Both Serena Williams (foot) and Venus Williams (knee) are currently sidelined with injury, but both expect to be fit for the US Open, and both have now committed to represent the U.S. in the Fed Cup final, hosting Italy on Nov. 6-7, 2010, in San Diego, Calif.

Also on the team will be the players that got them to the final in 2010: Melanie Oudin, Bethanie Mattek-Sands and doubles specialist Liezel Huber. It remains to be seen where Oudin, Mattek-Sands and Huber will fit in, making some tough choices for U.S. captain Mary Joe Fernandez, since the Williams sisters excel in singles and are undefeated in Fed Cup doubles as a team.

Oudin, Mattek-Sands and Huber have led the U.S. squad to their second consecutive final, while the Palm Beach Gardens, Florida-based Williams sisters are making their first Fed Cup appearance since 2007.

“As captain, you always want to have your best players. I am very excited that Venus and Serena have made themselves available for the Fed Cup Final in San Diego,” said Fernandez, who last year in her rookie season as captain led the U.S. to the Fed Cup final for the first time since 2003. “Teaming Venus and Serena with Melanie, who continues to play an integral role in all of our Fed Cup matches, Bethanie, who has come through in decisive matches, and Liezel, who has been crucial in our doubles, we have one of the strongest line-ups in years. I strongly believe that this team can win the Fed Cup title on our home soil.”
