The England rugby league side has beaten Samoa to complete a clean sweep of group wins in the Federation Shield.
Chris Aston and Ryan Atkins, returning after a broken hand, grabbed two early tries but Samoa touched down twice to close the gap to 16-8 at the break.
But England quickly snuffed out Samoa's charge as Atkins completed a hat-trick, Ashton added a second and Jamie Rooney and David Hodgson also scored.
England face Tonga in next week's final, who beat France 48-10.
