Roger Federer and Rafael Nadal are now on par to win the Australian Open with at least one major sportsbook: Sportingbet.
Both players, with that site, are currently priced at +300 (3/1) and the gap between the two is pretty tight with all other sites our staff looked at.
Our recommendation however is to bet Novak Djokovic, who is still priced at +600 with Ladbrokes, to win the Australian Open as Nadal and Federer appear to have odds that are still too short based on how they have both looked post-US Open.
