I was glad to do my first Facebook Live Q&A with fans and friends in August after a practice in Cincinnati at the Western & Southern Open. With the season over, I’m able to sit still for just a bit and share some follow-up answers to questions we didn’t get to then. Hope you enjoy!

  1. What is the most important shot in doubles, and which is your favorite?
    The serve and return are the most important, simply because they are hit more than any other shot. The serve has always been a strength of mine so I would say that is my favorite.
  2. Do you have a favorite match overall in your career?
    Playing in the Olympic mixed final was pretty special.Β  Just a surreal setting for me on a world stage
  3. What is your favorite singles victory you’ve had?
    Winning my first title at Newport [in 2009 over Sam Querrey, 6-7 (3), 7-5, 6-3] would have to be up there – a mixed feeling of satisfaction and relief.
  4. How is your preparation different for a tournament now that you have retired from singles?
    Training is more specific: more balance- and reflex-oriented work and less cardiovascular work.
  5. Do you miss the pro singles court yet?
    I definitely miss playing singles, as it was my sole focus for a really long time. In the same breath, I know it was the right decision so I am very much at peace with it.
  6. What do you like most about playing mixed doubles (with Venus Williams, Casey Dellacqua and others)?
    Mixed is a lot of fun. We do not get to play it very much so it’s nice to change it up. I just enjoy the different atmosphere it brings.
  7. What is the fastest serve you’ve ever hit?
    Hmm. I’m not quite sure, but my guess would be just above 130 mph [209.2 kph].
  8. Do you have a lucky charm that you carry with you?
    Not a specific charm to speak of, but if someone gives me something that is a lucky charm, I like to keep it with me if I can.
