Third-ranked Jelena Jankovic ended the run of defending champion Serena Williams today in the quarterfinals of the Australian Open, 6-3, 6-4, reports the AP. Williams, who had cruised through her first four matches without losing so much as a set, appeared sluggish chasing down shots and lost some speed on her normally overpowering serve, which Jankovic broke seven times.
"It's amazing to beat the defending champion," said the 22-year-old Serbian, "and in general a champion like Serena." Williams, an eight-time grand slam winner, seemed to gain some momentum after breaking her racket in the first set, but it didn't last as she eventually totaled 36 unforced errors. Jankovic will play either Justine Henin or Maria Sharapova in the semifinals.
