Kirk Deighton now command a nine-point advantage in Division One after title rivals Scarcroft crashed to a 23-run defeat at Barwick-in-Elmet.
Deighton franked the form book in a four-wicket success over bottom of the league Church Fenton, despite the presence of a former international player in the hosts line up.
Connor Williams, 42, scored nearly 8,000 runs in first class cricket for Barodaf in India and made one test appearance against South Africa in 2001, only for the match to be made unofficial later due to protests over the suspension of Virender Sehwag.
The left-hander smashed a half century opening the batting for Fenton but his innings of 73 lacked support with the home team dismissed on 156. Scott Jaffray (5-23) and Rich Ward (4-50) took the wickets.
Jaffray then topscored with an unbeaten 38 as the league leaders reached the target for the loss of six wickets.
Young wicketkeeper Ewan Hardy scored 56 as Barwick's 170/9 proved too much for Scarcrof, as Jake Cullen took 5/35.
Bilal Shahid (34) was the only man to get going for the second-placed side, while Nazakat Hussain had earlier claimed five wickets.
Bilton-in-Ainsty remain 14 points off the top following a commanding win over Shadwell. Luke Schumann (67no and 4/22) and Tim Lambert (5/20) produced the goods as Shadwell were dismissed for just 78 in reply to 157/5.
Second bottom Old Leodiensians failed to improve their survival chances in a 40-run loss at home to South Milford.
Contributions from Peter Batty (43). Ben White (41), Alex Wards (49no) and Paul Hebden (37no) gave Milford a healthy 203/4 before Dan White's 5/39 restricted the hosts to 163/9.
Hillam and Monk Fryston also won by 40 runs in a low-scoring affair against Garforth Parish Church.
Adrian Joynson's 53 proved pivotal for Hillam who had Garforth staring at the prospect of a humiliating score before last pair James Pegg (24) and youngster Tom Conboy (21no and 5/42) put up resistance.
St Chad's and Sicklinghall's match was rained off.
Rufforth's perfect record in Division Two came to an end as the weather washed out their match at Thorner Mexborough.
However, the leaders still extended their lead as Ledsham and Headingley Bramhope both lost.
Rufforth's neighbours Long Marston (146/9) did them a favour by beating second-placed Ledsham (108ao) by 38 runs, thanks to Joe Eyles' 4/19.
Headingley were bowled out for just 95 at Scholes and the hosts claimed victory by four wickets.
Meanwood (120/3) moved clear from the drop zone with a seven wicket win over Sherburn Eversley (118ao).
Meanwood had two pool players in their line-up and both made vital contributions with Imram Pandoor taking 3/34 and Syed Hussain scoring an unbeaten 41.
Kirk Hammerton's clash against St Chad's A was washed out, as was the match between struggling pair Garforth Parish Church and Saxton.
