Stoke Bruerne collapsed from 132-5 to 142 all out to hand Grendon and Prims a four-wicket victory in Northamptonshire Cricket League Division Four.
Having been put into bat, Stoke made a poor start with openers Charlie Edwards and Perry Moore both out early on.
Simon Orme (12) and Marc Bliss (61) then began Stoke’s resurgence as they helped Stoke to 116-4 before Stoke lost five wickets for 10 runs to finish all out for a below-par 142.
Grendon made a swift start in reply, reaching 74-0, before Dave Weston removed Steve Hanwell for 45.
Sam Heath then ran out Julian Barford while Weston took three further wickets but it was all in vain as Grendon eased over the winning line.
Stoke travel to Geddington this weekend.
