Doing the damage were (6)
Guillermo Canas (d. (1) Nalbandian in three), unseeded Italian
Davide Sanguinetti (d. (2) Massu), (8) Feliciano "F-Lo" Lopez (d. (3) Schuettler), and unseeded German
Tommy Haas (d. Robby "Baby Courier" Ginepri in three).
"I was playing very good (earlier), I don't know what happened today," said a flustered Massu. "At this moment I am very angry."
Saturday's match-ups are (6) Canas vs. Haas (Canas leads meetings 2-1), and (8) F-Lo vs. Sanguinetti (first meeting).
