Needing to win to stay in finals contention, the Warriors led 6-0 early on Sunday afternoon but otherwise failed to land a punch as they conceded eight unanswered tries.
They also lost Gerard Beale to a serious knee injury early, while Jazz Tevaga might be suspended for a late shoulder charge on Cronk.
Tevaga was sin-binned for the hit and, while Cronk initially remained grounded, he played on without any real concerns.
