A career-threatening wrist injury left Japanese tennis' top male player fighting the fear that he may never again find himself among the world's best.
But after clawing his way back to the top, Kei Nishikori says he again has his sights set on a Grand Slam title.
"I was scared. The wrist is needed in tennis. I just kept thinking I would always have to play with this feeling of anxiety," Nishikori told Kyodo News in a recent interview in Tokyo.
