Hartshead secured a comprehensive 5-0 derby victory over Howden Clough in West Yorkshire League Division One last Saturday.
Victory leaves Hartshead seventh in the table, although their hopes of challenging for promotion diminished several weeks ago, while Clough are now nine points adrift at the foot of the table and seem certain to be relegated.
Clough have just four matches of the season remaining, having played more than any of the sides around them, and face a trip to Otley Town on Saturday.
Joel Farrer and Benjamin Smith led the way with a brace apiece for Hartshead, while Stuart Kiltie completed the tally.
