Borough will be looking to carry on where they left off when facing Belgrave away in Midlands Division Two East (South) on Saturday.
The city side beat Rushden & Higham 25-17 at Fengate last weekend and that was due to a superb second-half display against the gale-force wind.
They showed determination and grit in difficult conditions, retaining possession for long periods and making deep driving inroads into the heart of the Rushden defence.
Debutant Johnny Anderson and Chris Sansby scored tries with Harry Roe kicking five penalties. George Offer in the centre was man-of-the-match.
Borough seconds also enjoyed a good win beating arch rivals Peterborough Lions seconds 18-3 to advance to the semi-finals of the Hunts and Peterborough County Cup.
Ryan Williams and Luke Smedley scored their tries with Will Cook kicking a conversion and two penalties.
Andy Barringer was outstanding for Borough and there were quality performances as well from Cook, Cliff Casbon and stalwart prop Bruce Morley.
There was a massive shock in another local derby in the English Clubs Championship.
Rock-bottom Spalding entertained Midlands Division Two East (North) table-toppers Stamford and pulled off a 25-15 upset - a result which takes them off the foot of the table.
Star of the show was fly-half James West, who kicked six penalties and converted his side’s only try scored by left winger Kieran Lake.
A try in the final minute by Rob Shingles and a successful conversion with the last kick of the game by Craig Tandy saw Oundle boost their title hopes in Midlands Division Three East (South) by beating closest challengers Long Buckby 29-27.
