Having claimed six prized scalps already this summer, in-form Aussie hopes Bernard Tomic and Lleyton Hewitt are the unseeded players to avoid at the Australian Open draw today.
Every player in the men's draw, including world No1 and two-time defending champion Novak Djokovic, will be looking to steer clear of the resurgent Australian pair as they threaten to cause some early-round damage once again at Melbourne Park.
Tomic has made a mockery of his No64 ranking over the past fortnight, taking down four of the Open's top 32 seeds during his hot summer run - Djokovic (1), Tommy Haas (20) and Andreas Seppi (22) at the Hopman Cup in Perth and Florian Mayer (26) at the Sydney International.
And despite his lowly No82 ranking, Hewitt has already accounted for Tomas Berdych, the Open's fifth seed, and 14th-seed Milos Raonic at the Kooyong Classic in Melbourne.
The top 32 men's and women's seeds are guaranteed a seed-free passage through to the third round at the Australian Open.
