The Swiss tennis great Roger Federer has ended local hopes in the singles at the Australian Open, beating rising Australian Bernard Tomic in straight sets to reach the fourth round in Melbourne.

Frenchman Jeremy Chardy provided a big upset, downing sixth seeded Argentine Juan Martin Del Potro 6-3 6-3 6-7 3-6 6-3.
