Pitcher uses Gorilla Arm

[johnnyg08]

Alright guys,

How do you deal with the "gorilla arm" when a pitcher is in the set position and has that dang arm swinging with the ball in his hand. I saw it in two games today using FED rules...what are the official interpretations on this FED and OBR. What are we watching for here? How can we use preventative officiating when dealing with this? I don't see any rules in FED that specifically address the gorilla arm. I guess I'm throwing myself to the wolves here...but I could see situations where a potential illegal feint could take place with a pitcher who uses this stance...help me understand this interpretation fellas...or if there isn't one, clarify that too please. Thank you. I've read FED rule 6 ART 3.
