Home victories are proving difficult to obtain in Group A after Northants County and Northampton both avoided defeat on their travels.
County, who won at Overstone the previous week, edged a thrilling contest at Rushden as Lee Ault and Andrew Chubb’s big victory helped the team triumph 10-9.
Northampton remain top of the pile however on five points after they held on for an 8-8 draw at Overstone.
Collingtree Park’s strong tail proved crucial in their home contest with Peterborough Milton as the reigning champions came through by the scoreline 14-7.
Despite leading early on, Collingtree looked in trouble when the visitors went 7-5 ahead, but the hosts quickly regained control, thanks to David Messom and Sam Patel (five holes) and Mike Clarke and Tom Low (four holes).
Kettering secured their second victory in two outings as they defeated Hellidon Lakes 17-3 at home.
The hosts were rarely in any danger as Club Vice Captain Sean Suddards combined with Alun Genner to take the opening tie by six holes, before Toby Askew and James Noble romped to an eight-hole victory in game four.
