Ivanovic finds form
French interest in the women's singles ended with Alizé Cornet's 6-2, 7-6 defeat by Elina Svitolina, who is through to her first quarter-final at a Grand Slam.
The 20-year-old from Ukraine will next face Ana Ivanovic, who is through to the last eight for the first time since she won the title here in 2008.
Ivanovic, who beat Russia's Ekaterina Makarova 7-5, 3-6, 6-1, appeared to have the world at her feet when she beat Dinara Safina in the 2008 final at the age of just 20, but it remains her only Grand Slam title.
The former world No 1 struggled for long periods in subsequent years: tomorrow's quarter-final will be only the third she has contested at Grand Slam level since her victory here.
"On the one hand it does feel like it's a different life," Ivanovic said after her victory. "On the other hand, I feel like time is really flying."
