RANGERS cruised forward to the cup final after dominating the early possession and field position.
A good midfield break by Illingworth second row forward Chris Keoghan relieved pressure and his side could have gone ahead had alert full-back Mark Horne not defused Graham Dobson’s high kick.
The visitors though were not to be denied and against the run of play went ahead on 11 minutes.
Second row forward Ross Holmes broke the defensive line 25 metres out and showed great strength to break through a number of would-be tacklers to touch down.
Brighouse hit back on 21 minutes when impressive second-rower Andy Seager made 40 metres on a weaving run to set up the position for his side to go ahead with a try from Alex Muff converted by Neil Walton.
The home side increased their lead to eight points on the half hour when Ross Young fed the supporting Horne who scored under posts. Walton converted.
By the break it was 18 - 4 as stand-off Ross Young went over from close range for a converted try.
In heavy conditions the second half increasingly became a battle among the forwards as handling errors negated attacking efforts.
Tom Ashcroft, Ash Ainley and Joe Crossland were to the fore for Illingworth, but strong home defence from Wayne Jowett, Lee Buckley, Gav Midgley and veteran Craig Young ensured Rangers remained dominant.
On the hour Brighouse, with the only points of the second half, ensured progression into the cup final when Walton crashed over under the posts for a converted try.
Best for Rangers were Reece Spurr, Horne and Seager.
