The writing was on the wall in the first half, with a 12-0 half-time deficit being blown open to 26-0 just after the hour, with the Knights only grabbing a consolation score moments before the end.
It was Jojo Fifita that dotted down first on 16 minutes with Campbell converting, before the wily halfback crossed himself as half-time approached.
Though Campbell could not convert his own four-pointer, the playmaker added a penalty on the stroke of the break when the Knights were found offside.
If the visitors couldn’t wait for half-time, they probably couldn’t wait for the final whistle when Beau Fermor crossed on 54 minutes after Campbell had made it 14-0 with a penalty.
But still the Titans were unrelenting and it was Jojo’s namesake, David, that barrelled over to make certain of the two points. Campbell added the conversion for a 26-0 lead as the final quarter descended.
Though victory was assured, Newcastle kept plugging away and Bradman Best registered a deserved try, but the Knights were thoroughly second best.
