Inspirational Queensland star Cronk incredibly featured for all but the final two minutes as Trent Robinson's side set up the 21-6 win with a dominant first-half display.
The victory came despite their half-back being forced to the fringes for much of contest, as he was nursed through at just "30 per cent" fitness according to Cordner.
Cronk had been a major doubt leading into the match after seriously injuring his shoulder in the Preliminary Final against the South Sydney Rabbitohs eight days earlier.
