Jankovic retires at Hopman Cup

Jelena Jankovic played one game against Tatiana Golovin at the Hopman Cup, then, feeling a terrible pain in her right hamstring, called it quits, giving Golovin a 0-1 victory. Jankovic fans have to wonder whether this is the start of Jankovic's paying for playing way too many matches in 2007. Or it could just be one of those things, and Jankovic wisely retired, rather than risk being injured for the Australian Open.
