My understanding of the rules is that
in FED the pitcher may touch his pitching hand to his mouth while on the mound as long as he wipes off that hand before it touches the ball. In OBR the pitcher may not touch his pitching hand to his mouth anywhere within the dirt portion of the pitching mound[Baseball Rules Differences 17th Edition *336 [pg 62]
My experience doing Connie Mack ball in the summer is that expectations of pitchers and coaches is that this will be called using OBR the same way it is called in High School i.e. the pitcher can do so on the mound [but not the rubber] as long as he wipes it off. This is the way we call it in Nassau County on Long Island. Any comments?
