Nishikori works late to reach U.S. Open quarterfinals

That's the way, Kei-san ! Taking down the 5-seed is no small task ! Go get 'em ! Next ? The Aussie Open champ, Stan "The Man" Wawrinka ! You can do it ! Ganbarre, Kei-san !

Excellent result!

There is no doubt that Nishikori is a great tennis player.

Wow! Beating Milos Raonic is really really impressive. Ganbare Kei-chan.
