It's a shame. This guy is also very talented, but the disease and injuries really ruined his career. A retirement at the age of 26 speaks for itself.
Yeah, he really is another great player from ex-Yugoslavia. I just wish Slovenia had a great player too. Croats were always strong in tennis (Ljubicic, Cilic, Karlovic), Serbs have Djokovic of course, but also Troicki, Tipsarevic and for doubles - Zimonjic. Raonic is Canadian but he was born in Montenegro so he is a little bit "theirs" too.
Our Kavcic is currently ranked "only" 87.
