She hasn’t won the French since 2003 and hasn’t made it as far as the semis since 2004. She has played just two tournaments since the Australian Open, losing in the semis to Jankovic in Rome and in the second round to Nadia Petrova in Madrid. Still, with no clear cut challenger, Serena remains the favorite. She almost always finds an extra gear for the Slams. RESULT: Lost to Samantha Stosur in quarterfinals

The Belgian has had an up-and-down return to tennis, finally winning her first title in Stuttgart on the clay but then suffering an early defeat in Madrid. A four-time champion at Roland Garros, Henin has the best French Open resume of anyone in the field. RESULT: Lost in fourth round to Samantha Stosur

Every time you think Jankovic is fading from the conversation, she comes roaring back. It’s been a good spring for the Serbian, who won Indian Wells and beat Yanina Wickmayer and both Williams sisters on the way to the Rome final. A Roland Garros semifinalist in 2007 and 2008, she’s shown she has it what takes to make a deep run in Paris. RESULT: Lost to Samantha Stosur in semifinals

The surprise Italian Open winner shot up to No. 19 in the world after the conquest in Rome. She took down Wozniacki, Jelena Jankovic and Ana Ivanovic on the way to her third career tournament win — all on clay. She’s probably not a contender at Roland Garros, but no top player is going to want to see her in their portion of the draw. RESULT: Lost in first round to Akgul Amanmuradova

Much like Azarenka, the 2009 U.S. Open finalist is a top-tier player who has struggled on the clay this season. She won the Ponte Vedra title without beating anyone ranked higher than No. 30 and has since lost in the first round in Stuttgart and the second round in Rome and Madrid. The Dane seems poised to disappoint. RESULT: Lost in quarterfinals to Francesca Schiavone

The French Open has never been her tournament, save for a run to the final in 2002. Venus has been ousted in the third round three straight years at Roland Garros, and there’s little to suggest she’s headed for better things in 2010 — she lost 6-0, 6-1 to Jelena Jankovic in the quarterfinals of her first clay event of the year in Rome. RESULT: Lost in fourth round to Nadia Petrova

The defending champion at Roland Garros, Kuznetsova certainly has all the tools to be a contender once again. What then to make of her 2010 season? A second-round loss in Stuttgart and first-round losses in Rome and Madrid paint an ominous picture of her chances — she was the champion in Stuttgart and the finalist in Rome before last year’s triumph. RESULT: Lost in third round to Maria Kirilenko

The Belarusian continues to be the best player on tour to have never reached the final four at a Grand Slam. She was a quarterfinalist at Roland Garros last year — and at the Aussie this year — but her clay stretch has been forgetful. She hasn’t made it far enough in any of her four events to run into another top 10 player. RESULT: Lost in first round to Gisela Dulko

The question has now changed from “When will she be back?” to “Will she ever be back?” Sharapova’s injury concerns are clearly hampering her game. She followed a first-round exit at the Aussie Open this year with a title win in Memphis before injuring her arm at Indian Wells. She returned at Madrid last week only to suffer a first-round exit. The one trophy she needs to complete her Career Slam seems certain to evade her grasp again. RESULT: Lost in third round to Justine Henin

What a mess. Poor Safina can’t get her game anywhere close to on track. After ending 2009 with injury concerns, few can forget the former world No. 1's painful physical breakdown at the Australian Open. She missed the American hard-court season and has won just one match in three tournaments on the clay through the Madrid Masters. A third-straight run to the French Open final is a pipe dream. RESULT: Lost in first round to Kimiko Date Krumm
