BRUSSELS: Belgian star Kim Clijsters on Saturday slammed the “extremely harsh” sanctions imposed on compatriots Xavier Malisse and Yanina Wickmayer for missing drug tests. US Open semi-finalist Wickmayer and Malisse were on Thursday handed one-year bans by the Flemish Doping Tribunal for falling foul of doping regulations. Wickmayer, the world number 18, was suspended for failing to fulfill the controversial “whereabouts rule” while Malisse was also punished for missing a drug test. The suspensions on Malisse and Wickmayer run until November 4, 2010.
