The win sees Westoe currently in joint second place with Barnard Castle on 98 points, with league leaders Durham City on 105 points.
They will need to secure two more five-point wins against Novos tomorrow and Gosforth next Wednesday to stand any chance of clinching the play-off slot.
Westoe travel to Novocastrians tomorrow where Shields have won the last three meetings.
However, they won’t be taking their opponents lightly after they Horden last Saturday.

With Westoe struggling to shift into the higher gears, Ponteland regained the lead with a penalty kick.
With minutes left of the half, quick support allowed McKenzie to cross for Westoe’s second try of the day.
A drive by Anthony Rumis set up the ruck for Sam Gaff to pick and drive over the line for a half-time lead of 19-8.
