Rafael Nadal, Serena Williams made top-seeds at Australian Open

World number ones of both men and women's tennis, Rafael Nadal and Serena Williams, have reportedly been made the top seeds at the Australian Open, which begins on Jan 13 at Melbourne Park.

Defending champion and world number two Novak Djokovic have been made second-seeded, followed by Spaniard David Ferrer at third, Wimbledon champion Andy Murray at fourth, Argentine Juan Martin del Potro at fifth and 17-time Grand Slam champion Roger Federer at sixth.

According to Sport24, 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 report mentioned that the 32 seeds were only altered twice from the rankings, both because of injuries, with No 29-ranked Jurgen Melzer not playing due to a left shoulder injury and Maria Kirilenko, who would have been seeded 18th, having a left knee injury.
