WIMBLEDON, England -- Defending men's champion Rafael Nadal and women's world No. 1 Caroline Wozniacki will be the top seeds at Wimbledon.
Play on the famed grass courts starts next Monday at the venerable All England Club.
Nadal, the men's top-ranked player, claimed his second Wimbledon title last year with a straight-set win over Tomas Berdych. The super Spaniard captured the French Open earlier this month for his 10th career Grand Slam crown and will head to Wimbledon off a quarterfinal loss to Jo-Wilfried Tsonga at the Queen's Club last week.
Wozniacki is on the other end of the spectrum, at least as far as Grand Slam play is concerned. She may be the top-ranked women's player, but has still yet to claim a major championship.
The 20-year-old has won five WTA titles this year, including last week's tournament in her native Denmark, but she was a semifinal loser at the Australian Open and fell in the third round of the French Open. Wimbledon has also been a struggle for Wozniacki, as she has never made it past the fourth round in her four visits to the London suburb.
Men's seedings went mostly according to the ATP rankings, although Wimbledon does have a formula that takes grass-court history into consideration.
Following Nadal in the men's draw are Australian Open champ Novak Djokovic, six-time Wimbledon winner Roger Federer, Queen's Club champ Andy Murray and Sweden's Robin Soderling. Berdych is the sixth seed and Spain's David Ferrer is seventh, opposite of their ATP rankings.
American Andy Roddick, Frenchman Gael Monfils and Mardy Fish of the U.S. round out the top 10. Roddick, who is 10th in the ATP rankings, earned a better seed based on his history at the AEC with a trio of runner-up finishes to Federer.
Another beneficiary of the Wimbledon formula is Tsonga, a quarterfinalist at the All England Club last year who finished as the runner-up to Murray at the recent Queen's Club event after his stunning win over Nadal. Ranked 19th in the world, he was moved up to 12th in the seedings.
The top seven in the women's rankings mirror the Wimbledon seedings, as Wozniacki is followed by Australian Open champ Kim Clijsters, 2010 Wimbledon runner-up Vera Zvonareva, French Open winner Li Na, Victoria Azarenka, 2004 Wimbledon champ Maria Sharapova and French Open runner-up Francesca Schiavone.
However, two-time defending women's champion Serena Williams was placed into the eighth seed despite a WTA ranking of 26. The four-time Wimbledon winner is playing at Eastbourne this week after nearly a year off because of health issues. She hadn't played competitively since winning the Wimbledon crown last year.
The 29-year-old American was sidelined for months after severing two tendons in her right foot, which wound up requiring a pair of surgeries, after stepping on some glass at a German restaurant. Then in February of this year, the 13-time Grand Slam champ underwent emergency treatment for a hematoma as a result of a pulmonary embolism -- a blood clot in her lungs.
Five-time Wimbledon champ Venus Williams earned the 24th seed despite being ranked 33rd in the world. She is also playing at Eastbourne this week after being sidelined since the Australian Open because of a hip injury.
The Williams sisters have combined to win nine of the last 11 Wimbledon titles.
Rounding out the top 10 women's seeds are Petra Kvitova of the Czech Republic and 2007 Wimbledon runner-up Marion Bartoli of France.
The draw for this year's Wimbledon championships will be revealed Friday.
