MELBOURNE, Australia (AP)
Novak Djokovic has heavily criticized Lance Armstrong's long-expected doping admissions, saying the seven-time Tour de France winner is a disgrace to cycling and ''should suffer for his lies.''
At the same time, the No. 1-ranked man in tennis says the drug testing program in his sport is ''good'' but concedes he hasn't had a blood test in six months.
Djokovic advanced to the fourth round at the Australian Open on Friday with a straight-sets win over Radek Stepanek, but most of his post-match news conference was devoted to comment on Armstrong's admissions in a U.S. television interview with Oprah Winfrey.
Djokovic says, ''I think it's a disgrace for the sport to have an athlete like this.''
