The on-form Dons strengthened their play off bid with a fourth successive win over fellow top eight chasers Whitehaven.
Doncaster were as dominant as the 46-4 scoreline would suggest, exposing a lack of ideas in their visitors until the game was well out of their reach.
An open early passage was broken as Liam Kay opened the scoring for the Dons after seven minutes with a superb run in from 40m.
Much of the Dons’ best work came from the solid platform of defence, not allowing Whitehaven a sniff of the line.
By 25 minutes, a commanding lead had been opened up with Mike Emmett and Brett Waller both powering their way over.
Whitehaven got off the mark on 28 minutes with their first real attack, Craig Calvert surging over on the wing.
It proved to be their only scoring mark on the match and the Dons cemented their position just before the break with Chris Spurr collecting a perfectly-timed Paul Cooke pass to power over.
Impressive winger Dave Scott added to the tally nine minutes into the second half, collecting the ball after a string of passes to surge over.
Lee Waterman produced an excellent individual effort from 20m, charging through a tackle to score on 52 minutes with Scott missing his only conversion of the afternoon where he played the starring role.
Whitehaven enjoyed their first decent spell of possession in the later stages but never looked like adding to their score.
And the Dons hammered home their dominance with two tries in the last ten minutes, Scott and Spurr both adding their second of the afternoon.
