Paris, June 1

American teen Sloane Stephens and Maria Sharapova advanced on Friday, while Ana Ivanovic lost in the third round of the French Open.

Stephens reached the fourth round by beating Mathilde Johansson of France 6-3, 6-2. Of the eight teenagers in this year’s draw, the 19-year-old Stephens was the only one to reach the third round.

The second-seeded Sharapova defeated Ayumi Morita of Japan 6-1, 6-1 in a match postponed a day by the marathon contest between American John Isner and Frenchman Paul-Henri Mathieu.

Sharapova has won three major titles in her career, but she still needs to win at Roland Garros to complete a career Grand Slam.

Ivanovic fell to Sara Errani of Italy 1-6, 7-5, 6-3.

The 13th-seeded Ivanovic, a former top-ranked player who won the French Open title in 2008, committed 37 of her 40 unforced errors in the final two sets. Errani had only 18.

‘’In the third set I was creating a lot of opportunities and missing a lot of easy, easy finishing balls,’’ Ivanovic said. ‘’That’s something that I’m not really happy about.’’

Two days after eliminating Venus Williams from the French Open, third-seeded Agnieszka Radwanska was routed by 2009 champion Svetlana Kuznetsova 6-1, 6-2.

She didn’t look anything like the player who overwhelmed seven-time Grand Slam champion Williams in straight sets on Wednesday.

Radwanska has been having a stellar year on tour, winning three titles and moving up to a career-high No. 3 ranking last month. But she is the only player in the top 10 that has never reached a Grand Slam semifinal.

Radwanska dropped to 3-10 against the Russian, including her only two losses in tournament finals.

Before Friday’s match, Radwanska had been 38-7 in 2012, with six of those losses coming against top-ranked Victoria Azarenka.

Kuznetsova, who also won the U.S. Open in 2004, has struggled since winning the title at Roland Garros three years ago, only reaching one Grand Slam quarterfinal.

Later Friday, top-ranked Novak Djokovic and 2009 champion Roger Federer will play their third-round matches, while second-seeded Maria Sharapova will play in the second round.

Rafael Nadal has made a habit of celebrating at Roland Garros, and it’s not just because his June 3 birthday falls during the French Open.

This year, he is so focused on winning a record seventh French Open that he couldn’t even remember exactly when he will turn 26.

‘’When is my birthday?’’ Nadal said Thursday after being asked if he had anything special planned. ‘’I don’t know the day.’’

When you play like Nadal on clay, the only date to remember is the day of the French Open final.

This year, that’s exactly a week after his birthday.

‘’Difficult to celebrate ... when you are in the middle of the tournament, but sure, I’m going to go for dinner with the team,’’ Nadal said. ‘’I don’t know if some family going to come. I don’t know yet.’’

The second-seeded Nadal improved his French Open record to 47-1 on Thursday after beating Denis Istomin of Uzbekistan 6-2, 6-2, 6-0. If he wins five more matches, he will break the record of six French Open titles he shares with Bjorn Borg.

Nadal wasn’t the only record-breaker on court Thursday. Isner, who won the longest match in tennis history two years ago at Wimbledon, lost 18-16 in the fifth set of another marathon match.

Also, Andy Murray overcame back spasms to reach the third round, while fourth-seeded Petra Kvitova advanced in straight sets.

Kevin Anderson’s hopes of becoming the first South African man to reach the last 16 of a Grand Slam for nine years were shattered by Czech seventh seed Tomas Berdych in a French Open slugfest on Friday.

The 31st seed from Johannesburg was attempting to match comptariot Wayne Ferreira who made the fourth round at the Australian Open in 2003.

But after taking a two sets to one lead, he ran out of steam in the final set, when he needed treatment on his left thigh at every changeover, and lost 6-4, 3-6, 6-7 (4/7), 6-4 6-4, eight minutes short of four hours.

Berdych, a semi-finalist in Paris in 2010, will next take on either ninth seed Juan Martin Del Potro of Argentina or Marin Cilic of Croatia for a place in the quarter-finals.

The 26-year-old Czech had won both previous meetings with Anderson at this year’s Australian Open and on clay in Madrid last month without dropping a set and.

He looked on course for a comfortable win when he eased through the first set, but the 26-year-old South African matched him for big hitting in the second to level the tie.

Anderson had struggled to make this stage, having to save four match points in the first round against Rui Machado, but he played a more convincing tiebreak in the third which he sealed when Berdych dumped a simple smash into the net with the court at his mercy.

However, the Czech finished the fresher of the two, breaking in the ninth game of the fourth set and seventh of the decider to progress.

World number 98 Malek Jaziri wasted a great opportunity to become the first Tunisian man into a Grand Slam third round when he squandered three match points against Spanish 20th seed Marcel Granollers.

In a match held over from Tuesday, Granollers edged past Jaziri 7-6 (7/1), 3-6, 6-1, 3-6, 7-5 and will face France’s Paul-Henri Mathieu for a place in the last 16.

Later Friday, top seed Novak Djokovic faces French qualifier Nicolas Devilder, the world ranked 286, in a battle of the highest-ranked and the lowest-ranked players left in the draw.

Djokovic is bidding to become only the third man to hold all four Grand Slams at the same time and first since Rod Laver in 1969.

Third seed Roger Federer, fresh from setting a new Grand Slam match wins record of 234, tackles Nicolas Mahut while fifth seeded Frenchman Jo-Wilfried Tsonga faces Italy’s Fabio Fognini.
