Who has Venus partnered other than Serena? All I can think of is Wozniacki but that was an exhibition. Also Raymond in Fed Cup.
Wozniacki in 2008 Doha (you're thinking of Hong Kong, which they played too but it doesn't matter here), 2007 Fed Cup with Lisa, 2005 Fed Cup dead rubber with Morariu. Then Huber at this year's Fed Cup, but that was a win and Rubin at 2004 Olympics but that was a 3 set loss to eventual Gold Medalists Li/Sun.
Venus, THE QUEEN Serena THE WARRIOR
Comeback you two to your previous level and dominate the tour once again, and this time... for a long long time
Miss you Monica Wynne Angie Anna Chakvy Marion
