If you speak to OPP (you can find him sometimes in the chat room), he will tell you that there is a long road ahead.
However, I saw Zach pitch two innings and he does have the composure of a seasoned pitcher.
If any of you are wondering why he is so special, he is deceptive, great mechanics, polished, releases just about the same spot every time (as pointed out by Big), and has a very effective CHANGE UP. He also gets into a very good rythym, which is most important. In other words, he is in COMMAND. I don't think he has to pitch in the upper 90's to be effective. I also hear is a fine young man.
Zach is the perfect example of why one succeeds as a pitcher, he has all the right "stuff".
So all you dads (and moms) out there, get the little guys off the curve, improve mechanics and teach the fastball and change up!
