Caroline Wozniacki fires coach Sanchez

COPENHAGEN, Denmark -- Former top-ranked Caroline Wozniacki has fired coach Ricardo Sanchez of Spain after just two months.

Wozniacki's father, Piotr, told Wednesday's edition of Ekstra Bladet that his daughter didn't get "new impulses" from working with Sanchez.

The Spaniard was hired in early December, only to see Wozniacki fall to defending champion Kim Clijsters in the quarterfinals of the Australian Open and lose her No. 1 ranking.

Wozniacki remains without a Grand Slam title and is now ranked fourth.

Piotr Wozniacki will go back to coaching his daughter on his own.

Sanchez told the newspaper that he found it "impossible" to have a system with two coaches and that "Caroline only got confused."
