Blyth entertained Wallsend in a rearranged fixture but due to a bachelor party were forced into numerous changes.
These included playing Cliff Brookes, normally a fly-half, as hooker and centre Callum Bradwell as open-side wing forward.
In the opening quarter it looked like the number of changes would prove too much as Wallsend piled on the pressure and were rewarded for turning down a kickable penalty in favour of a scrum which resulted in the first try.
Blyth hit back almost immediately when stand in fly-half O’Neil passed inside and looped around his centre for the return pass to score between the posts, unusually the kick was charged down.
The home side began to gel and a break from inside his own half saw Allen chip over the visitors’ defence to score, which was converted by Reece.
Blyth’s third try came from a Wallsend lineout. The ball was chipped through for Smith to touch down, with Reese adding the two points.
The bonus point try was scored by Heslop, playing his first game for some time, but this Reese missed the conversion.
Right on half-time the visitors pulled three points back to leave the interval score 24-8 to Blyth.
The second half started with Wallsend creating pressure on the Blyth line resulting in an unconverted try.
The home forwards hit back hard and were unlucky to be held up over the line twice before Jarvis carved his way through the defence for the fifth try to seal the win.
On Saturday Blyth are at home to high-flying Bishop Auckland, kick-off 2.15pm.
On a sad note, Les Haden, who celebrated is 89th birthday at the club only three weeks ago, has passed away and the club passed on its sympathies to his family.
