There are those who call this "Ultimate Batting Practice" video a fake.  If so, it's a good fake.  If not, this guy needs to be called up to the big leagues.  Check it out after the break.

I don't have good enough eyes (or a sense of physics) to figure out if this is real or fake.  I just enjoyed it for what it is.  The player uses four pitchback screens to keep hitting the ball over and over.  Check it out and let us know if you think it is real or fake.
