Sheffield saw Featherstone on Thursday, prevailing 28-12 over their most local rivals. Yere, Lindsay, Cook, Wood and Green got amongst the try-scorers.
There were two crucial fixtures in the race for top spot on Monday, though the relegation battle took centre-stage.
The results mean Leigh approach the final weekend of league fixtures in the relegation zone.
Though four clubs could still face the drop, as Toulouse, Batley and Gateshead are not yet safe. Batley travel to Featherstone and Toulouse are away at Halifax in tricky away ties.
Gateshead will fancy their chances of scoring a win at Doncaster, while Leigh are the only side to have a home match as they tackle Whitehaven.
Astonishingly, there could be as little as 11 points between the regular season league leaders and the side in the second relegation spot come the season’s end.
