Marin Cilic  of Croatia, the 2014 US Open Men's Single champion, poses with his winning trophy at the Top of the Rock Observation Deck at Rockefeller Center in New York on September 9, 2014. Cilic hailed his maiden Grand Slam title at the US Open as a "miracle", 12 months after the towering Croatian was forced to watch the tournament from home, seething over a controversial doping ban.
