Novak Djokovic will be the first to say there's no such thing as an easy road to a Grand Slam title.
Still, when he looks around the locker room before his U.S. Open semifinal Saturday, it will be hard not to notice who's missing.
Roger Federer is gone. Rafael Nadal never showed up. Of the four men left at Flushing Meadows, only Djokovic has ever won a title at any of the sport's four majors.
That makes the Serb, who has five Grand Slam trophies and is defending champion at Flushing Meadows, the favorite heading into his semifinal against fourth-seeded David Ferrer. The winner goes against either Olympic gold medalist Andy Murray or Tomas Berdych, who will play in Saturday's first semifinal.
