Sheriff Hutton grabbed the second promotion slot with a tenuous three wicket win which sent Scarborough down into division 4.
Josh Mainprize made 39 for the Seasiders, but Josh Wilford’s 4-14 had the innings closing on exactly 100.
Joe Schofield then made 38 as Sheriff progressed reasonably comfortably to 93-4. However Matty Kay’s 4-41 then caused consternation in the Castlemen’s ranks as Sheriff lost three wickets without a run being scored.
It then took them 13 overs to score the remaining eight runs which eventually provided a three-wicket victory.
Folkton & Flixton was the scene of another run-fest as batsmen from both sides exploited the short boundaries to improve their battin averages in a game that saw the hosts gain the better of a draw against Driffield.
Leading the way was Neil Elvidge, who struck 82 as the home side batted first.
Stuart Stocks was another half-century maker with 65, while Jamie Nesfield (41) and Richard Malthouse (40) also gave useful input in a total of 289 all out.
A Rogers had 4-30 for Driffield, who made 192 in reply but were hanging in for a draw after losing nine wickets.
Andrew Chapman (43) and Richard Grice (40) were the pick of the batsmen as Mikey Hunter took 3-36.
