London calling for tired Nishikori

Kei Nishikori admits his body is hurting after a tumultuous season that has seen him establish himself as a potential Grand Slam winner, but he has one last mountain to climb.

That will come in London in seven days' time when the speedy Japanese star becomes the first Asian-born player to contest the prestigious ATP World Tour Finals, better known as the Masters of men's tennis.

Nishikori, who reached the final of the US Open in September, where he lost to Marin Cilic, made sure of his ticket to London on Friday when he defeated David Ferrer in the Paris Masters quarterfinals.
