Stoke Potters sealed their place in the last four of the Knockout Cup after defeating reigning champions Buxton.
The Potters trailed 45-44 going into the rearranged second leg of the tie at Loomer Road on Saturday evening.
Jaimie Pickard collected five race wins as Stoke cruised to a 57-35 win on the night, prevailing 101-80 on aggregate.
"They proved tonight what they are capable of," said Stoke manager Malcolm Vasey. "They really want to bring some silverware back here this year."
All seven Potters riders contributed at least five points in the meeting, with Tim Webster and skipper Tony Atkin both scoring 10.
Vasey continued: "We now hope we get a favourable draw in the next round.
"I hope we manage to avoid Dudley and are able to race them in the final.
"In my opinion, it would be a fantastic final for the Midlands if both teams made it through."
