What does it matter? They both are doing great. They are very young, 21 & 22. They have just started to dominate the tour. This is Serena first dominant year. Venus had 2 years when she dominated the tour. Let's see how consistant they will be in the future. Can they be like Graf or Navatolova & really rule the WTA for 5 or more years, let's see. I think Venus knows she has to up her level next year. Just like Serena did this year. Kim, Davenport, Seles, & Capriati, will have something to say about that.
