SEAHAM delivered arguably their worst performance for several seasons as they crashed 21-0 at home to Newton Aycliffe.
The visitors dominated in all areas of the game, running in three well-executed tries courtesy of slick handling and smart support play.
Seaham’s efforts were hampered by silly errors which conceded many penalties and stifled any prospects of them battling their way back into the game.
Two of them were converted to complete the scoreline.
To compound matters further, Seaham were forced to play a quarter of the game a man down after skipper Ben Bell and Ryan Pink were yellow-carded for breakdown and tripping offences.
The wheels have well and truly fallen off Seaham’s promotion challenge following this disjointed performance, but they are clearly not ready for life in Division Two.
With promotion now out of the equation, they face a battle to consolidate third place with Newton Aycliffe and Sedgefield.
H Horden’s march towards North One East suffered a set-back when they lost 27-17 at Medicals – their first defeat in five matches.
But despite their loss in Newcastle, Glenn Bowman’s team remain in charge at the top.
Horden hold an 11-point lead after second-placed Blyth were hammered 44-22 at home by Durham City.
