Having won their first five games of the season, the Warriors have now lost three of their last five as they were being punished for an error-ridden performance, being held scoreless by the Roosters at Mt Smart.
For the second time in three matches, Stephen Kearney's side were completely outplayed as the visitors led 14-0 at halftime before rolling to a 32-0 victory. They failed to match the physicality of the Roosters' forwards, who produced their best display of the season.
