Scalby continue to dominate the division, this time beating hosts Fylingdales by 23 runs.
The visitors were put into bat by their rivals and they amassed 224 runs thanks in the main to a 104-run fifth-wicket partnership between Adam Tildsley, 67, and Paul Marton, 45, Lee Kerr having added 25.
Mark Estill and Steve Husband finished with identical figures of 4-63.
Replying Mario Spagnolo, 55, and Theo Clarke, 50, featured in a second-wicket stand of 80, and with Mark Estill, 48, fell just 23 runs adrift at the close, Paul Hesp claimed 4-45 but Fylingdales did receive 10 points, which is unusual for a losing team.
Grindale eased their relegation worries but left opponents Cayton 2nds only 10 points above bottom club Staxton 2nds, whose match against Ryedale was rained off.
Grindale looked on course for an early tea, slipping to 39-6 until a vital seventh-wicket partnership of 55 between Andy Smith, 49, and James Knaggs, 38, helped boost their total to 137,
Simon Glave claimed 5-59 for Cayton from his 19 overs.
In reply Shane Williams scored 70, but James Watson’s 4-39 from 12 overs and Jamie Knaggs’ 3-9 from 4.5 had them heading home with only 123 runs on the board.
Intermittent heavy rain at Staxton resulted in their match against Ryedale being abandoned after a total of 17 overs with the visitors on 71-1, Dan Hardey being brilliantly caught one handed by Kyle Outhart off the bowling of brother Dan, Ian Smith being left on 33 and Rob Featherstone weighing in with 25no.
