Backing up from his origin comeback on Wednesday, Fittler could?ve been excused for being tired but the captain led the charge early on scoring the Roosters opening try.
Conceeding another try by Todd Byrne and trailing by 12 points after just ten minutes things went from bad to worse for Newcastle as George Carmont was sin binned for a professional foul and in the following set Fittler went over in the corner.
A Minichello try and Chris Walker penalty goal extended the Roosters lead to 22-0 at half time and had Newcastle staring down the barrel at a 4th straight loss.
The onslaught continued in the second half as Cross scored a double and Walker found his way across to end the contest by the 60th min.
The only shining light for the Knights came late in the match when Tahu went over for a consolation try but overall it was a night that Newcastle would rather forget.
