The Williams sisters could meet again in the Wimbledon final this year.
Serena, the two-time defending champion, and Venus, a two-time winner, were placed in opposite halves of the women's draw yesterday -- setting up a shot at a third straight final featuring the siblings.
The top-seeded Serena opens with China's Jie Zheng. Her first tough match could come against No. 7 Jennifer Capriati in the quarterfinals -- Capriati beat Serena at the French Open last month.
If she gets past that, Serena -- without a major since last Wimbledon -- could end up facing No. 4 Amelie Mauresmo of France.
Venus, on the same side with French Open champion and No. 2 Anastasia Myskina, starts against Switzerland's Marie-Gayanay Mikaelian, and could meet No. 5 Lindsay Davenport in the quarters.
On the men's side, top-seeded defending champion Roger Federer has 2001 winner Lleyton Hewitt in his half, while No. 2 Andy Roddick has perennial British contender Tim Henman in his section.
The grass-court Grand Slam tournament will begin Monday and end July 4.
Nine-time champion Martina Navratilova, who received a wild card to play singles, has a first-round match against Catalina Castano of Colombia. In the second round, the 47-year-old would meet either Jelena Dokic or Gisela Dulko.
