SHEFFIELD Tigers extended their impressive winning run to 12 matches with an 8-28 victory over hosts Newport in Shropshire.
After going behind, Tigers took the lead with full-back Jon Feeley scoring and Jonny West converting - despite being down to 13 men with two in the sin-bin.
Back at full-strength, Tigers continued with winger Callum McKenzie touching down and West converting for a 3-14 lead at half time. No 8 Sam Cooke was credited with the points after a pushover try and McKenzie bagged his second try on 65 minutes, West converting both to secure a maximum five-point haul.
Two penalties from Danny Wilkinson was not enough to avoid defeat for Dinnington as they went down 22-6 to hosts York in Yorkshire 1.
And there was no more luck for Sheffield, who lost 8-18 to Heath at Abbeydale, denting their title hopes.
Barnsley saw off a challenge from their lower placed rivals to emerge 28-23 winner over Yorkshire 2 opponents Skipton. Barnsley took the lead with a penalty goal from Patrick Jensen but then found themselves trailing 6-3 before centre Andrew Appleyard raced over for a try. Appleyard’s second try, converted by Jensen, put the home side ahead at 15-6, but Skipton turned round 16-15 ahead. Barnsley’s Andrew Smith restored the lead with a try which Jensen converted, but the visitors again edged a point ahead with a converted try before two Jensen penalties gave Barnsley some breathing space.
Wath on Dearne won 29-17 at Goole. After an early penalty by their winger Ben Keen, Wath slipped 7-3 behind when Goole claimed the game’s first try, but the visitors took control with two tries from Brett Small and others from Adam West and prop Dean Hardcastle. Keen converted three.
Three penalties from Tom Jenkinson and a try from Gareth Ashcroft helped Rotherham Phoenix to a 5-14 win at Hessle in Yorkshire 3.

George Cusworth, Tris Crawshaw and Al Fawdry were the other scorers, and Will Coomer converted seven out of 10.
