross before a 6-2 defeat of Chris Dobey, who earlier came from 4-0 down to beat Price 6-5.
