The top eight seeds, including four-time champion Andy Roddick, have byes into the second round.

Another four-time champion, Lleyton Hewitt, received a wild card and is scheduled to face 2005 runner-up Ivo Karlovic in the first round.

Roddick and Hewitt will team up for doubles for the first time.
