Melbourne, Australia (AP)—As expected, No. 1-ranked Rafael Nadal and Serena Williams have been made the top seeds at the Australian Open which begins on Monday at Melbourne Park.

Defending champion Novak Djokovic is the No. 2-seeded man, followed by David Ferrer, Wimbledon champion Andy Murray, Juan Martin del Potro and 17-time Grand Slam champion Roger Federer at sixth.

On the women's side, defending champion Victoria Azarenka is No. 2, followed by Maria Sharapova, Li Na, Agnieszka Radwanska and former Wimbledon champion Petra Kvitova in sixth.

The 32 seeds were only altered twice from the rankings, both because of injuries. No. 29-ranked Jurgen Melzer is not playing due to a left shoulder injury and Maria Kirilenko, who would have been seeded 18th, has a left knee injury.
