Caroline Wozniacki [ Images ] has become the first Danish player to win the International Tennis Federation's (ITF) World Champion award, even though she has never won a Grand Slam.

Spain's Rafael Nadal [ Images ] took the men's award for the second time after winning three of the year's four Grand Slam titles.

"To be listed with all the former ITF World Champions is something I am really proud of," the 20-year-old Wozniacki, who in October became the first Dane to be ranked number one in the world, said in a statement.

"I had a great year in 2010 and I'm training hard to have an even better year in 2011."

Wozniacki, who knocked 13-times Grand Slam champion Serena Williams [ Images ] from the top spot, was a model of consistency this season, winning six titles.

Nadal's award capped a remarkable year for the 24-year-old who won the French Open [ Images ] for a fifth time, Wimbledon [ Images ] for the second time and then became the youngest man to complete a career Grand Slam when he won the US Open [ Images ] in September.

In doing so he regained the number one ranking from Roger Federer [ Images ]
