WIMBLEDON, England -- Defending champion Serena Williams was bumped up to No. 7 in the Wimbledon seedings -- 19 places above her world ranking -- on Wednesday, a position that will allow her to avoid playing the highest-ranked players until at least the quarterfinals.
Williams won her 13th Grand Slam title last year at the All England Club but was injured when she stepped on broken glass at a restaurant in July and needed two foot surgeries. She later had blood clots on her lungs and missed nearly a year of competition.
She returned Tuesday at Eastbourne, coming back from a set down to defeat Tsvetana Pironkova 1-6, 6-3, 6-4. But her run at that warm-up tournament was short-lived, as she was beaten Wednesday by Vera Zvonareva 3-6, 7-6 (5), 7-5.
Williams was originally seeded No. 8, but the withdrawal of second-seeded Kim Clijsters moved the rest of the field up one spot.
"Listen, I don't ask for much. I would have been happy with 25, because I'm going to be in there fighting for every point and for everything," Williams said. "It's doesn't matter where I'm seeded. I'm just going to give it 200 percent like everyone else in the draw."
Wimbledon starts Monday. The draw is scheduled for Friday.
Federer and Nadal have combined for the past eight titles at the All England Club.
For Federer, it's the first time he's been outside the top two seedings at Wimbledon since 2003, the year he won the first of five straight titles at the grass-court Grand Slam.
Since her injury, Williams has dropped to No. 26 in the WTA rankings. If Wimbledon organizers had seeded her according to her ranking, the four-time Wimbledon champion could have come up against a top player in the third round.
Her sister Venus, a five-time Wimbledon champion, was seeded No. 24. She has dropped to 33rd in the rankings since missing most of this season with a hip injury. She also returned to action this week at Eastbourne, with two wins so far.
"The seeding order follows the WTA ranking list, except where in the opinion of the committee, a change is necessary to produce a balanced draw," Wimbledon organizers said. "This reflects the balance between their proven records and also their lack of competitive play in the past 12 months."
The sisters have combined to win nine of the past 11 titles at the All England Club.
"I just want to be in the draw," said Venus, who beat Ana Ivanovic 6-3, 6-2 on Wednesday to reach the quarterfinals at Eastbourne. "I'm still in this tournament so that's pretty much my focus. For me, the seedings are not a big deal."
At the top of the women's seeding list is Caroline Wozniacki, ranked No. 1 in the world. She had been followed by Australian Open champion Clijsters at No. 2, but the Belgian withdrew from Wimbledon later Wednesday after she injured her right foot Tuesday at the Unicef Open in the Netherlands.
"I'm very disappointed to have to withdraw from Wimbledon after injuring my foot again," Clijsters said. "At this moment I feel frustrated that it has to happen now before one of my favorite tournaments. I've always enjoyed being a part of the Wimbledon atmosphere but I have no other choice now but to rest, recover and to not play tennis for a few weeks."
Clijsters has won three major titles since coming out of retirement in 2009. She hurt her right ankle while dancing at her cousin's wedding in April. She played at the French Open but lost in the second round.
