Jonny Clayton produced a flawless display to claim the last semi-final spot on the PDC Home Tour.
The world number 15 won all three of his games in Group Eight of the last-32 stage to progress to the Thursday's semi-final group, where he'll meet Nathan Aspinall, Joe Cullen and Rob Cross.
The Welshman averaged over 100 in 6-3 wins over Scott Waites and Max Hopp, then saw off Carl Wilkinson 6-2.
"A win is a win," said Clayton. "Obviously I'm happy to win three games. I'm a happy man."
Waites had kept the pressure on Clayton throughout the evening by following his narrow defeat in the opening game with convincing victories.
After thrashing Wilkinson 6-0 he beat Hopp 6-1, with his impressive leg difference meaning Clayton had to beat Wilkinson to go through.
Clayton reeled off four successive legs to take control of the decider, and although Wilkinson took a leg against the darts to threaten a comeback, a 121 checkout for a 12-dart leg provided a fitting finish to his night.
The opening semi-final group will take place on Wednesday and will be contested by Gary Anderson, Mike De Decker, Dave Chisnall and Jelle Klaasen. The top two in both semi-finals will advance to Friday's Championship Group, where the title will be decided.
