SIGHTING: Andy Roddick joins shirtless brigade during Kooyong Classic

Our lucky day: So we found more gratuitous shirtless shots - this time of Andy Roddick, who dropped his cute Lacoste tennis duds for a practice session during the Kooyong Classic.

The defending champion reached the final today by easily defeating another shirtless wonder, Russia's Marat Safin 6-3, 6-3.

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."

SIGHTING: David Nalbandian looks primed for Aussie Open challenge

Spoiler alert? Former Wimbledon finalist and current Roger Federer nemesis David Nalbandian was spotted training in Melbourne recently for the Australian Open.

From these photos the man with the lethal double-fisted backhand looks in great shape to spoil Fed's chances at the first Grand Slam of the year. After all, he did beat the World No. 1 the last 2 times they played - in Master Series events no less (not to mention 2 straight defeats of World No. 2 Rafael Nadal as well.)

The Argentine will also be part of the elite 8-man field at the Kooyong Classic this week. Unfortunately, we won't get to see a rematch between the two just yet as Fed pulled out of Kooyong with a severe stomach virus. More to look forward to in Melbourne, we suppose...
