Luke Dorn scored a hat-trick as Castleford Tigers moved to within two points of the First Utility Super League summit with a thumping 54-12 victory over 12-man Hull KR.
Daryl Powell's men have been the surprise package this season and they are showing no signs of letting up in their bid for a first Grand Final appearance.
The Tigers had the two points wrapped up before the break as they ran riot on a warm afternoon in West Yorkshire.
Michael Channing and Dorn crossed twice and Grant Millington and Kirk Dixon grabbed one apiece to give the hosts a 28-0 half-time lead, a margin which would have been greater had it not been for four missed conversions by Marc Sneyd.
Travis Burns went over for the Robins early in the second half but Jamie Ellis and Dorn scored to ensure the comeback was short-lived.
The visitors were reduced to 12 men when Australian prop Michael Weyman was sent off for dissent before Jake Webster, Craig Huby and James Clare helped themselves to tries as Castleford romped to their biggest Super League win against Rovers, who scored a late consolation through Wayne Ulugia.
Adrian Purtell scored two tries as Bradford gained a vital 20-12 victory over Wakefield.
The relegation-threatened Bulls are now six points adrift of the Wildcats and safety with the possibility of the gap reducing further when an appeal against a six-point penalty for entering administration earlier in the season is heard next Wednesday.
Bradford continued a stranglehold over the Wildcats at Odsal - a run of seven games without defeat - through three first-half tries and four goals from five attempts from inspirational half-back Luke Gale.
Gale also engineered each of the Bulls tries as they completed what could turn out to be a crucial double following their February win at Wakefield.
