PARIS- Former champion Li Na, the second-seeded Chinese superstar and Australian Open winner, has been sensationally dumped out of the French Open in the first round, beaten by a tearful Kristina Mladenovic.
Li, the 2011 champion, went down 7-5 3-6 6-1 to the 103rd-ranked blonde Frenchwoman, the Roland Garros junior champion in 2009 to suffer her first opening round defeat in Paris in eight visits.
Mladenovic, who was Australian Open mixed doubles champion this year with Daniel Nestor, goes on to face American Alison Riske.
"It didn't matter who I was playing today I still would have lost. The problem was myself. I threw myself away," said Li.
Mladenovic, who was 36 in the world last August, was in tears after her victory, her third over a top 10 player.
"I don't have the words to describe what just happened. To beat the world number two in the first round at Roland Garros, it's incredible," she said
Ex-world number one Caroline Wozniacki, the 13th seeded Dane, lost 7-6 (7/5) 4-6 6-2 to Belgium's Yanina Wickmayer in her first outing since her romance with superstar golfer Rory McIlroy ended.
"I was not prepared for this, it all came as a bit of a shock," Wozniacki said, adding that she had to move on from the breakup.
Also making an early exit was Bulgarian men's 11th seed Grigor Dimitrov who lost 6-4 7-5 7-6 (7/4) to giant Croat Ivo Karlovic.
The 35 year old Karlovic, whose last win in Paris was seven years ago, next faces Austria's Andreas Haider-Maurer.
Spanish fifth seed David Ferrer, last year's runner up to Rafael Nadal, began his 12th Roland Garros by coasting past Igor Sijsling of the Netherlands, 6-4 6-3 6-1.
Ferrer, 32, has reached the quarter-finals or better at his last nine majors and goes on to play Simone Bolelli of Italy.
