Pete Webster and Tom Pateman shone as Brompton beat Sherburn by 81 runs to move into second spot in Division One.
Pateman top-scored with 61 of Brompton's 204 all out, Michael Thompson (33) and Mark Bruce (27) also contributing as spinner Jamie Thomson did his best to peg them back with 4-30.
Despite 38 from the in-form Craig Sanderson and 36 from Thomson, Webster's 5-20 and 3-33 from Tony Hulme ensured Sherburn were all out for just 123.
The games elsewhere in Division One were conceded by Staxton 2nds, Flixton 2nds and Wykeham.
Leaders Bridlington 2nds made light work of Kirkbymoorside in Division Two.
Kirkby were all out for just 58 as Ben Jackson took 5-22 and Callum Battams 2-35 as Peter Kent hit over half of the hosts' runs with 30.
Will Watts then hit 41 not out as Brid cruised to 64-1.
Struggling Ebberston 2nds stunned promotion-chasing Wold Newton with a tense three-run success.
Jacob Waters top-scored with 50 in Ebberston's 198-8, Doug Bentley adding 43 and Tom Holmes 28 as Hari Haran Gunaskaren claimed superb figures of 6-34 for the hosts.
Charles Gray then smashed 62 and was supported by Will Gray's 49 and 31 not out from Callum Morley, but this wasn't enough for Newton as they fell just three runs short of victory, Aussie Cooper Barnes taking 5-42.
Jaymaine White claimed spectacular figures of 5-1 as Forge Valley 2nds hammered Flamborough by 10 wickets in a brisk and one-sided affair in Division Three.
White's stunning spell of bowling ensured Flamborough were all out for just 72, Graeme Harvey hitting 37, while Matty Nettleton also took 3-33.
Eric Hall then clattered a rapid 67 not out in Valley's 78-0.
Flixton 2nds and Cloughton 2nds conceded their games.
Matty Jones starred with bat and ball as Scarborough Rugby Club beat Ravenscar 2nds by six wickets in Division Four East.
Jones took 2-37 along with Brett Canham (2-12), Ian Williams (2-26) and Mark Kelly (2-26) as Ravenscar posted 138-9, stalwart Jish Rewcroft smashing 67.
The Kiwi then smashed 69 in Rugby Club's 139-4 as they cruised to victory.
Scalby 3rds beat Wold Newton 2nds by 86 runs.
Newton's skipper won the toss and asked Scalby to bat first, a decision they'd regret as Scalby posted 232-8.
Brett Cunningham hit 55, Tim Barton added 53, Gareth Edmunds made 29 and Nathan Barber contributed 25 in the hosts' total, Jack Heslehurst claimed 3-60.
Newton could only make it to 146-8 in reply, Dan Reardon hitting 49, Pete Auty 34 not out and Heslehurst 29 as they fell 86 runs.
Muston and Scarborough 2nds both conceded their matches.
Forge Valley 3rds beat Malton & Old Malton 4ths by four wickets in a low-scoring affair in Division Four West.
Malton were all out for just 89, Steve Boyes taking 3-10, Daniel Boyes 3-36 and Charlie Ionascu 2-25.
George Cullingworth hit 34 as Valley then made it to 93-6, Josh Mann taking 2-9.
Wykeham 3rds conceded their game against Brompton 2nds.
