Staffordshire will play Wiltshire in the semi-finals of the MCCA Trophy after booking their place in the last four with Sunday's seven-wicket quarter-final win over Suffolk.
Craig Barker (4-33) and Attiq Chishti (3-29) did the damage as Suffolk were bowled out for just 121 at Longton.
Peter Wilshaw then hit an unbeaten 45 as Staffs got home with more than 20 overs to spare on 122-3.
Staffordshire's meeting with Wiltshire will take place at Leek on 1 July.
The fixture will be a repeat of Staffordshire's last triumph in the competition - their 69-run win in the final at Lord's in August 1993.
Wiltshire, who reached the last four with Sunday's five-wicket win against Devon, have never won the competition in its 29-year history.
The other semi-final will be at Dean Park, Bournemouth, between 1988 winners Dorset and Cumberland, victors in 1989.
