MELBOURNE, Australia (AP) 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.

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.
