LONDON -- Japan's Kei Nishikori says he is "almost 100 percent perfect" health-wise heading into Wimbledon.
The 10th-seeded Nishikori has been hampered by a hip problem that he says Saturday contributed to a first-round loss at the French Open.
But the first Japanese man to be ranked in the top 10 says his run to the semifinals on grass at Halle, Germany, last week showed he is fit.
Wimbledon is the only Grand Slam tournament where Nishikori has not made it to at least the fourth round. He lost in the third round each of the last two years at the All England Club, and in the first round in his other three appearances.
Says Nishikori: "Actually never did well on grass court yet, so hopefully I can do better this year."
