TAB has opened up the Sydney Roosters as hot favourites to claim back-to-back NRL Grand Finals.

Off the back of their epic Preliminary Final win over Melbourne this evening at the SCG, TAB has the chooks as $1.35 favourites while Canberra are $3.25 outsiders for the Grand Final on Sunday week.

The line has been set at 8.5 points.

One TAB customer is eyeing off a potential collect of $25,200 after having a big bet on the AFL/NRL Grand Final Quinella. The punter outlaid $8,000 @ $3.15 on the Richmond / Roosters double and is halfway home after the Tigers cruised to victory this afternoon in the AFL decider.
