Wellingborough rarely looked in danger of losing at home to Kingsthorpe as they recorded a 4-1 victory against last year’s beaten semi-finalists.
Tiger Adams and Chris Billson (5&4) took the opening point for the hosts, before Elliot Morgan and Richard Brown won the 17th hole to double the lead.
Although the visitors took the third game, it proved too little too late as Jamie Milligan and Duncan Cornish stormed to a 5&3 win, while Jon Harris and Mark Davis added a further home point.
Northants County kept their nerve in the majority of the close games as they edged a tight away contest with Kettering by a single point.
Despite losing games two and three, County replied thanks to Joe Larkins and Harry Larkins on the 18th.
Ben Smith and James Dunkley added another away point on the closing hole, before Paul Harris and Daniel Roberts (2&1) wrapped up a 3-2 victory.
