Most of the top players in the field have made it through the opening rounds of the French Open unscathed. However, things will get tougher beginning on Friday.
To this point, the only highly seeded player on the men's side to fall is Tomas Berdych. The No. 5 seed lost to Gael Monfils in the first round while Li Na and Caroline Wozniacki were the two top-10 women to lose.
The majority of favorites, however, are still alive.
After Round 3, there will likely be a few more players added to this list. Anything can happen in what is a competitive field, but these top seeds should especially be on upset alert.
No. 1 Novak Djokovic
There are few competitors in tennis who know what it takes to beat Novak Djokovic, especially in recent years. However, Grigor Dimitrov is one of those players.
The Bulgarian youngster defeated the No. 1 player in the world in the second round at the Madrid Open. He displayed a great serving ability with his 13 aces in the match.
Djokovic also lost relatively early at the Rome Masters to Tomas Berdych, showing that he is clearly less than 100 percent at this point of the year.
So far at Roland Garros, the men's top seed struggled a bit against David Goffin, but he had a much easier time against Guido Pella, as Djokovic was as good as ever with his strong serves and ability to end rallies.
Djokovic will need to continue his level of play against Dimitrov to avoid losing early at this prestigious event.
No. 6 Jo-Wilfried Tsonga
Much to the delight of the French home crowd, Jo-Wilfried Tsonga has cruised through his first two matches. He has only had one real tough set, which he won in a tiebreaker against Jarkko Nieminen
The rest of the two matches were easygoing, as he charged the net consistently and gave his opponents no chance.
It will not be as easy for Tsonga in the third round, however, with Jeremy Chardy looming after two successful rounds himself. This matchup will take away a great deal of the home crowd advantage with both players claiming France as their residence.
Of course, Chardy is plenty talented himself, especially when he is accurate with his serve. He has won 74 percent of points on his first serve but only 48 percent on his second serve.
If he can get this first serve in play, Tsonga will be in serious trouble.
No. 8 Angelique Kerber
As good as Serena Williams has performed lately, the women's draw is relatively wide open. Few players have displayed a great deal of consistency in Grand Slam tournaments, especially at the French Open.
This gives Angelique Kerber as good of a chance as anyone to make a run at a title.
However, she will have a tough battle in the third round where she must face Varvara Lepchenko. The American has been incredibly efficient in the early matches, winning each in straight sets.
Only once has Lepchenko allowed her opponent to win more than two games in a set. She is also one of the better returners on the tour and knows how to break her opponent.
Kerber has high hopes this week, but she cannot look past her next matchup.
