Nadal Advances in Rome as Almagro Quits

Rafael Nadal advanced to the Rome Masters third round on Wednesday as fellow Spaniard Nicolas Almagro was forced to retire with a left knee injury.

Almagro, a three-time French Open quarter-finalist -- he lost all three to Nadal -- was unable to continue after 24 minutes while trailing his compatriot 3-0 in the first set.
