Doncaster Phoenix are still in command at the head of Yorkshire One but made hard work of their 10-8 win over Scarborough at Castle Park.
Phoenix held sway despite a dour, scoreless second half in cold and windy conditions.
The seasiders edged in front with a penalty goal after five minutes, but Phoenix made their intentions clear when scrum-half Tim Elliot raced over for a try on 22 minutes, Ben Millar converting.
At that point Phoenix had two players yellow carded and were down to 13 men when Scarborough pulled back an unconverted try on 30 minutes to lead 8-7.
But Millar’s penalty goal put Phoenix back into a 10-8 lead before half time, and that proved to be the final scoreline.
Wath on Dearne suffered a 67-19 defeat after being out-classed by hosts York.
Wath won 28-12 when the two teams faced each other at Moor Road back in October, but York have gone from strength to strength since then and were 31-5 ahead at the break before continuing their scoring spree after the break.
No 8 Matt Burrows touched down for Wath in the first half but York were already five tries to the good.
After the break scrum-half Joe Bartlett and centre Ed Melmoth added their names to the scoresheet and full-back Sam Jones kicked both conversions, but it was not enough to stop them slipping to defeat.
Thornensians kept on the pace in Yorkshire Three when they ran in eight tries in a 50-5 home victory over Rotherham Phoenix.
Although there was a strong wind in Thorne’s favour in the first half, conditions underfoot were surprisingly good and all but one of the tries came from the backs in a free-flowing game.
Centre Ollie Cox scored a hat trick as well as kicking five of the conversions.
Full-back Zak Holgate scored twice, and the other tries were from half-backs Evan Johnson and Anthony Bull and captain for the day James Fenwick, at No 8, who was standing in for injured skipper Brett Hunt.
