Stewarts & Lloyds emphatically claimed the honours from their county derby clash with Rushden & Higham.
The Occupation Road side were too strong for their local rivals and ran out 31-7 victors in their Midlands Three East (South) encounter.
It was a victory that took them top of the table as leaders Stamford saw their game with Old Newtonians postponed.
However, Stamford now have two games in hand on their rivals and sit five points behind S&L.
Kettering’s trip to Ilkeston proved as tough as expected and they returned having lost 24-17.
The results leaves the Blues in ninth spot in Midlands One East with half the season gone.
Wellingborough, still smarting from a 15-point deduction that dropped them to the foot of Midlands Two East (South) missed the chance to gain important ground on one of their relegation rivals.
Having been docked points and fined by the RFU for failing to identify a player responsible for landing a punch in a game against Oadby Wyggs last season, Boro were highly motivated and keen to climb their way back up the table.
But, despite having victory in the sights against Leicester Vipers, they slipped to an 18-15 home defeat.
Andy Seaton’s breakaway try was converted by Tom Mair - who also added a penalty - while Darrell Reynard touched down in the second half.
It was not enough to seal a vital success, though.
Oundle collected an impressive win on their trip to Bourne in Midlands Four East (South).
The home side had been in better form than their visitors over the previous month but the Owls were clearly better and claimed a 43-0 success.
Tries came from Dan Burns (2), Joe Rice, Ben Milborne, Matthew Faulder, Sean Murray, George Swallow with Swallow converting three and Milborne one.
Old Grammarians came so close to adding another victory but ultimately lost out 13-11 to Westwood.
Throughout the afternoon the OGs forwards were dominant in rucks and mauls and nothing was getting through the backs but they were unable to take their chances.
Winger Ryan Groves had a busy afternoon, made some excellent runs and got their only try in the game.
Indeed with all the possession and attacking play they had OGs should have been celebrating another win but there were too many “if only” moments when the ball was lost or fumbled with a scoring opportunity begging.
Corby were decimated by illness but still managed to put together a good performance against Thorney.
It ultimately was not enough and they lost 15-5.
However, it was a creditable display having asking some of their semi-retired players to pull on a shirt and play 80 minutes of rugby.
Jack Chennell touched down for Corby but two unconverted scores from the home side in the last 10 minutes took the game away from them.
Manager Ricky Egan said: “It was a bit disappointing. Some of our guys played even though they were clearly not well. We also had call offs, that didn’t help.
“We had to dig deep into the squad this weekend and I still thought we put in a good shift.”
