Bardsey gave themselves a shot at survival going into the season’s climax with a thrilling one-wicket win against Adel.
Heading into the Aire-Wharfe Division Two game, Sameer Manjrekar’s side knew only a win would be enough as long as Bolton Villas lost.
And, with the side struggling at 138-8 in their chase towards 201, it looked all but over.
But a magnificence partnership of 42 by last pair Matthew Wells (45) and wicket-keeper Rory Kelly secured an unlikely victory.
Manjrekar also played a brilliant captain’s knock of 36 to set his side on the victory trail.
Umer Yaqoob had earlier taken 3-52 and Shahid Tanvir 3-59 to limit Adel at 200-6.
Bolton lost to Colton.
With one match left, Bardsey must beat already relegated Calverley and hope Bolton Villas lose to promotion chasers Rawdon if they are to survive.
In Division One, stand-in skipper Toby Jacklin’s fine 97 failed to lead Collingham and Linton to victory over high-flying Otley.
Seventh-placed Collingham smashed 229-7 from their 50 overs as Dave Girling (32) and Brian Leigh (34) supported Jacklin.
But Otley’s openers Stewart Smith and Ben Morley put on 111 for the first wicket.
Girling snaffled three wickets but Andy Rhodes’ half century led the visitors to a four-wicket triumph.
