Eurosport May 6 Clijsters calls time Clijsters in sad clay exitFormer world number one Kim Clijsters has retired with immediate effect. The 23-year-old Belgian, who is marrying American basketball player Brian Lynch in July, told her website: "It has been more than great. The rackets will be hung up." Clijsters, who had already pulled out of the French Open in May, had planned to play at Wimbledon. But the 2005 US Open champion lost her opening match at this week's Warsaw Cup to Julia Vakulenko and that seems to have hastened her decision. "After all my fantastic good-byes in Antwerp [where she lost in the final to Amelie Mauresmo], the fire had died out," Clijsters continued. "Every hour has been dedicated to my body, the difficulty of getting out of bed in the morning and heating up the muscles for an hour, the preparation for the marriage to Brian which is taking up more of my time … all of that made it very difficult to continue. "I would easily have been able to continue for a few months and to take part in the four most lucrative tournaments [the three grand slams and the WTA Tour championships]. The money is certainly important but not the most important thing in my life. Health and my private life are more important."
