A bonus point victory consolidated Dinnington’s fourth position in the table as they overcame Alnwick 27-12.
The win them up nicely for their last two games of the year, which begins with a vital game next week when they face third-placed Wheatley Hills away.
Both sides had half chances in a bright opening 10 minutes to the game.
Dinnington forced a twenty-two drop-out with their first attack, but handling errors prevented them keeping the pressure on.
Alnwick replied with a penalty kick to the corner, but then lost the ball at the line out as Dinnington turned possession over and cleared their lines. Minutes later, Dinnington attempted the same move, at the other end, and opened the scoring with a try from Will Marshall, which was converted by Chris Williams.
Alnwick came straight back and two minutes later they crossed in the corner to cut the home lead to two points.
Dinnington were enjoying the majority of the possession but, by trying to force the play, were squandering chances.
Twenty minutes into the game they thought they had scored again, but the try was disallowed for a forward pass.
However, they kept the pressure on and five minutes later Marlon Miller touched down. The conversion came back off the post.
Further chances came and went, with handling errors the main cause, but with the last action of the half, Dinnington ran the ball from a penalty and, after moving it through hands, John Marshall scored in the corner.
The conversion was off target so Dinnington went into the break with a 17-5 lead.
The second half started with Alnwick on top.
They were helped by Dinnington conceding penalties in the opening minutes, but the closest they came was an attempted catch and drive from a line out which Dinnington turned over and cleared.
The visitors then attempted a kick and chase moments later, but the kick had too much on it and the ball went dead.
Dinnington regained their composure and 10 minutes into the half extended their lead with a try from Jalan Farris following a line out.
This should have been the catalyst for Dinnington to move away, but they continued to make errors on attack either with misplaced passes or handling errors. This allowed Alnwick to stay within touching distance and had the visitors taken any of the few chances they created the game could have become a tense affair.
But they were off target with a penalty kick, failed to control possession at a catch and drive and put too much on a kick over the top which gave the home defence time to clear.
Five minutes from time, Dinnington finally put the game to bed when Tyle Stimpson crossed in the corner.
However, Alnwick, who had battled all game, had the final say as their scrum-half took a quick tap penalty and nipped in under the posts for a converted try.
