LONDON (AP)—Kim Clijsters and Caroline Wozniacki will begin their grass-court seasons at Eastbourne.

Clijsters celebrated her return to professional tennis following a two-year layoff with victory at the 2009 U.S. Open, where the 26-year-old Belgian beat Wozniacki in the final.

Clijsters, who won the title at Eastbourne in 2005, said the tournament would provide her with solid preparation for Wimbledon.

The fourth-ranked Wozniacki won her first grass-court title in Eastbourne last year. The 19-year-old Dane said she's looking forward to defending her title at Devonshire Park.

The event begins June 12.

LONDON (AP)—Rafael Nadal will return to Queen's this year after he was unable to defend his title at the grass-court tournament in 2009.

In 2008, Nadal was the first man to win at the French Open, Queen's Club and Wimbledon in the same year, but his persistent knee problems prevented him from defending his titles on grass at Queen's and Wimbledon last year.

He says there is now more motivation for him this year because he could not defend those titles. Nadal also says not being able to play at Wimbledon in 2009 was one of the toughest decisions of his career.

U.S. Open champion Juan Martin del Potro has also announced his intention to play in June at Queen's, the traditional men's warm-up event ahead of Wimbledon.
