Amelie Mauresmo had to have her appendix removed in mid-April. She's recovered a great deal, but still, she's not ready enough to compete in J&S Cup, which takes place in Warsaw next week.
The French number 1 decided to make a comeback in Berlin, at Qatar Telecom German Open, a $1,340,000 tournament which starts on May 7. After Berlin, Mauresmo will play in Rome, and after Rome, she'll have intensive training to prepare for the second Grand Slam of the year, Roland Garros.
