Elena Dementieva (RUS)[5] v. Patty Schnyder (SUI)[15]
Schnyder's crafty lefthanded groundstrokes cause player more problems on clay than hardcourts. Demetieva's game still lacks a powerful serve, but her groundstrokes are very consistent and aggressive. The recent gold medalist Dementieva should win in straight sets.
Prediction: Elena Dementieva

Tommy Robredo (ESP)[15] v. Novak Djokovic (SRB)[3]
Djokovic struggled in his prior match against a Croatian teenager and will need to take control of more points today and keep a lower error count.
Prediction: Novak Djokovic

Igor Andreev (RUS)[23] v. Roger Federer (SUI)[2]
Defending champion Federer doesn't look anywhere near as unstoppable now as he did a year ago, but on a harcourt, his allcourt game will be tough to beat. Andreev would need to play the match of his life to win.
Prediction: Roger Federer

Sybille Bammer (AUT)[29] v. Jelena Jankovic (SRB)[2]
Bammer's a good groundstroker, but Jankovic is queen of long baseline rallies. If Bammer can keep points short, she will have a chance. Jankovic however more likely will wear Bammer down with a mix of topspin and angles.
Prediction: Jelena Jankovic

Andy Roddick (USA)[8] v. Fernando Gonzalez (CHI)[11]
Roddick leads head to head. Both players will try to control the baseline with powerful forehands. Roddick should win if he can serve well and keep points shorter by for example attacking at the net.
Prediction: Andy Roddick
