Mirfield Parish Cavaliers came within five runs of breaking the all time Drakes Huddersfield League record high score on Sunday.
Parish racked up a mammoth 450-3 on their way to a crushing 287-run win over Birkby Rose Hill.
Their total was just four shy of equalling the record of 454-4 set by Clayton West against Hall Bower in 2010.
Terence James led the way with a magnificent 146 not out, while there was support from captain Tim Orrell (97), Nazar Hussain (63), David Blakeley (54) and David Bolt (38no).
Khuram Sajjad led the Birkby reply with 71 but Rose Hill wilted and were bowled out for 163 as Nazar Hussain claimed 5-47.
It capped a profitable weekend for the Conference leaders after they defeated Thurstonland by eight wickets on Saturday.
James Hardcastle (5-26) and Daniel Padgett (4-20) combined to help Parish dismiss Thurstonland for 99, with Mandeep Oberio (33) top scoring.
Parish cruised to 101-2 in just 10 overs as James (45no) and Hussain (26no) saw them to victory.
Mirfield suffered mixed fortunes over the double weekend, losing on Saturday before bouncing back with a one-wicket win.
Philip Scouller (33) top scored as Mirfield were bowled out for 100 in Saturday’s game away to Thurstonland, as Henry Frankland claimed 3-35.
Thurstonland eased to 103-2 in reply, with Chris Swanson making 44 not out.
Alex Pearson (5-37) and Azad Kazmi (3-38) bowled impressive spells to dismiss Denby Dale for 107 on Sunday.
However, Mirfield made hard work of their reply and it took an unbroken last wicket stand from Daniel Gough (14no) and Emma Bolt (11no) to edge them to victory, which leaves them ninth in the table.
Moorlands have slipped out of the top two in the Championship after also suffering mixed fortunes with a win and a loss from their games.
Moorlands successfully chased down Kirkheaton’s total of 188 all out on Saturday as Andrew Fortis struck a splendid 109 not out.
Naveed Zamurad followed up his 3-38 with the ball by making 26, while Jake Dubbeldam (4-28) also impressed in the Moorlands win.
However, the Mirfield side couldn’t back it up as they suffered a 66-run defeat to Thongsbridge on Sunday, which allowed their opponents to take over at the top of the table.
Andrew Walker (4-36) and Reece Drake (3-9) helped dismiss Thongsbridge for 176, with Jack Marshall (53) top scoring.
Michael Rounding (56) led the reply but Moorlands were dismissed for 110 as William Reeves claimed 5-14 and they are now four points behind Thongsbridge and three off second places Rastrick.
