Farthingstone will have home advantage this weekend when they go head-to-head with Collingtree Park for a place in the semi-finals after Cold Ashby missed out on top spot with a narrow defeat at Stoke Albany.
Needing a comfortable win to have any chance of qualifying for the last four, Ashby put up a stern fight as they took games three and five, but lost the other three matches on the 18th hole.
The winner of the Farthingstone v Collingtree match will face Staverton Park after they topped Group D ahead of Overstone Park on points difference with three wins out of four matches.
Wellingborough booked their place in the last four in style as they completed a magnificent 4-1 victory at Silverstone.
Although Mark Davis and Isaac Redding (Wellingborough) and Matt Bishop and John Pirnie (Silverstone) shared the opening two games, the visitors quickly took control as Chris Howes and Jon Harris strolled in with a 7&6 win under their belts.
Tiger Adams and Duncan Cornish confirmed the team success by taking the 17th hole, before Tim Veal and Martin Dalton capped a brilliant away day down the last.
Kettering finished top of Group C after closest challengers Daventry suffered a 4-1 reverse at Whittlebury Park in their last match.
Needing victory to leapfrog Kettering, the away side got off to the ideal start as they took game one with holes to spare, but David Melling and Chris Van Heerden (6&5) and Rob Watson and Tim Holliday (4&3) responded for Whittlebury.
With both the remaining matches going the distance, the visitors were unable to secure any more points meaning Kettering will now take on Wellingborough in the last four at a neutral venue on Saturday, July 28th.
