The world's most prestigious tennis tournament is celebrating a major milestone this year, with another strong field of men and women contenders.
On the ladies side of the draw, world No. 1 Caroline Wozniacki of Denmark has been awarded the tournament's top seed, followed by Vera Zvonareva of Russia. Zvonareva defeated American Alison Riske, 6-0, 3-6, 6-3, in Monday's first round.
Serena, the tourney's seventh seed, is trying to come back from injury and illness since her fourth Wimbledon singles championship early last July.
Serbia's Novak Djokovic, who had his 43-match winning streak ended by Roger Federer at the French Open, is seeded second. Federer, the former six-time Wimbledon men's champion, is the third seed in the men's draw.
