Bradford Bulls secured a victory in new coach Francis Cummins' first match in charge as they beat Dewsbury Rams 48-6 at Tetley's Stadium.
Second-row forward Elliott Whitehead ran the Championship side ragged with a first-half hat-trick of tries.
Heath L'Estrange also crossed before the break, with debutant full-back Jamie Foster adding four of his perfect eight conversions to make it 24-0 at half-time.
Whitehead turned provider after the restart to set up Matty Blythe on his Bradford debut and further scores from Matt Diskin and Manase Manuokafoa extended the visitors' advantage.
A fourth try for Whitehead in the closing stages completed a superb afternoon for the 23-year-old.
Whitehead's final score came shortly after Dewsbury had finally opened their account through Dario Esposito's touchdown.
