Michael Pineda is an Iimbecile

[Phishfan]

As long as you're not physically altering the ball, spitting on the ball, cutting the ball, etc, it's not cheating. 

Absolutely wrong. As long as there is a rule against it, it is cheating. Regardless of if everyone does it. It is just a form of cheating that is overlooked.

Does it help with your grip?  Sure.  Know what else would do that?  Lick your finger tips, which is allowed during cold games.

You sure about this?  From the Official Baseball Rules:

8.02  The pitcher shall not--

(a)

    (1) While in the 18-foot circle surrounding the pitcher’s plate, touch the ball after touching his mouth or lips, or touch his mouth or lips while he is in contact with the pitcher’s plate. The pitcher must clearly wipe the fingers of his pitching hand dry before touching the ball or the pitcher’s plate. EXCEPTION: Provided it is agreed to by both managers, the umpire prior to the start of a game played in cold weather, may permit the pitcher to blow on his hand.

It looks like you can blow on your hands (with explicit prior agreement from both managers), but I don't see anything saying you can lick your fingers.
