Doncaster Phoenix are just one more win away from securing the North One East title after a 59-6 victory at bottom side Beverley.
The East Yorkshire outfit took an early lead with a penalty after five minutes.
However, Phoenix went ahead just minutes later when full-back Dan Porter touched down.
They extended that lead when flanker Rob Debenshire raced over on 17 minutes and fly-half Jamie Lennard converted to make it 12-3. Winger James Wright’s try three minutes later extended Phoenix’s lead to 17-3.
A second penalty from the hosts did little to dent the Phoenix’s charge and Debenshire’s second try was converted by Lennard to make it 24-6.
Outside centre Will Burden got his name on the scoresheet after 35 minutes, Lennard converting, and captain Andy Ellis also ran in shortly after, with Lennard’s conversion making it 38-6 at the break.
Wright’s second try came on 45 minutes, hooker Will Holding scored on 65 minutes and Burden added another on 70 minutes. Lennard converted them all as the Phoenix recorded a 59-6 success - a result that leaves them 18 points clear of Morley with games fast running out.
Wheatley Hills were left to salvage a losing bonus point when an injury time try saw hosts Percy Park edge to a 16-15 win.
Both sides scored two tries but the home side clinched the game thanks to two penalty goals to the visitors’ one penalty and a conversion.
Wheatley were awarded a first half penalty try which full-back Owen Gillvray converted.
A penalty by Gillvray kept them in the hunt as Percy Park turned round just 11-10 ahead.
Wheatley’s hopes were raised midway through the second half when winger Reece Garbutt raced over for a try, putting them in front at 15-11.
But those hopes were just as quickly dashed when, on virtually the only occasion in the second half that Park looked like scoring, they broke through to touch down in the corner with the last play of the match.
