Kei Nishikori become the first man from Asia to secure a spot in a Grand Slam final, shocking top-ranked Novak Djokovic 6-4, 1-6, 7-6 (4), 6-3, in the U.S. Open.

He played two five-set marathons totaling eight and a half hours of tennis ahead of his match with Djokovic, but somehow looked as fresh as when he stepped on the court for his first match.

That’s not even the most impressive part.

During his match with Djokovic, Nishikori bounced his racket off of the court, AND WITHOUT LOOKING, caught it behind his back.

It was so effortless.

Did he mean to do that? Does he practice doing that? Can he do it at will? Was telekinesis or sorcery involved?

We won’t know until he does it again. In any case, you’ll probably keep looking at this gif on loop until he plays in the U.S. Open men’s singles final on Monday, September 8th at 5 p.m. ET on CBS.
