Defending champion departs —
Li Na was disappointed after suffering a surprise defeat in the fourth round of the French Open against Yaroslava Shvedova of Kazakhstan.

Shevdova celebrates —
World No. 142 Shvedova will next face either Czech fourth seed Petra Kvitova or Uzbekistan-born American Varvara Lepchenko after ending Li's title defense.

Sharapova's serve —
Maria Sharapova struggled with her serve against Klara Zakopalova, but reached the quarterfinals and can become the new world No. 1 by making it to the title match.

Czech canceled —
Zakopalova won their first encounter in 2003 when Sharapova was 15, but the Czech was unable to capitalize on the Russian's error-strewn performance in cold, windy conditions at Roland Garros.

Kanepi keeps winning —
Sharapova will next play Estonia's Kaia Kanepi (left) -- who followed up her win over former world No. 1 Caroline Wozniacki by beating unseeded Dutch player Arantxa Rus.

Kvitova on course —
Czech fourth seed Petra Kvitova reached the Paris quarterfinals for the first time, and the 2011 Wimbledon champion will next play Shvedova.
