It’s was almost a sad night in Paris for Novak Djokovic. The No.1-ranked tennis player in the world was nearly bounced out of the French Open, overcoming several match points, to beat Jo-Wilifried Tsonga in five sets. Djokovic has been bulldozing the competition in men’s tennis for the better part of the last year and is trying to complete the “Djokovic Slam”—holding all four major titles at the same time. No one has done that since 1969. Meanwhile, Roger Federer overcame a two-set deficit to beat Juan Martin del Potro.
