Collingham are now all that stands in Beckwithshaw’s way from securing the Division One title after the league leaders defeated Kirkstall Educational.
Beckwithshaw would have been confident before taking on the league’s bottom side and already-relegated Kirkstall.
The league leaders batted first and set Kirkstall a 253 target to win after Ben Quick (66) and Eugene Burzler (109 no) led the way.
In reply Beckwithshaw were always comfortable with Kirkstall never in the chase with the visitors eventually falling for 167 all out.
The result means that if Beckwithshaw take maximum points from their final league fixture against Collingham they will become Division One champions.
The only side that could still catch Beckwithshaw are current champions Otley, who remain two points off the lead after beating Ilkley convincingly by 128-runs.
Otley batted first and recorded a total of 244-8 with James Davies top-scoring with 61. Ilkley could manage only manage 116 in reply as Chris Thompson (6-25) shone with the ball.
Otley are at home to North Leeds on Saturday and will be looking to snatch the title away if Beckwithshaw slip up.
Elsewhere in Division One, already-relegated Steeton lost again as they fell by 94 runs to Rawdon. Steeton had elected to field first but Rawdon’s 251-5 proved to be way too much. Andrew Duckworth put in a matchwinning 141-runs off 103-balls for Rawdon, who are set to finish mid-table.
Burley will finish third this season but Beckwithshaw’s final-day opponents Collingham caused an upset, defeating them by one wicket in a low-scoring affair.
After toppling the Burley batting order for just 115, the visitors crawled to victory after 28 overs.
Pool’s great run of form came to an end at the weekend as they fell to Horsforth, who could be a team to watch next season.
Horsforth elected to bat first and, despite losing two early wickets, Byron Boshoff (51) and Charlie Swallow (92) led the way to the home side scoring 250-5.
In reply Pool managed only 135 all out with Andrew Robinson (5-62) and Garteh Lee (4-17) performing well with the ball.
The result means Horsforth and Pool are likely to finish the season fourth and fifth respectively.
In the remaining game in Division One, Bilton put in a fine performance against fellow mid-table side North Leeds to win by eight wickets.
Division Two is all settled going into the final weekend of games with Colton Institute and Guiseley already confirmed as promoted and Harden will be the one team to be relegated to Division Three.
Division Three’s promotion places have now been confirmed with Horsforth Hall Park, Leeds Modernians and Tong Park Esholt all being promoted to Division Two.
The three teams confirmed their promotions with wins at the weekend but the title in Division Three is still up for grabs with all three set to scrap it out.
Horsforth Hall Park currently lead the way and know a win at home to Silsden will secure the title.
But Leeds Modernians, who host Bardsey, and Tong Park Esholt, who host Olicanian, will be hoping they can capitalise on any slip ups.
