Siddal have a four point lead at the top of the National Conference League, with four games left ahead of the play-offs, after sneaking a 13-12 win at Hull Dockers on Saturday.
A Shaun Garrod drop goal gave them victory against opponents who had a player dismissed in each half for dissent.
Dockers may be bottom of the Premier Division but they had easily beaten Kells in their previous outing. They were left to rue their indiscipline in a penalty-laden contest.
Siddal are living dangerously at the moment, having somehow beaten Rochdale Mayfield at home the previous week.
Further absentees and injuries meant they had to draft in former coach Lee Greenwood at centre and 17-year-old Finley Hickey for his debut off the bench at the east coast.
Dockers went 6-0 up but Siddal were level by the break thanks to a Freddie Walker try converted by Gareth Blackburn.
The home side scored a second try and added a penalty for a 12-6 lead but Garrod scored his customary try and Blackburn’s kick levelled it up.
Visiting stand off Garrod then snatched the spoils with a one-pointer and second-placed Leigh Miners Rangers’ 28-10 defeat at Wigan St Patrick’s completed a good day for the Chevinedge men.
Third-placed Wath Brow Hornets are five points behind the leaders after a 40-18 win at York Acorn.
Siddal now have a couple of weekends off, returning at home to Kells on September 3.
Elland’s torrid season continued with an 80-10 home defeat by promotion hopefuls Skirlaugh in Division One.
They travel to Myton Warriors on Saturday.
