A 10-wicket rout at the hands of Read condemned Barnoldswick to relegation to Section B of the Houldsworth Solicitors Ribblesdale Cricket League on Saturday.
Richard Sharples took 5-6 as Barnoldswick were dismissed for 90.
With only two games to play, the Victory Park side - champions just two seasons ago - cannot catch third-bottom Oswaldtwistle Immanuel, with Ramsbottom Cup winners Ribblesdale Wanderers looking set to join them in the second tier.
Against Read, Luke Hodgson’s men were in trouble pretty much from the off.
At 11, Faisal Hussain (6) was caught by Elliot Lowes off Brandon Scullar, and Umer Saddique (10) followed at 25, caught behind by Read skipper Kyle O’Connor off former Earby professional Jon Harvey.
Opener Abdul Saddique lost Louis Delport (6) at 36, caught by Thomas Turner off Lowes, before the best partnership of the innings - worth 25 - with his captain.
Hodgson (5) was also pouched by Turner to give Sharples his first wicket, and John Hall followed without adding to the score, Harvey taking the catch off Sharples.
Christopher Lemon was out first ball at 73, trapped by Harvey, before opener Saddique was seventh man out at 87 for a 67-ball 29, bowled by Sharples.
The last three wickets fell for three runs , Sharples bowling Sajid Akhtar (1) and Mason Naylor (0), before Jordan Howarth-Hynes was out lbw to Omar Hussain without scoring.
Michael Rawson finished on 20 not out off 18 balls.
In reply, O’Connor (38 not out) and Joey Marshall (44 not out) took just 10 overs to knock off the winning runs, as the 20/20 Cup winners made short work of their target.
Barnoldswick have a free date tomorrow, but host Ribblesdale Wanderers on Sunday, before bringing their campaign to a close a week tomorrow at champions-elect Clitheroe.
Earby could replace their derby rivals in the top flight as they go into their last game at home to Brinscall tomorrow five points clear of third place Salesbury in Section B.
Earby are only six points adrift of leaders Cherry Tree, who need just two points from their final fixture at home to Edenfield to guarantee promotion - and will go up as winners if Earby slip-up.
Salesbury are at Euxton. Matches start at 1 p.m.
Earby were denied the chance to seal promotion on Saturday by the weather.
Euxton made 219-5, with Preston White hitting 102, but at 37-2 in reply, the match was abandoned.
