These kinds of things always bring up some questions. Like was it on his first try? Or was it after multiple fails? Seems like any halfway decent ballplayer could do the same thing as long as the sword was sharp enough...they do it all the time with bats.
He is just hitting the ball with very sharp bat pitched into the strike zone.
It might be a different story if The Cuban Missile or The Ryan Express was trying to hit you in the chest with a 100 mph fastball.
