All of Agassi, Federer and Djokovic have won 7 out of the 9. Federer has never won M-C or Rome. Agassi didn't win M-C and Hamburg (3rd clay master). Djoko has never won M-C and Cincy. So far no one has won 8 out of the 9. I hope an active player will do it. (oops sorry I hadn't seen tennis pro's post. Sorry for the repeat.)
ETA: Nadal and Federer are the only 2 players who've won 5 different masters more than once. (Sampras, Agassi and Djoko: 4)
