Novak Djokovic's early exit from Wimbledon was compounded by unlikely losses (singles and doubles) in Rio at the Olympic Games -- making 2016 unlike any in recent memory for the Serbian star. Is the World No. 1 still at the top of his game? Djokovic told the media that personal business cluttered his effort at the All England Club, and that it's since been cleared up. Rio was different. A wrist injury was a major factor. It's an injury that unfortunately required treatment again during his first round match at the US Open, a four-set victory over the dangerous Jerzy Janowicz.
It wasn't the wear and tear of the match either that made Djokovic call the trainer in New York: the star summoned medical treatment during the very first set. The injury is to his left wrist, so his forehand isn't affected. But Djokovic hits the preponderance of shots from the backhand side two-handed (though he employs a one-handed slice backhand also.) Djokovic has looked invincible for so long now that he looks uncomfortable out there with even the hint of vulnerability in the air. The defending champ takes on Jiri Vesely in the second round. It's a tough draw for the No. 1 seed. Vesely beat Djokovic in Monte Carlo earlier this year.The BEST SALES on Amazon NOW ]
