Keighley Cougars continued their seemingly unstoppable march towards the Betfred Championship with a 60-18 thrashing of Hunslet at Cougar Park on Sunday.
The Betfred League One leaders made it 17 wins from 17 games this season and are now on the brink of sealing promotion to the second tier.
Alix Stephenson led the way against Hunslet, scoring three of his side's 10 tries, with Mo Agoro, Matthew Bailey, Billy Gaylor, Junior Sa'u, Charlie Graham and James Feather also crossing.
Jack Miller was the other Cougar to touch down and he also slotted over all 10 of his kicks to cap a fine day for the pacesetters.
Hunslet responded through tries from Harvey Hallas, Macauley Hallett and Jordan Paga but they could not contain rampant Keighley, who are six points clear of second-placed North Wales Crusaders and have automatic promotion within touching distance.
Swinton Lions are a further two points back in third after their 94-6 mauling of rock-bottom West Wales Raiders on Saturday.
Swinton, who came agonisingly close to ending Keighley's 100 per cent record last weekend only to surrender a 20-2 lead, finished with 16 tries in the romp as Rhodri Lloyd and Jack Hansen both recorded hat-tricks while Dan Abram and Richard Lepori claimed braces.
Fourth-placed Doncaster, who are level on 26 points with Swinton, were also convincing winners on Sunday as they saw off Midlands Hurricanes 52-18 to earn their eighth successive victory.
Watson Boas scored a try treble for Doncaster, who must now turn their attention to the formidable challenge of facing Keighley next up at the Eco-Power Stadium.
Also on Sunday, Oldham brushed aside London Skolars 60-6 while Rochdale Hornets were 34-14 winners over Cornwall.
