That's some crazy stuff. I can't say I'm a big fan of calling it the "gyroball," though. I mean, honestly... it sounds like something out of a cheezy, futuristic baseball movie where there are trampolines in the outfield and pits filled with fire in the basepaths.
Regardless, I hope Matsuzka gets posted. It would be interesting to see if big-leaguers could his that junk.
