Novak Djokovic and Rafael Nadal are both in New York for the US Open next week. The odds of them choosing the same nighttime activity had to be pretty low. Yet somehow, they both ended up backstage at Mamma Mia! on Tuesday night. The US Open starts on Monday when we’ll see just how musical theater comes into play. Andy Roddick and Roger Federer have been doing nothing but sitting front row for The Book of Mormon and practicing tennis all week. These girls better be ready for the fight of their lives!
