Doncaster Town defeated Treeton by seven wickets to set up a regional final with Chesterfield in the ECB Club Championship.
Town, who famously won the national knockout competition at Lord’s in 1998, will host the Derbyshire Premier League outfit on June 22.
South Yorkshire League Premier Division high fliers Treeton became Doncaster’s latest scalp on Sunday, following wins over Beverley and Driffield in the earlier rounds.
It was far from plain sailing for Alex Gosney’s men, but half centuries from Simon Widdup and Stuart Guy helped Town reach a modest target with 4.4 overs to spare.
Treeton struggled to get their run rate above four runs per over after being put in by Gosney.
And when they lost talisman Danny Kemp for 27 with the score on 86-4, the innings was in danger of stalling completely.
Chris Cobb (44) dug deep to ensure his side reached a defendable 173-9 from their 45 overs, while Curtis Free returned impressively from his opening stint to take three late wickets and finish with 4-32.
Town suffered an early blow in reply when they lost Graeme Attenborough for eight.
But Widdup (51) and Guy, who finished unbeaten on 71, put on 107 for the second wicket to take the hosts to the brink of victory.
James Stuart departed first ball to set a few nerves jangling but Felix Odell scored a mature 34 from 35 balls to book Doncaster’s place in the regional final.
