Dragons push NRL title claims with big win over Storm

St George Illawarra strengthened their National Rugby League title claims with an impressive 34-14 win over defending champions Melbourne Storm at home on Sunday.

The Dragons sit alone at the top of the standings with eight wins and one loss while the Storm cling to fourth place, with their back-to-back title hopes diminished by the significant loss.

While the Storm were left unhappy with some contentious officiating in the first half, they did themselves no favours with too many handling errors and forward passes.

Josh Addo-Carr scored all of Melbourne's three tries and now has nine tries in his past four games as he presses for NSW State of Origin selection.

The New Zealand Warriors stayed in second spot after a 26-4 victory over Wests Tigers but the win was overshadowed by injuries to Kiwi Test stars Shaun Johnson (leg), Issac Luke (shoulder) and Adam Blair (ankle).

Last season's beaten grand finalists the North Queensland Cowboys put their season back on track with a 26-20 win over Penrith in Bathurst.

South Sydney extended their winning streak over the Newcastle Knights to nine straight matches, leading from start to finish in a 36-18 victory in Newcastle.

The Sydney Roosters spoiled one of the biggest boilovers of the season as a desperate Manly went down 22-20 at Allianz Stadium on Sunday.

Just four weeks after fearing his season was over through injury, Andrew Fifita has confirmed his standing as one of the NRL's best front-rowers by inspiring Cronulla to a dramatic 22-20 defeat of Parramatta.

Fifita produced another demonstration of his raw power and endurance and played more than 70 minutes as Cronulla hung on for a heart stopping win.

A controversial last-minute penalty goal to Jamayne Isaako gave Brisbane a 22-20 win over Canterbury at Suncorp Stadium just when the match seemed destined for golden point extra time.

With five minutes left the Bulldogs led 20-14 before Joe Ofahengaue who scored a converted try for the Broncos.

With time almost up, Moses Mbye was penalised for pushing as he dived for a loose ball over his try-line. Mbye was sin-binned and Isaako kicked the easy penalty for victory.

The Canberra Raiders continued their resurgence by claiming their fourth win in five games as they thumped the Gold Coast Titans 32-18.
