Elland claimed local bragging rights when they won 20-0 away to Ovenden in yesterday’s National Conference League Division Two derby.
Karl Fairbank’s side, with scrum half Phil Taylor to the fore, scored 10 points in each half to maintain their promotion bid.
However, Dudley Hill remain favourites for the second promotion spot behind likely champions Kells after rallying from 20-6 down at half time to win 24-22 at Pilkington Recs.
Ovenden, who will not have been “nilled” too many times at Four Fields, were unable to crack a watertight Elland defence.
The visitors’ points came from tries by wingers Oliver Fairbank and James Marshall, Taylor and loose forward Jack Fairbank.
Taylor and Jack Fairbank kicked a goal each.
Siddal lost the leadership of the Premier Division to Lock Lane, who won their big clash in Castleford by 34-30.
Defeat for third-place West Hull away to Humberside rivals Skirlaugh was some good news for the Chevinedge side.
Gareth Greenwood’s Siddal led 12-10 at half time but were unable to hang on in spite of a man of the match performance from prop Iain Davies.
Second row Danny Williams scored a hat-trick of tries for the visitors and others came from Billy Hammond, Richard Lopag and Ross White.
Chris Brooke kicked three goals.
