Maria Sharapova, the defending champion in Paris, is about to open play on center court against Vitalia Diatchenko in a second-round match.
It will be interesting to see if the second-seeded Russian has recovered from the cold that had her coughing during her opening win against Kaia Kanepi.
Also, watch for the fans' reaction. Sharapova was booed as she left the court on Monday because she declined to do an on-court interview.
The good news for Sharapova and her sore throat comes from the weather, which should remain sunny, mild and dry the whole day.
