Ashington had the win in the bag against Wallsend on Saturday but threw it away.
They started strongly and dominated the first ten minutes but failed to turn their superiority into points.
Then a breakaway try and a missed tackle in the centre found the home side points down after 20 minutes.
Ashington continued to have most of the pressure and possession and from a five-metre lineout Wallsend were lucky to get away with collapsing the driving maul.
Ash then had two tries disallowed from driving mauls by the referee who was unable to see the grounding of the ball.
The pressure finally told when replacement prop Wood crashed over for an unconverted try after 33 minutes.
The first half finished with an outstanding individual try from young centre Nathan Whitworth to level the scores.
Ashington started the second half strongly and a great run by Chris Johnstone, who probably had his best first team game, started a free flowing move which he finished off with a try in the corner to give them a deserved 15-10 lead.
Full-back Simon Barber then extended the Ash lead with a great individual try which should have given the home side an unassailable 20-10 lead.
Dickinson and Newman were both having strong games, with the return of the former giving the back row a bit more pace and an extra lineout option.
In the last 15 minutes Wallsend began to claw their way back into the game, helped by Ashington continually trying to run the ball out of defence and putting themselves under pressure.
A missed tackle in the corner allowed Wallsend to score an unconverted try, the visitors then scored a fourth try with three minutes to go, levelling the scores aT 20-20, and a fantastic touchline conversion gave the visitors a two-point lead.
Ashington had a chance to win the contest with the last kick of the game when awarded a penalty 30 metres out but Rosser pushed his kick wide of the posts.
After the defeat Ashington remain third bottom, but the gap between them and the relegation spot is eight points.
