ASHCOMBE Park IV extended their lead at the top of Division One to two points, following a convincing win against mid-table Dyers Arms II.
Earl Davis was the only scalp for the Dyers throwers, who despite this set-back will be pleased that their top-flight status has been retained for another season.
The top two clash at the Cricket Club next week in one of the biggest games of darts Leek has seen for many years.
Elsewhere, Horseshoe have clinched promotion from Division Three to Division Two.
The Longnor pub team, skippered by Danny Bourne, have conquered all before them this season, and are aiming to become one of a select group of teams to negotiate an entire season without losing a single game.
They leave Windmill and 'The Gunslingers' from The Plough to battle over second place and the final promotion spot – with Windmill heavy favourites to join Horseshoe in Division Two.
Finally, there's a real scrap for the title developing in Division Five between Valiant and Boat Inn II.
The Boat finished well adrift of Ball Haye Tavern IV in last week's fixtures, allowing the Valiant to retake the lead in the division with a strong performance against struggling Bird In Hand. The two sides will meet in the final league game of the season, with home advantage for the Valiant.
The chase for the Division Five silverware is destined to go right down to the wire.
