The biggest names in tennis have been spending quite a bit of their time pre-U.S. Open running around the Big Apple satisfying media obligations and sponsor requests.
Roger Federer was off pouring champagne for celebrities earlier this week and Maria Sharapova sold candy before she withdrew from the tournament. Top-ranked Novak Djokovic and defending U.S. Open champions Andy Murray and Serena Williams have out and about too.
Here are some photos of their adventures:
