A Mark Butel double helped Slazenger to a comfortable 4-1 win over Norton that condemned their visitors to relegation.
Slazenger dominated from the start but couldn’t convert their numerous chances as both Butel and Kev Windler went close in the opening stages.
Eventually James Swinden broke the deadlock, deflecting a Simon Chamberlain shot into the net following fine work by midfield pairing Nick Webb and Dave Kaye.
They doubled their lead when Paul Wiper arrived at the back post to sweep his shot home.
The hosts were then reduced to ten men before the break but held on comfortably and in the second half confirmed their superiority.
Man of the match Butel grabbed the first of his brace and he completed his side’s scoring following converted Slazenger pressure.
Norton scored a late consolation but it wasn’t enough to keep them in North East Division 2.
On Saturday, Slazenger travel to Gateshead with their Division 2 status safe.
