Kei Nishikori is now extremely well known in the world of tennis. He is currently ranked world No. 6, and his relentless and persistent playing style is winning the hearts of many.

Back in his home country here in Japan, he's now a very popular figure. So much so that he now appears in several TV commercials. One of his most recent commercial appearance is for Nissin Cup Noodles.

In the commercial, he is playing "Space Invaders" in real life, where he has to use a fired-up tennis ball and racket to kill off the drone invaders!

Rows of drone invaders lie in front of Nishikori...

Although CG is used, Nishikori is shooting off REAL DRONES using a racket and a ball.

And Nishikori usually hits each drone in one go - hardly any misses! His shot is so accurate, the film crew were stunned!

He says he hasn't trained a lot with moving targets and it was enjoyable.

Really cool stage... and Nishikori's killed them all!

But wait, here comes "the big boss"...

Nishikori's got an answer - a red ball!!

And his signature posture - "Air K"

And the outcome? See the video in full!
