Nadal, Wozniacki top seeds for Australian Open

Rafael Nadal and Caroline Wozniacki will top the seedings in the Australian Open, reflecting their No. 1 rankings in men's and women's tennis.

With seedings no longer done on organizers' discretion but purely on rankings, nine-time Grand Slam winner Nadal got the top spot Thursday, followed by Roger Federer, Novak Djokovic and Robin Soderling.

Vera Zvonareva is seeded No. 2 in the women's field, followed by, Kim Clijsters and Venus Williams.

The official draw will be made Friday at Melbourne Park.
