MELBOURNE, Australia — After a day of searingly-hot temperatures which raised complaints from players, top-seeded Rafael Nadal advanced to the second round of the Australian Open in relatively mild conditions. Nadal's Australian opponent Bernard Tomic, bothered from the start by a left leg injury, retired from the match after losing the first set 6-4. Some in the capacity crowd of 15,000 at Rod Laver Arena booed lustily when Tomic indicated he could not continue.
