Despite going behind to a Micky Paea try early on, were raced on to 18 points before the break.
Fouad Yaha scored a proper touchline hugger, Tony Gigot added a second before Brayden Willame scored the pick of the bunch with a show of real acceleration and determination.
The hype around Arthur Romano won't be subsiding after another strong performance and decent touch down. Matt Whitley and Samisoni Langi scored the remainder.
Lee Radford had a moan about injuries, Steve McNamara pointed to the nine injured players we had at home. And that was that.
