Collingtree made it four victories in four home outings as they defeated struggling Kingsthorpe 15-0 to go top of the group B table.
Most of the damage was done early on as Robert Smout and Trevor Twelftree clinched the opener by five holes before Robert Horton and Tony Greenhill took the next tie by four.
Although Craig Hartwright and Alasdair Gibson extended the lead to 13 holes in game three, the visitors fought hard in the final three matches to keep the final deficit down.
Kingsthorpe came into the contest in good spirits after leapfrogging above Daventry at the bottom of the standings with an 18-0 home victory.
Although four of the ties were close games, the other two matches saw Bob Bason and Mark Parry (six holes) and Adam Goodacre and Michael Knight (six holes) record convincing home wins.
Kettering kept alive their chances of topping group A by winning their penultimate match of the season 17-4 away to Rushden.
Rob Aarts and Richard Grove (three holes), Mark Hastie and Steve Wade (four holes) and Nigel Hanger and Phil Kelly (five holes) put Kettering into a dominant position at the halfway stage.
The visitors took the next tie by one hole and although Ricky Beasley and Martin Eaton (four holes) responded for Rushden, the away duo of Craig Abbott and Michael Askew (four holes) wrapped up the victory.
Kettering lead the table by two points from Brampton Heath, Northampton and Wellingborough, who all have games in hand.
Oundle’s hopes of finishing runners-up behind group C winners Overstone Park improved after they defeated Priors Hall 20-1 at home.
With Dave Bailey and Dave Turner strolling in with a six-hole victory under the belt in the opening tie and Andy Burrow and Alan Boswell winning the fourth game by the same margin, the result was rarely in doubt.
