Red House Farm were looking to put pressure on leaders Walker Central who were in cup action, but went down to a surprise defeat at Stocksfield.
The Griffins claimed only their second win of the season with goals from Gav Watt and Philip Davison in a battling performance, while Patrick Collins struck for the visitors.
With just six points separating the top eight teams, Blyth Town were relieved as Malcolm Morien hit the only goal against Shankhouse.
Town are the biggest scorers in the Premier Division but it took just one moment of magic from Morien just before the hour to settle a hard-fought fixture that was played in the right spirit.
He drilled in left-footed off the woodwork to clinch into on a heavy, rain-sodden pitch.
Wallington trooped off into the dressing rooms drenched but happy as they turned things around to beat Seaton Delaval in a downpour.
John Paxton had shot the Greens ahead but goals from Stephen Howes and Daniel Young gave Delaval the advantage before the break. Ben Fenwick fired in a free kick to level and further goals from Justin Millican and Jordan Nellis won it despite Wallington being reduced to ten men.
A goal in each half from Darren Riddell and Joe Moscrop gave Ashington Colliers a deserved win over Carlisle City, who netted courtesy of a Darren Addison penalty. Jordan Miller scored twice in a minute from the penalty spot for Percy Main in a thrilling draw against Northbank, who had led with goals from Nicky Routledge (2) and Ricky James.
Chris Laidlaw got the other for the Villagers and Miller’s day was spoilt by a late red card. Lee Hamilton lashed in for ten-man Killingworth Station as they also shared the spoils with Whitley Bay A, who had Dillon Blake on the scoresheet.
