St George Illawarra have all but claimed the National Rugby League minor premiership following a 32-10 victory over Manly at Kogarah Oval.
The Dragons hold a four-point advantage with three rounds remaining, their pursuit of a second straight minor premiership aided by the six tries to two triumph.
The defeat cost the Sea Eagles a chance to join the top four and they remain in seventh place, ahead of Brisbane only via a superior for-and-against.
The refereeing performance added to the grave concern about the state of the NRL's officiating with both sides awarded dubious tries.
The Warriors are 6th.
