Both Kettering and Wellingborough collected valuable wins to aid their battle against the drop.
It was a tremendous weekend in Midlands One East for the Blues who not only blitzed their fellow strugglers Market Bosworth 45-0 but also saw relegation rivals Spalding, Loughborough and Newark all lose.
It means they now sit five points above the third drop spot with three games remaining.
Boro had a similarly profitable day as they thumped Vipers 41-19 away from home in Midlands Two East (South).
An unconvincing first-half display saw them take a one-point lead into the break. A Pete Vickers penalty and Steven Gall try gave them the edge.
But a half-time pep talk from head coach George Shipman - and with skipper Owen Tomalin leading by example - the second half saw Borough score five tries and gain a bonus point.
A Vickers try was quickly followed by one for flanker Adam Lambert - both converted.
Gall then got his second and his team’s fourth to earn the bonus point before prop Kevin Osborne crossed the line - for the first time in quite a while - to make the game safe at 36-7.
The visitors relaxed a little and Vipers scored two tries but winger Luke Gardiner ensured there was a happy ending with another score in injury-time.
Rushden & Higham’s ambitions are focused at the other end of Midlands Three East (South) and they maintained their promotion hopes with a 21-6 win over Old Newtonians.
They now sit three points behind county rivals Stewarts & Lloyds - with a game in hand - as the battle for second place intensifies.
