"Perhaps the "restriction" possibility prevents the player from having to sit out an additional game or games for being "ejected."
This is the case in Illinois - an "unsportsmanlike" ejection results in a "next-game" suspension as well as the game from which the player is ejected. The wording allows the ejection to be deemed not unsportsmanlike, though I'm with you, Carl - how will we know it's just a simple oversight or an intentional (unsportsmanlike) deception?
The turning of the shoulders wording is unclear as well - is it allowed before the pitcher comes set, after the pitcher comes set, or both? Clarifications, clarifications - where is the clarifications department?? Is it anywhere near the clue department?
