SIGHTING: Roger Federer back in action, preps for Aussie Open campaign

Back in action: Roger Federer, who pulled out of the Kooyong Classic with a stomach virus, looks to be in good physical shape based on these photos of a recent practice/fitness session in Melbourne. In fact, the World No. 1 has an opportunity to play some matches at Kooyong now that David Nalbandian, who we thought had a good chance of challenging Fed at the Australian Open, has pulled out of the tournament with back spasms.

According to tournament director Colin Stubs,

"[Federer] said he would like the match practice, [...] We can slot a match outside the format. Federer, (James) Blake, (Novak) Djokovic are not out of the equation for a fourth match outside the bracket."

For his part, the Swiss Stylist said,

"I hung around and I definitely think [the decision is] going to turn for the good and I'll be 100 per cent, really, before the (Australian Open) starts."
