Neither of the two players are playing at the same high levels as they displayed when they took their Wimbledon titles. Williams however has managed to mantain a degree of consistency in her tennis while Mauresmo has fallen to her current 33rd in the WTA Tour rankings.

Mauresmo also lost in her home country's grand slam, the French Open earlier this month in the second round to 81st ranked Virginia Ruano Pascual of Spain.

Roger Federer (SUI)[1] v. Marc Gicquel (FRA)
Federer has won over 60 grasscourt matches in a rowand is very unlikely to lose to Gicquel today.
Winner: Federer

Amelie Mauresmo (FRA)[29] v. Serena Williams (USA)[6]
Mauresmo is not playing anywhere near her best tennis and is only a shadow of the player who reached the number one ranking.
Winner: Williams

Lleyton Hewitt (AUS)[20] v. Simone Bolelli (ITA)
2002 Wimbledon champion Lleyton Hewitt of Australia should take advantage of a open draw until his fourth round meeting with world number one Roger Federer of Switzerland.
Winner: Hewitt

Ana Ivanovic (SRB)[1] v. Jie Zheng (CHN)
Ivanovic needed some help from Dechy of France and the net in her prior round in order to win in three very close sets, but she should display a better game today after that wakeup call.
Winner: Ivanovic

Marat Safin (RUS) v. Andreas Seppi (ITA)[29]
Safin's powerful serve and groundstrokes served him well in his upset of Australian Open champion Novak Djokovic of Serbia and should hand him another victory today.
Winner: Safin

Svetlana Kuznetsova (RUS)[4] v. Barbora Zahlavova Strycova (CZE)
2004 US Open winner Kuznetsova of Russia could cruise until her quarterfinal meeting with Serena Williams.
Winner: Kuznetsova
