Unbeaten Northampton stay in control after recording back-to-back home wins against Overstone Park and Cold Ashby.
All the damage was done early on against Overstone as Gary Slinn and Robert Smith won by 10 holes, before David George and Daniel Hayday repeated the scoreline in the next tie to help Northampton triumph 24-8.
Cold Ashby provided more of a contest a few days later, but a four-hole success from Daniel Hayday and Daryl Webster in game three and another comfortable victory for Simon Hunt and Craig James in the next tie helped Northampton win 9-3.
Ashby sit bottom after suffering a heavy 24-2 loss a few days earlier away to Rushden, for whom Chris Thacker and Michael Stephens (five holes) and Robert Day and Kane Attley (seven holes) impressed.
Peterborough Milton did just enough in all six ties at home to Cherwell Edge as they grabbed their second victory of the campaign with a 12-0 success.
Sam Balaam and Lee Talbot (three holes) in game two and Joe Maddalo and Daniel Wisbey (three holes) in the closing game were the most convincing winners as Milton maintained their slim hopes of catching runaway leaders Collingtree.
