Clijsters says she's less than 50 percent

Kim Clijsters, who has been contending with an ankle injury, said after her loss to fellow Belgian Yanina Wickmayer in Miami that she is playing at "maybe not even 50 percent." Former No. 1 Clijsters, who will retire at the end of the year and has expressed a desire to win the two Grand Slam titles that have eluded her at Roland Garros and Wimbledon, says that she’s only scheduled to play Madrid and Rome as a lead ups to Paris, and may travel to Spain for a week of practice on clay.
