NEW YORK _ Novak Djokovic is the biggest of Big Three of men's tennis right now, having won the Australian Open and Wimbledon this season and one other ATP title. He fought off match points in the fifth set against Roger Federer at Wimbledon, solidifying his status as the greatest defensive player of all time. He lost last week in the semifinals at Cincinnati to Daniil Medvedev (more on him later). Djokovic is the No. 1 seed, the defending Open champ and a clear favorite as he goes for the second three-Slam season of his career.
