found?  I read the yahoo article where Daisuke Matsuzaka says he doesn't throw the gyroball, but he did say he was working on it.  There is now a video on youtube of that is supposedly it.  I've never seen a pitch move like this.  It sinks and fades away from lefties.  It looks like a change-up on steroids, but the grip is that of a breaking pitch.  I think this may be actually footage of a gyroball.  Anyway, it's a great pitch, whatever it is.
