As the Bulls came charging down Seiffert Oval off the kick chase there was one thing on the Canberra Raiders under-20s' minds: Gungahlin are here to play. Having been pushed over the tryline and forced to defend back-to-back sets in the opening minutes, Ash Barnes implored his side to just dig deep. And they responded with a 66-point rout. The young Green Machine claimed the biggest grand final win in Canberra Raiders Cup history on Sunday, thrashing the Bulls 66-10 with a 13-try blitz. A 46-0 first-half shutout saw the Raiders smash the previous record held by the West Belconnen Warriors, who beat the Queanbeyan Blues 44-10 in 1998.
