Bruce Percy, Richard Vigars and Richard Wild (35 not out) were the chief run-makers in the defending champions' 172-8 total.
Gary Bright picked up 4-33 for the visitors, who were dismantled by Stuart Bellwood (3-35), Percy (2-24) and Vigars (2-22). Ackworth stay in touch with the top three after comfortably overcoming Old Sharlston by seven wickets.


Kevin Marshall claimed 3-19 from 11 miserly overs and there were two wickets apiece for Jordan Harvey and Fred Gunthorpe as Sharlston were sent back for just 135. Opener Jonny Hughes top-scored with 29.
Stuart Coleman and Chris O'Grady shared an opening stand of 63 to put Ackworth on their way, witih David Harris (31 not out) and Braydon Clark (33 not out) seeing the job through with another half-century partnership.


James Robinson (51) and James Dunn (50) struck half-centuries as Featherstone amassed a competitive 217-8 at Sandal.
But the home side got home by five wickets, thanks largely to a fine knock of 72 from Amjid Sadiq.
Eddie Wilson's five-for inspired Whitley Bridge's 25-run win at Division Two rivals Darton.


He claimed 5-29 from a match-defining 9.2-over stint after Darton, requiring 196, looked in good shape at 114-3. Joe Simpson and Carl Walton took two wickets apiece to dismiss the home side for 170.
Earlier, opener Chris Smith, Adrian Parker and tail-ender Reece Ponting (29 not out) made vital contributions to Whitley's 195 total.
Smith cracked four fours and two sixes in 47 while Parker hit six boundaries and three maximums in a hard-hitting 44.
Fairburn remain top of Division Three (East), despite losing by 26 runs at Thurnscoe.


Four wickets each for Arunava Banerjee and Simon Abdy were in vain as Fairburn were dismissed for 141. Banerjee top-scored with 44 and Si Abdy hit 22 from number ten but their efforts with bat and ball were not enough against a home side inspired by a knock of 95 from opener Dave Whitehurst.
Whitley Bridge seconds stay bottom after losing a close game with fellow strugglers Fishlake seconds.


Tom Holmes (26) and Matt Daniel (22) might have won it for Whitley but for some needless run-outs. Nathan Reeson made 25 for the home side, who were all out for 132 (chasing 141 to win) and Martin Hudson claimed 5-40 from 14 overs, four of which were maidens.
Division Three (West) leaders Allerton Bywater slipped to only their second defeat of the season at home to Darton seconds.


Dave Whelan (3-25), Scott Taylor (3-27) and Steve Clowes (2-18) bowled lovely spells to limit Darton to 128.
Opener Tony Stuckey marked his first appearance of the year with a patient half-century as Allerton reached 104-4 with 11 overs left.
But left-arm bowler Sam Hawley bamboozled the middle-order and tail to take 4-11 from eight overs - and leave the hosts' reply six runs shy of the target.
