VIDEO: Watch Kei Nishikori play tennis with a wooden sword

Kei Nishikori isn't as physically imposing as some of his top competitors, but it doesn't really matter when he's wielding a wooden sword on the court.

The world's fifth-ranked player recently channeled his inner sword master for a Nissan Cup Noodle commercial, slicing and dicing his way to aces and winners with an array of impressive shots. 

Nishikori's weapon of choice: a wooden sword made from a paddle in honor of historical Japanese sword master Miyamoto Musashi.

It's easy to beat a fictitious opponent, but Nishikori's sword-swinging ways have us eager to see his skills put to test in real life action.
