Both Kirkbymoorside and Cloughton have ensured their return to the premier division but who will gain the Division A title will go right down to the wire.
Only six points separate the two with only one week of the season remaining, the Moorsiders entertain a recently-improved Bridlington 2nds and Cloughton have to travel to the clifftops at Sewerby to take on their second team.
Kirkbymoorside remain slight favourites after sending Brompton crashing for 69, Dan Jeminson claiming 4-11 before knocking off the runs without loss, Jodie Robson leading the way with 53.
Cloughton also picked up maximum points being all out on the last ball of the 45th over at Snainton for 209, Gary Pickup, 36, and Mark Bennett, 58, the leading run scorers with the impressive Paul Kinghorn, 5-57, hitting top form with the ball once again.
On the resumption Roy Thompson, 5-23, and all-rounder Jake Dudding, 3-2, proved too strong for the home team, who were blown away for 53.
Nawton Grange proved far too strong for visitors Sewerby 2nds with Charlie Allott, 66, Jonny Pickard, 44, and Tom Garbutt, 26, taking their total to 184-4 at the tea interval before Peter Wilson blew the seasiders away, claiming 7-15 in his eight overs to have Sewerby all back in the pavilion for 37 in 17 overs.
Bridlington 2nds not only gained their second and consecutive victory of the season by beating fellow strugglers Wykeham, but they have given themselves every chance of avoiding relegation being now 10 points above Wykeham and two behind Snainton with the drop into Division B to be decided between all three next week.
Rob Middlewood proved the Bridlington hero with a match winning 106 out of the home teams total of 202-7, paceman Dave Pearson claiming 3-62 from 15 overs for Wykeham who, in turn, were bowled out by a super spell of bowling from Ewan McNab, 7-44, despite good knocks from Sam Colling, 35, James Bryant, 46, and James Shepherdson, 25.
Sherburn ensured Division A status next season by beating Wold Newton by 72 runs.
Phil Pickard, 39, and Chris Crawford, 26no, took Sherburn to 188-9 at the tea interval with Charlie Gray and Chris Hodgson claiming three wickets each for the visitors who could only manage 116 in reply, Stuart Pickard claiming 3-23 for Sherburn.
