Rome – 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.
