Top players still alive in Melbourne

The Australian Open got underway this week, and so far there haven't been many notable upsets. Nadal, Federer, Djokovic, Murray, and Roddick all won their matches. Nadal and Murray will play their second-round matches while I'm sleeping tonight. Murray takes on Marcel Granollers, and Nadal plays a guy named Roko Karanusic, whom I've never heard of before. The other side of the draw is in the third round. Federer will play Marat Safin, which should be quite an interesting match. Those two have met in the Australian Open final before, with Federer winning, and in the semis the following year, with Safin winning.
