With the Joseph Fee cup final looming this Saturday, Rangers travelled to Doncaster with 14 fit players including coach Craig Young.
Rangers got off to a flying start with stand-off Darren Robinson making a great one-on-one steal and racing over for a converted try to put his side 6-0 up.
That should have set the platform, but Rangers became complacent and let in four soft converted tries to trail 24-6.
Rangers were thrown a lifeline when veteran Young introduced himself and carried the ball through before smartly offloading to Elliot Briggs who sent full-back Gary Proctor in for a converted try.
Rangers got their flowing rugby going as Robinson went over for his brace, the extras were added, and on the stroke of half time, after great running from Andrew Houlihan, man of the match Andrew Esmond sent Jordan Sild in for a try to take the half time score to 24-22.
Quick off the blocks in the second half, Gary Proctor put Rangers in front 28-24 and after handbags at six paces Robinson got himself sin-binned and Bentley ran in two quick unconverted tries in to take the lead, 32-28.
Robinson came back on and aided by his bullet passes Rangers quickly scored two converted tries, first by Stuart Proctor, and then Briggs, who had a great game, to take the lead 40-32.
Again great running and defence by Alan Bottomley and Lee Buckley kept Bentley at bay before smart work from Esmond put Rangers out of reach with a converted try with a couple of minutes remaining.
Bentley again picked the ball up from a knock and scored a deserved try.
“It was a frantic phone call session for Nigel Briggs and I on Saturday morning, with the first team having so many injuries and the second team having their semi final,” said Young.
“I said to the players just lets go and enjoy ourselves.”
