Serena has plenty of Olympic mixed options

Serena Williams says she has numerous options for her mixed doubles partner at the Olympics. "A girl loves to have choices," she told reporters at Fed Cup. "Obviously the Bryans are like the world's best doubles players. Andy [Roddick] and I are super, super close. Personally I love John [Isner]. You're not going to break the guy. It's an automatic I-don't-know-how-many games. I think it's so hard to choose. I don't know if you just throw everyone's name in a hat and figure out what happens next. Regardless, we want to do really well and take home a medal for the country. That's what it's all about."
