Highlights - Stosur pulls off Dementieva shock
Fourth seed Elena Dementieva saw her French Open campaign come to an end with a shock 6-3 4-6 6-1 defeat by Samantha Stosur in round three.
The reigning Olympic champion was broken twice to lose the opening set but fought back to edge the second.
Dementieva's problems on serve helped Stosur go 4-0 up in the decider and the 30th seed broke at 5-1 for the match.
Second seed Serena Williams almost followed Dementieva out, but beat Maria Jose Martinez Sanchez 4-6 6-3 6-4.
Martinez Sanchez took an ill-tempered opening set after breaking in the fifth game with a controversial shot which appeared to have bounced off her arm.
Annoyed with the call, Williams went on to level the contest and her opponent eventually ran out of steam, bowing out after two hours 11 minutes on the first match point.
I'm far away from being in good shape - it's a very physical game when it comes to the clay courts so it's not good for me
"The ball did touch her 100% on her arm," said Williams afterwards. "The rules of tennis is when the ball hits your body, then it's out of play. You lose a point automatically.
"So the ball hit her body, and therefore, she should have lost the point instead of cheating."
Standing between the 2002 champion and a place in the last eight is Canada's Aleksandra Wozniak, who beat Lourdes Dominguez Lino in three sets.
Tenth seed Caroline Wozniacki of Denmark went out to unseeded Sorana Cirstea in a late-running match on Court One, with the Romanian taking it 7-6 (7-3) 7-5 after Wozniacki needed a medical time-out for a back problem when just two points from defeat.
Cirstea next plays Jelena Jankovic, whoovercame Jarmila Groth 6-1 6-1, while Svetlana Kuznetsova claimed a 6-1 6-3 victory over Melinda Czink.
Fifth seed Jankovic dropped serve in the opening game against Groth but dominated the rest of the set.
Jankovic, chasing a maiden Grand Slam title, was broken again in the sixth game of the second but the Serb's benevolence was short-lived and she claimed victory when 73rd-ranked Groth netted a forehand.
The former world number one has dropped just 10 games all tournament.
"I cruised through the match and did my job, did what I had to do in order to win," said Jankovic.
Seventh seed Kuznetsova enjoyed a near-faultless first set, which she won in 22 minutes by taking two out of two break points and facing none on her own serve.
The Russian broke her Hungarian opponent in games three and nine of the second set to wrap up the win.
"I was just doing my thing," said Kuznetsova, the 2006 runner-up.
"I was depending on myself and not on her. I think I controlled all of the match."
Kuznetsova faces Agnieszka Radwanska in the last 16 after the 12th seed from Poland saw off Kateryna Bondarenko 6-2 6-4.
Stosur, a former doubles champion at Roland Garros, is into the fourth round for the first time and now plays Virginie Razzano after she ousted Tathiana Garbin 7-5 7-5.
The Australian converted seven of her 15 break points against Dementieva, the 2004 runner-up at Roland Garros.
"I just feel I'm far away from being in good shape," said Dementieva, who became the second big name to fall after third seed Venus Williams went out on Friday.
"It's a very physical game when it comes to the clay courts, so it's not good for me. Just too many unforced errors and not enough power from me.
"So I hope I have enough time to get ready for Wimbledon and physically feel much better than this week."
Stosur said: "I came out playing well. I wasn't too nervous and I tried the handle the wind as best as I could.
"Even though I lost the second set, I knew I had to keep plugging away in the third.
"As that match went on I knew I could get there, because I was playing well enough and was handling the conditions and everything maybe a little bit better than her."
Also through to the fourth round is ninth seed Victoria Azarenka, who finished off her third round match against Carla Suarez Navarro, which started on Friday evening, with a 5-7 7-5 6-2 win.
