Roddick Wins, Blake Bounced at Australian Open

"I think they're great the way they support him," Roddick said of Baghdatis' raucous Greek fan base in Melbourne. "They even came and tried to heckle me a little bit today at the end of my match (after Baghdatis had already won) and I said 'Man, you guys can't show your hand before the end of it.' But you know they are going to do everything they can to help their guy and that's the job of a good fan and they certainly are that. I'm going to expect the worst for me and I think it's easier when you know what you're in for, going into the match but you can definitely appreciate that kind of loyal and passionate fan support, even if it's not for you."

For Baghdatis it is his second consecutive fourth-round appearance in Melbourne.

"I like the surface here, I won the juniors here and every time I come here it feels great," Baghdatis said. "I love the atmosphere and the fans are helping me so much."

Not loving the atmosphere, or his consistent baseline opponent, was No. 20-seeded American James Blake who was knocked out by No. 16-seeded Spaniard Tommy Robredo 6-3, 6-4, 6-4.

No. 8 seed Gaston Gaudio was also ousted and outlasted in over four hours in the brutal heat and wind, falling to 33-year-old Frenchman Fabrice "The Magician" Santoro 6-3, 6-2, 5-7, 1-6, 6-4.

"It is always tough to play against Fabrice," Gaudio said earlier. "I love to watch him. I think he is one of the most talented players I have ever seen. But to play against him is very tough, almost annoying. You never know what shot he is going to play. It can drive you crazy."

Other winners were (4) David Nalbandian (d. (26) Nieminen in four), (7) Ivan Ljubicic (d. (31) F.Lopez, bagel in the third), (10) Thomas Johansson (d. Simon), and (11) David Ferrer (d. (18) Ancic).

On tap for Saturday are Haas vs. the Aussie Luczak, (1) Federer vs. (30) Max "The Beast" Mirnyi, (6) Guillermo "El Mago" Coria vs. (25) Grosjean, (15) Ferrero vs. (21) Kiefer, (12) Dominik "The Dominator" Hrbaty vs. (23) Andreev, (5) Davydenko vs. the Aussie Healey, Chela vs. Vliegen, and Mathieu vs. Horna.

In doubles highlights look for (5) Fabrice "The Magician" Santoro/Zimonjic vs. Spaniards Feliciano "F-Lo" Lopez/Fernando "Hot Sauce" Verdasco, (11) Bhupathi/Moodie vs. Frenchmen Clement/Llodra, Austrians (12) Knowle/Jurgen "Tuna" Melzer vs. Belgians Xavier "X-Man" Malisse/Olivier "The Roach" Rochus, and (8) Aspelin/Perry vs. Spaniards Ferrer/Vicente.
