Rampant Broncos batter Bulldogs

Updated: 

James Roberts scored two second-half tries as Brisbane Broncos ran riot in a 42-12 thrashing of Canterbury Bulldogs to stay on course for a top-four spot in the NRL.

The Bulldogs' finals hopes were dealt a major blow at Suncorp Stadium, where Wayne Bennett's side ran in seven tries on Thursday to move up to second place.

Canterbury took an early lead when Marcelo Montoya rounded off a slick move by diving over for the first try, but the Broncos came roaring back to open up a 16-6 half-time advantage.

Tautau Moga burst away for their first four-pointer after Andrew McCullough threw a dummy to make a break and Ben Hunt added a superb solo try before Jordan Kahu finished a brilliant move just before the interval.

It was one-way traffic in the second half, as Kodi Nikorima and Josh McGuire went over in quick succession prior to the dangerous Roberts showing a rapid turn of foot to help himself to a clinical double.

Kahu landed a penalty and six conversions in a one-sided encounter, with Chase Stanley's try late on offering little consolation for the heavily-beaten Bulldogs.
