The Williams sisters have won seven of the last nine Wimbledon titles. The all-time series between the two is tied at 10-10, but Serena owns a 5-2 edge when those meetings are in Grand Slam finals. However, Venus defeated her sister in last year's Wimbledon final.
Serena is ranked No. 2 in the world and Venus No. 3, so a true seeding would have them meet in the semifinals. But Wimbledon officials put Venus in the top half of the draw, setting up a possible semifinal match between her and world No. 1 Dinara Safina.
If the seedings play out, Venus Williams would play world No. 6 Jelena Jankovic in the quarterfinals while Safina would draw fifth-seeded Svetlana Kuznetsova. Safina has lost twice since taking over the No. 1 ranking -- both times to Kuznetsova, including a rout in the finals of the French Open.
Serena Williams could find No. 8 Victoria Azarenka awaiting her in the quarters while the other part of the lower half of the draw would feature fourth-seeded Elena Dementieva against No. 7 Vera Zvonareva.
The Wimbledon championships begin Monday. The women's singles final is scheduled for July 4.
