Re: US Fed Cup team: Oudin, Glatch, Huber and Mattek-Sands
Serena and Venus aren't on the team because they elected not to play. I'm sure they were asked and if they were willing to play they would be in here over a mixture of rookies and journeywomen.
They, especially Serena, normally don't play Fed Cup often because of already having their preferred tournament load. It helps to cut down the wear and tear on their bodies. Unfortunately, for Serena's case she can't even play almost AT ALL without being injured. Venus has been more loyal than Serena, but has stated she regrets some of her commitment to certain ties.
Safarova and Vaidisova should be able to get through them especially indoors unless Mattek plays out of her mind which is unlikely since she is coming back from injury.
